Netra CT Server Product Overview

Components within the Netra CT servers can be broken down into three categories:

• Components available for both front and rear-access model servers
• Components available only for the front-access model servers
• Components available only for the rear-access model servers

In addition, some components are available only for the Netra CT 810 server, some are available only for the Netra CT 410 server, and some are available for both types of servers.

Finally, components can be further broken down into either hot-swappable or cold-swappable components:

• A hot-swappable component is a component that you can install or remove and replace while the server is running, without interrupting the operation of the server. You may have to enter software commands before and after an installation or a removal/replacement of a hot-swappable component to incorporate the new component in the system correctly.
• A non-hot swappable or cold-swappable component is a component that requires that you halt (and, in some cases, also power down) the server before installing or removing and replacing the component.

Refer to TABLE 4-1 for a list of components available for the different models of the Netra CT server. All information applies to both the Netra CT 810 server and the Netra CT 410 server unless otherwise noted.

Components Available for Both the Front-Access and Rear-Access Models

Following are components that are available for both front and rear-access model servers:

• Host CPU Card
• Power Supply Units
• System Status Panel
• System Controller Board
• Air Filters
• Fan Tray and Fans
• Hard Disk Drive
• Removeable Media Module
• Alarm Card

Host CPU Card

Every Netra CT server contains one host CPU card. The Netra CT 810 servers and the Netra CT 410 servers use the same host CPU card. A specific slot is reserved for the host CPU card in both the Netra CT 810 server (slot 1) and the Netra CT 410 server (slot 3), indicated by a red card cage guide. FIGURE 4-1 shows where the host CPU card must be installed in both types of servers.

 FIGURE 4-1 Host CPU Card Locations

On-Board Components

FIGURE 4-2 shows the ports on a host CPU card. The TTY A port is available on the host CPU card for the front-access model of the Netra CT 410 server because the CPU front transition card for the Netra CT 410 server does not have a TTY A port (see Host CPU Front Transition Card for more information on the CPU front transition card for the Netra CT 410 server). Do not use the TTY A port on the host CPU card for the rear-access models of the Netra CT 810 server or Netra CT 410 server because the CPU transition cards for those models all have a TTY A port.

 FIGURE 4-2 Host CPU Card

Restrictions for the Netra CT Server

The documentation that comes with the Netra CP2140 host CPU card explains how to set the SMC module settings on the SW0501 switches when installing a Netra CP2140 host CPU card into high availability chassis or a non-high availability chassis. The Netra CT server supports high availability hot swap; however, because the alarm card controls the high availability on the Netra CT server, the settings on the SW0501 switches should actually be set in the default, non-high availability settings.

Following are the correct (default) settings for the SMC module switch SW0501 for the Netra CT server (see FIGURE 4-3 and FIGURE 4-4):

• Switch 1--Closed (switch is set in direction of arrow)
• Switch 2--Closed (switch is set in direction of arrow)

 FIGURE 4-3 Location of SW0501 on SMC Module

 FIGURE 4-4 Switch SW0501 in Closed Position (Default) for the Netra CT Server

Power Supply Units

Every Netra CT 810 server contains two power supply units, and every Netra CT 410 server contains one power supply unit. The Netra CT 810 servers and Netra CT 410 servers use the same power supply units.

For the Netra CT 810 server, one power supply unit is redundant of the other. Feeds are supplied to each of the power supply units through the DC power distribution units or AC power entry unit (see Chapter 2 for more information). Because each Netra CT 810 server has two power supply units, the server receives power from two power sources. If one power source or one power supply unit fails, the server will continue normal operation using the remaining power supply. Note that this is not the case for the Netra CT 410 server because it has only one power supply unit.

The locations of the power supply units in the Netra CT 810 server are illustrated in FIGURE 4-5 and the location of the power supply unit in the Netra CT 410 server is illustrated in FIGURE 4-6.

 FIGURE 4-5 Power Supply Unit Locations (Netra CT 810 Server)

 FIGURE 4-6 Power Supply Unit Location (Netra CT 410 Server)

System Status Panel

The system status panel is a module designed to give feedback on the status of the key components within the Netra CT servers. The location of the system status panel in the Netra CT 810 servers and Netra CT 410 servers is illustrated in FIGURE 4-7.

