The Netra CP2140 board can be mounted in various enclosures. It can be deployed in various electrical configurations to suit each end-user's requirements. For example, the host board can be used with a transition card and configured to boot from a network as a diskless client. Alternatively, industry-standard PMC and PIM hardware from independent hardware vendors (IHVs) can provide local disk I/O which can optionally be used as a boot path. The basic installation procedure is independent of the type of enclosure used: a floor-mounting rack, a bench-top cabinet, or some other configuration. The memory is user-configurable. See FIGURE 2-1 for Netra CP2140 board hardware configuration examples.
FIGURE 2-1 shows the board hardware configuration options. For more information you see the product website at:
The XCP2040-TRN I/O Transition Card is installed from the rear of the CompactPCI enclosure and interfaces with the host board's I/O connectors J3, J4, and J5 through the backplane. The backplane carries two RJ45 ports, two serial ports, two parallel ports, one floppy port, two SCSI ports, and two USB ports out to its rear panel. FIGURE 2-2 shows the major components and connectors of the Netra CP2140 board. FIGURE 2-8 shows the physical interface between two Netra CP2140 host boards and two transition cards. To see a typical Netra CP2140 board with memory installed see FIGURE 2-5.
FIGURE 2-3 shows the XCP2040-TRN Transition Card and its connectors.
The Netra CP2140 board installs into a customer-supplied 6U chassis. It is important to review the information in the following sections before installing the host board. TABLE 2-2 lists the items to check before installing the board.
The Netra CP2140 board system requires various other hardware and software components which are necessary for proper operation. The OEM customer is responsible for providing the following components as required:
The latest product information along with technical manuals are available on the Web. It is important to read the Netra CP2140 Product Note document (816-4870-xx) that is shipped with the board. For online documents and other information related to the Netra CP2140 board, visit the following Web site:
To determine your power supply requirements see Chapter 3.
The Netra CP2140 board requires the latest OpenBoot PROM compatible with your Solaris operating environment. The board is shipped with the version of OpenBoot PROM available at the time of manufacture (version 4.0.x). The OpenBoot PROM might be out-of-date by the time you get this board.
Ensure that the proper physical, electrical, and environmental preparations have been completed before the installation. For a list of the Netra CP2140 board specifications, see Chapter 2. Make sure that the following conditions are met:
Note - You might need the MAC (Ethernet) addresses of the local hosts to make name server database entries. The MAC address is displayed in the console output while booting to the ok prompt. It can also be derived from the host ID seen on the label of the MAC address (SEEPROM) package (MAC = 8.0.20.hostid). The different network services can be located on a single server to simplify the configuration.
Carefully read the Important Safety Information for Sun Hardware Systems (816-7190-xx) document included in your board kit and the following statements before you install or remove any part of the system.
Caution - Installation of this product requires specific training and technical knowledge. These instructions have been provided for use by Sun Microsystems trained personnel. This equipment uses electrical power internally that is hazardous if the equipment is improperly assembled or disassembled. Although this and some other boards are designed for hot-swap operation, other components must not be subjected to such stresses. Do not disassemble or service the system if the power is connected to the chassis. Follow all safety procedures to avoid injury to personnel and damage to equipment. Before you begin to install or remove a board or any other components, make sure the system power is turned off and the system power cord is removed from the AC source.
Here are the general steps to configure, install, and set up a Netra CP2140 board system. Ensure that the guidelines outlined in Section 2.3, Preinstallation Checklist are met before configuring and installing the board.
2. Install the CP2140 into an enclosure (see Section 2.10, Installing the Netra CP2140 Board).
4. Connect a SCSI interface, if applicable to your system. Connect the SCSI interface with a cable to one of the SCSI connectors on the XCP2040-TRN Transition Card. Also connect any other necessary cables to the XCP2040-TRN Transition Card. For further details, see Section 2.13, Connecting Devices to a XCP2040-TRN I/O Transition Card.
5. Install the Solaris operating environment (see Section 2.15, Software Installation).
6. Connect the CP2140 to the server using existing Ethernet lines or run the CP2140 as a standalone system (see Section 2.17, Standalone Operation).