 FIGURE 4-7 System Status Panel Locations

The system status panel has one set of LEDs for each component within that particular server. FIGURE 4-8 shows the LEDs on the system status panel for the Netra CT 810 server, and FIGURE 4-9 shows the LEDs on the system status panel for the Netra CT 410 server.

 FIGURE 4-8 System Status Panel (Netra CT 810 Server)

 FIGURE 4-9 System Status Panel (Netra CT 410 Server)

Each major component in the Netra CT 810 server or Netra CT 410 server has a set of LEDs on the system status panel that gives the status on that particular component. Each component will have either the green Power and the amber Okay to Remove LEDs (FIGURE 4-10) or the green Power and amber Fault LEDs (FIGURE 4-11). Note that the components in the Netra CT servers all have the green Power LED, and they will have either the amber Okay to Remove LED or the amber Fault LED, but not both.

 FIGURE 4-10 Power and Okay to Remove LEDs

 FIGURE 4-11 Power and Fault LEDs

• TABLE 4-4 gives the LED states and meanings for any CompactPCI boards installed in a slot in the Netra CT 810 server or Netra CT 410 server.
• TABLE 4-5 gives the LED states and meanings for any component other than a CompactPCI board that has the green Power and amber Okay to Remove LEDs.
• TABLE 4-6 gives the LED states and meanings for any component other than a CompactPCI board that has the green Power and amber Fault LEDs.

There is also a green system power LED and power on/off button located on the system status panel. When the system is off, the system power LED will be unlit. Pressing the system power button when the system is off will start the power-up sequence. Once the system is completely powered up, the system power LED remains on.

When the system is powered on, pressing the system power button for less than 4 seconds will start the orderly power-down sequence--in a manner that no persistent operating system data structures are corrupted--indicated by a blinking LED. In the orderly power-down, applications in service may be abnormally terminated and no further services will be invoked by the CPU. Once the CPU has reached a quiescent state (run level-0, as if init 0 had been invoked), then the power suppl(ies) will turn off, indicated by the LED changing from a blinking state to the off state.

If the button is held down for 4 seconds or longer, the power suppl(ies) are turned off without any intervention of the CPU; that is, the "emergency" power-down sequence occurs.

System Controller Board

The system controller board is a hot-swappable component located behind the system status panel; you must remove the system status panel to access the system controller board. The system controller board feeds system status information to the system status panel, where LEDs give feedback on the status of the key components within the Netra CT servers.

The location of the system controller board in the Netra CT 810 server is illustrated in FIGURE 4-12 and the location of the system controller board in the Netra CT 410 server is illustrated in FIGURE 4-13.

 FIGURE 4-12 System Controller Board Location (Netra CT 810 Server)

 FIGURE 4-13 System Controller Board Location (Netra CT 410 Server)

Air Filters

Both the Netra CT 810 servers and the Netra CT 410 servers have two types of air filters: a power supply unit air filter, which filters the air going into the power supply, and a main air filter, which filters the air going into the server. Both air filters are located in the power supply unit. The power supply unit air filter is located at the front of the power supply unit and the main air filter is located in a tray at the top of the power supply unit. Both sets of air filters should be replaced every three to six months. If your server environment is especially dirty, you may have to replace them more frequently. The power supply unit air filter must be in place for safe operation. FIGURE 4-14 shows the locations of the air filters in a Netra CT 810 server power supply unit, and FIGURE 4-15 shows the locations of the air filters in a Netra CT 410 server power supply unit.

Caution - There is an energy hazard present if the power supply unit air filter is not installed. If you remove the power supply unit air filter, you must replace the filter immediately and replace the outer cover for the safe operation of your system. Refer to the instructions in the Netra CT Server Service Manual for more information.

 FIGURE 4-14 Power Supply Unit Air Filter and Main Air Filter (Netra CT 810 Server)

 FIGURE 4-15 Power Supply Unit Air Filter and Main Air Filter (Netra CT 410 Server)

Fan Tray and Fans

Both the Netra CT 810 servers and the Netra CT 410 servers have two fan trays. The fan tray for the Netra CT 810 server has a single large fan in each tray, while the fan tray for the Netra CT 410 server has two smaller fans in each tray. The fan tray is designed to be hot-swappable.

If the temperature rises above 158°F (70°C), the CPU card sends out a warning that the system is overheating. If the temperature rises above 167°F (75°C), then the system shuts down automatically. Note that the temperatures above are not ambient air temperatures, but rather the CPU temperatures that are monitored by a thermistor located under the heatsink on the host CPU card.

If one fan tray fails, you must replace the failed fan tray as soon as possible. Even though the system can run on one fan tray, if the temperature rises, a single fan tray may not be able to cool the system properly.

The fans are located underneath the card cage behind the system status panel (see System Status Panel for the location of the system status panel). They are recessed into the operations card cage to maximize the air flow across the CompactPCI cards. FIGURE 4-16 shows the locations of the fan trays in a Netra CT 810 server and FIGURE 4-17 shows the locations of the fan trays in a Netra CT 410 server. Note that the system status panel has been removed in both figures.

 FIGURE 4-16 Fan Trays (Netra CT 810 Server)

 FIGURE 4-17 Fan Trays (Netra CT 410 Server)

Hard Disk Drive

Hard disk drives are fully hot-swappable. Each hard disk drive has its own latching mechanism to ensure a positive lock with the chassis. You can have a maximum of two hard disk drives in the Netra CT 810 server and one hard disk drive in the Netra CT 410 server. The Netra CT 810 servers and the Netra CT 410 servers both use the same hard disk drives.

A specific slot is reserved for the hard disk drives in both the Netra CT 810 servers and the Netra CT 410 servers. The hard disk drives will be behind the drive bay cover on your system. There would be a maximum of two hard disk drives behind the drive bay cover in a Netra CT 810 server and one behind the drive bay cover in a Netra CT 410 server.

Following are the SCSI IDs for the hard disk drives:

• Netra CT 810 server
• Upper hard disk drive (HDD 0)--SCSI ID 0 on first SCSI chain (c0t0d0)
• Lower hard disk drive (HDD 1)--SCSI ID 1 on second SCSI chain (c1t1d0)

• Netra CT 410 server
• Hard disk drive (HDD 0)--SCSI ID 0 on only SCSI chain (c0t0d0)

In addition, there are two separate SCSI chains in the Netra CT 810 server for the SCSI devices:

• The upper hard disk drive (HDD 0) and the removeable media device are both on the first SCSI chain. Any external SCSI devices attached to the SCSI port on the CPU front or rear transition card would also be on the first SCSI chain.
• The lower hard disk drive (HDD 1) is the only SCSI device on the second SCSI chain, and should be used as the boot drive.

 FIGURE 4-18 Drive Bay Cover Locations

Removeable Media Module

The removeable media module consists of either a DVD or a 4-mm digital audio tape (DAT) drive, either of which is placed into the system from the front. The removeable media module is available only for the Netra CT 810 server.

Following are the SCSI IDs for the devices used in the removeable media module:

• DVD--SCSI ID 6
• DAT--SCSI ID 5

In addition, there are two separate SCSI chains in the Netra CT 810 server for the SCSI devices. The removeable media device and the upper hard disk drive (HDD 0) are both on the first SCSI chain; the lower hard disk drive (HDD 1) is alone on the second SCSI chain.

 FIGURE 4-19 Removeable Media Module Location

Alarm Card

The alarm card is a standard component for both the Netra CT 410 servers and Netra CT 810 servers. There are two different types of alarm cards used in the two servers:

• The single-wide 6U alarm card (a U is a unit of measure equal to 1.75 inches or 44.45 mm). This alarm card is used in the Netra CT 810 server, and in the diskless version of the Netra CT 410 server.
• The double-wide 3U alarm card. This alarm card is used only in the diskfull version of the Netra CT 410 server.

Significant Reliability, Availability, Serviceability (RAS) functions are provided by the alarm card. The alarm card has its own CPU, a Motorola MPC850 processor, plus its own real-time operating system and application software.