This section describes how to configure related hardware such as memory modules, PMC modules, and the XCP2040-TRN Transition Card. Most of this hardware must be configured before the CP2140 is installed.
The CP2140 can accommodate both single- and double-wide memory modules. FIGURE 2-4 shows two typical memory modules used on the Netra CP2140 board.
Up to two modules in any supported memory configuration can be installed in any combination (512 Mbyte, 1 Gbyte). However, if two memory modules need to be installed and one of the modules is double-wide, the double-wide module should be installed first (on the bottom). Refer to Section 3.1.2, Main Memory for a list of possible memory module configurations.
FIGURE 2-5 shows a typical SDRAM memory module installed on a CP2140.
The PCI Mezzanine Card (PMC) is installed on J3001, J3002, and J3003 connectors on the motherboard. These connectors interface with the matching connectors on the PMC board: PN1, PN2, and PN4, respectively. The PMC is secured with two mounting posts and screws. Refer to the user documentation from the PMC card manufacturer on how to install the PMC module. FIGURE 2-6 shows how the PCI Mezzanine Card is installed.
This device is installed on the motherboard at the factory. This step is not necessary unless you are installing a replacement board that does not have the host ID. If you must return the CP2140 to the factory, remove this EEPROM from the board before shipping it to the factory. The Serial I2C EEPROM is the MAC address carrier and it stores the backup copy of the board MAC address and host ID information (see Section 126.96.36.199, Serial I2C EEPROM).
To correctly position the EEPROM and to precisely install it on the CP2140, see FIGURE 2-7.
Follow all the safety rules described in Section 2.4, Safety when installing any hardware into the CompactPCI chassis enclosure.
A number of CompactPCI chassis enclosures come with an internal power supply and fan. FIGURE 2-8 shows two Netra CP2140 boards (system host and satellite host) being installed in a CompactPCI chassis.
Smaller CompactPCI enclosures have four board slots. One of these slots is reserved for one 6U form factor board, while the remaining three slots are for either 3U or 6U boards. The larger eight-slot enclosures have two 6U and six 3U slots. In addition, some special CompactPCI enclosures are equipped with a backplane that enables board connection to the front and rear of the chassis.
Install the transition card before installing the Netra CP2140 board. This step is important if the chassis is powered-on during the installation. The transition card is not hot-swappable. Take the step as a safety precaution.
3. Slide the CP2140 into the appropriate slot on the corresponding top and bottom mounting rails and towards the backplane while gently keeping the board handles pushed inward (see FIGURE 2-8 and FIGURE 2-9).
While pushing the board, ensure that the CP2140 extraction levers are aligned perpendicular to the card flange in the unlocked position and that the board connectors are aligned with the transition card connectors.
The transition card can also be fitted with IHV-supplied PCI interface modules (PIMs) which are configured to bring I/O channels to the unit rear panel. A unit of PIM hardware is a kit that includes a card for the PMC slot and a card for the PIM slot on the transition card. A PIM is essentially a rear-panel extension added to a PMC module.
You can order the XCP2040-TRN Transition Card, build a compatible custom card, or buy from an IHV. A minimal set of I/O must provide for a boot path for the host board and a path for console I/O to deliver commands and to read board and system status.
1. Connect the Ethernet (if required) where shown in FIGURE 2-3.
Caution - There are a total of three serial port connections available (one on the CP2140 and two on the XCP2040-TRN I/O Transition Card). At any one time, up to two serial ports can be used. The serial port connector (TTYA) on the XCP2040-TRN I/O Transition Card and the serial interface on the CP2140 cannot be used at the same time.
If you have connected SCSI peripherals that receive power from a source separate than the system's power supply to a system containing a Netra CP2140 board, you must power on the system prior to powering on SCSI peripherals. After powering on the system, you can safely power on the external SCSI peripherals.
A blue LED is lit on a hot-swappable board during extraction process to indicate that it is permissible to extract the board. The blue LED indicates that the system software has been placed in a state for an orderly removal of a board.
During the insertion process, when a board is hot inserted, the blue removal LED is lit again automatically by the system hardware until the hardware connection process is complete. The blue LED is turned off by the software until it indicates once again that the removal of a board is permitted.