The alarm card and its accompanying software perform the following functions on the Netra CT server:

• Enables you to power on and off the Netra CT server from a remote console
• Notifies an administrator in the event of a component failure
• Gives a hard or soft reset of the CPU board
• Interacts with the network management software on the server to indicate changes in system state

The alarm card has the following remote interfaces:

• Two RJ-45 connectors--one 10 Mbps (Ethernet port 1) and one 10/100 Mbps (Ethernet port 2)
• Two RS-232 serial ports
• One DB-15 alarm port

A specific slot is reserved for the alarm card in both the Netra CT 810 server and the Netra CT 410 server. FIGURE 4-20 shows the single-wide 6U alarm card used in the Netra CT 810 server and the diskless Netra CT 410 server. FIGURE 4-21 shows the double-wide 3U alarm card used in the diskfull Netra CT 410 server.

 FIGURE 4-20 Single-Wide 6U Alarm Card

 FIGURE 4-21 Double-Wide 3U Alarm Card

There is also an alarm rear transition card available for the rear-access models of the Netra CT 810 server and Netra CT 410 server. Either the single-wide 6U alarm card or the double-wide 3U alarm card can be used in conjunction with the alarm rear transition card. The alarm rear transition card must be installed in the same slot, at the rear of the server, as the alarm card. Refer to Alarm Rear Transition Card for more information.

Components Available Only for the Front-Access Models

Following are components that are available only for front-access model servers:

• Host CPU Front Transition Card
• Front-Access Model Satellite CPU or I/O Cards

Host CPU Front Transition Card

The host CPU front transition card is required to provide connections from the host CPU card to standard I/O connectors on the front. The host CPU front transition card for the Netra CT 410 server is 3U and is installed in the slot next to the power supply.

FIGURE 4-22 shows the location of the host CPU front transition card in a Netra CT 410 server. Note that the host CPU front transition card for the Netra CT 410 server does not have a TTY A port, so you must use the COM port on the host CPU card as the TTY A port for the front-access model of the Netra CT 410 server (see Host CPU Card for more information on the COM port on the host CPU card).

 FIGURE 4-22 Host CPU Front Transition Card Location in a Netra CT 410 Server

Front-Access Model Satellite CPU or I/O Cards

Visit the www.sun.com site for more information on satellite CPU and I/O cards that are supported on the Netra CT server.

Card slots designated for satellite CPU, I/O cards and alarm cards have black rails; card slots with red rails are reserved for the host CPU card. There are also labels at the front of the servers and the rear of the chassis that show the I/O slot numbers for front-access and rear-access models, as well as the cards that are supported in each slot. For front-access models, you can also determine the I/O slot numbers for your servers by using the I/O slot numbers shown on the system status panels. A satellite CPU or I/O card cannot be installed in the slots meant for the host CPU card or alarm card. All the slots for satellite CPU or I/O cards in the Netra CT server support hot swap.

The following figures show the slots available for satellite CPU or I/O cards in the Netra CT servers:

• Netra CT 810 server--FIGURE 4-23
• Netra CT 410 server--FIGURE 4-24

 FIGURE 4-23 Supported Locations for Satellite CPU or I/O Cards in a Front-Access Netra CT 810 Server

 FIGURE 4-24 Supported Locations for Satellite CPU or I/O Cards in a Front-Access Netra CT 410 Server

Components Available Only for the Rear-Access Models

Following are components that are available only for rear-access model servers:

• Host CPU Rear Transition Card
• Host CPU Front Termination Board (Netra CT 410 Server Only)
• Alarm Rear Transition Card
• Rear-Access Model Satellite CPU or I/O Cards

Host CPU Rear Transition Card

The host CPU rear transition card is required to provide connections from the host CPU card to standard I/O connectors on the rear. In addition, the host CPU rear transition card provides two MIIs to two 10/100 twisted-pair Ethernet connections. The host CPU card must be installed in the front of the server in order for the host CPU rear transition card to work (refer to Rear-Access Models for more information). The same host CPU rear transition card is used by both the Netra CT 810 server and the Netra CT 410 server.

Use only the Netra CT-supported host CPU rear transition card in the Netra CT server; do not use the XCP2040-TRN I/O transition card that is available with the Netra CP2140 board. Refer to FIGURE 4-25 to determine if the host CPU rear transition card you have is supported or unsupported on a Netra CT server.

 FIGURE 4-25 Supported and Unsupported Host CPU Rear Transition Card for a Netra CT Server

FIGURE 4-26 shows the location of the host CPU rear transition card on the Netra CT 810 server, and FIGURE 4-27 shows the location of the host CPU rear transition card on the Netra CT 410 server.

 FIGURE 4-26 Locating the CPU Rear Transition Card in a Netra CT 810 Server (Top View)

 FIGURE 4-27 Locating the CPU Rear Transition Card in a Netra CT 410 Server (Top View)

Host CPU Front Termination Board (Netra CT 410 Server Only)

The host CPU front termination board is installed in the slot that would normally be occupied by the host CPU front transition card in a front-access model of the Netra CT 410 server. The host CPU front termination board terminates the SCSI chain for the rear-access Netra CT 410 server.

Alarm Rear Transition Card

The alarm rear transition card extends the ports on the alarm card installed at the front of the server to the alarm rear transition card installed at the rear of the server. The same alarm rear transition card is used by both the Netra CT 810 server or the Netra CT 410 server. The alarm card must be installed in the front of the server in order for the alarm rear transition card to work (refer to Rear-Access Models for more information). Ethernet port 1 is a 10Mbps Ethernet port, and Ethernet port 2 is a 10/100 Mbps Ethernet port. FIGURE 4-28 shows the ports for the alarm rear transition card. FIGURE 4-29 shows the location of the alarm rear transition card in a Netra CT 810 server, and FIGURE 4-30 shows the location of the alarm rear transition card in a Netra CT 410 server.

 FIGURE 4-28 Alarm Rear Transition Card

 FIGURE 4-29 Supported Location for the Alarm Rear Transition Card in a Netra CT 810 Server (Top View)

 FIGURE 4-30 Supported Location for the Alarm Rear Transition Card in a Netra CT 410 Server (Top View)

Rear-Access Model Satellite CPU or I/O Cards

Satellite CPU Rear Transition Card Set

The satellite CPU rear transition card set consists of two separate cards:

• The satellite CPU card (front)
• The satellite CPU rear transition card (rear)

The satellite CPU card is installed from the front of the Netra CT server; however, no cables are connected to the satellite CPU card. It is the same satellite CPU card that is used in the front-access model of the Netra CT server.

The rear transition card extends the ports from the PMCs installed in the satellite CPU card to the PIMs installed in the satellite CPU rear transition card. The satellite CPU card must be installed in the same slot at the front of the server in order for the satellite CPU rear transition card to work. For example, if you install a satellite CPU rear transition card in I/O slot 3 at the rear of a Netra CT 810 server, you must also install the accompanying satellite CPU card in I/O slot 3 at the front of the server.

FIGURE 4-31 and FIGURE 4-32 give graphical representations of how the satellite CPU cards should align with the satellite CPU rear transition cards (RTCs). Note that, if you are facing the front of the server, the I/O slots read from left to right, whereas they read from right to left if you are facing the rear of the server.

 FIGURE 4-31 Supported Locations for Satellite CPU or I/O Rear Transition Card Sets in a Netra CT 810 Server (Top View)

 FIGURE 4-32 Supported Locations for Satellite CPU or I/O Rear Transition Card Sets in a Netra CT 410 Server (Top View)

I/O Rear Transition Card Set

The I/O rear transition card set consists of two separate cards:

• The front I/O card (front)
• The I/O rear transition card (rear)

The front I/O card contains the ASICs for the associated I/O card and is installed from the front of the server; however, no cables are connected to the front I/O card.

The I/O rear transition card extends the ports for a particular I/O card to the rear of the server. The I/O rear transition card and the front I/O card must be installed in the same slot at the front of the server in order for the I/O rear transition card to work. For example, if you install an I/O rear transition card in I/O slot 3 at the rear of a Netra CT 810 server, you must also install the accompanying front I/O card in I/O slot 3 at the front of the server.

When one of the two cards fails, you should replace both the front I/O card and the I/O rear transition card. FIGURE 4-31 and FIGURE 4-32 give graphical representations of how the front I/O cards should align with the I/O rear transition cards (RTCs). Note that, if you are facing the front of the server, the I/O slots read from left to right, whereas they read from right to left if you are facing the rear of the server.

^{1 (TableFootnote) The host CPU card and the host CPU front and rear transition cards are hot-swappable only if the alarm card is also installed in the Netra CT server.}