Two ejector handles are used for inserting and removing a CompactPCI board. The lower ejector handle is tied to a latch, which when pressed, informs the system that the board is ready for extraction. When the system has unconfigured the board, a blue LED is lit indicating that the board is ready for extraction. You must wait until the blue LED is lit before removing the board.
The cfgadm command provides configuration administration operations on dynamically reconfigurable hardware resources. Configuration administration is performed at attachment points, places where system software supports dynamic reconfiguration of hardware resources during continued operation of the Solaris operating environment.
Configuration administration distinguishes between hardware resources that are physically present in the server and hardware resources that are configured and visible to the Solaris software. The nature of configuration administration functions are hardware-specific and are performed by calling hardware-specific libraries. Refer to the man pages (by typing man cfgadm) for additional information on the options associated with this command.
3. Slide the new I/O board into the top and bottom mounting rails in the same slot into the backplane while gently keeping the board handles in the open position. Once the board is all the way in, lock the ejector handles (see FIGURE 2-10).
The blue LED is lit once the board makes complete contact with the backplane. The LED goes off shortly after the ejector handles are closed, if the hardware initialization of the board is successful. Otherwise, it remains lit, indicating that the board must be replaced.
Hot-swapping a line card does not require the system power to be turned off. Refer to the chassis manufacturer's documentation for slot assignments and additional information. In addition, a full hot-swap board does not require running the cfgadm administrative command. The system automatically configures the card for using the system resources. The board-specific configuration steps are still necessary after the completion of host-specific configuration.
4. Slide the new I/O board into the top and bottom mounting rails in the same slot into the backplane while gently keeping the board handles in the open position. Once the board is all the way in, lock the ejector handles (see FIGURE 2-10).
FIGURE 2-10 shows how to release and to lock the CP2140 injector/ejector handles.
The blue LED is lit once the board makes a complete contact with the backplane. The LED goes off shortly after the ejector handles are closed, if the hardware initialization of the board is successful. Otherwise, it remains lit, indicating that the board must be replaced.
Note - To comply with NEBS Level 3 Intrabuilding Lightning Surge Tests (Telecommunications Port), the intrabuilding cabling must be shielded and the shield must be grounded at both ends. Refer to GR-1089-CORE, Section 4.5.9.
Caution - For SCSI A, both internal and external SCSI connectors are on the same SCSI A bus. Use only one connector at a time to avoid signal problems on the SCSI chain. Also, the SCSI cable cannot exceed more than 9 feet (3 meters) in length to avoid possible data errors.
The CP2140 configuration supports IHV CompactPCI cards. To add CompactPCI cards and drivers, refer to the documentation provided with the CompactPCI card. Usually software drivers and related documentation are provided on the CD or floppy diskettes. Read all documentation furnished with the package. The manufacturer's Web site might also have the latest product and driver information.
It should show the PCI bus instances #0 and #1 for the two PCI buses on the CP2140. There are instances of various PCI cards connected to each one. A PCI card might show up as pciVVVV,DDDD, where VVVV is the vendor ID, for example, 1011 and DDDD is the device ID, for example 008e. If the driver for the card is already loaded, then you might see the device name supplied by the driver in the device tree.
For details on output information, see Section 6.6, Determining Firmware Version.
The CP2140 requires the Solaris 8 2/02 operating environment software. CP2000 Supplemental CD 4.0 for Solaris 8 is available that offers additional features for the CP2140 such as CompactPCI net driver support and satellite hot-swap support. CP2000 Supplemental CD 3.1 for Solaris 8 can also be used with the Netra CP2140 board, but does not contain all of the features available on CD 4.0.
b. Type the Ethernet address obtained in Step a into the install server as a boot client.
The minimal necessary infrastructure to enable network computing involves a boot server with networking software and the CP2140. The boot server senses the CP2140 booting up on the network and supplies the client with its boot image: Solaris software.
An administrator can also choose a separate Internet Message Access Protocol version 4 (IMAP4) server and a home directory server. These software services can be installed on a single server or spread out over several servers.
The CP2140 provides a complete I/O subsystem and can operate as a standalone computer for development purposes or other special applications. The CP2140 provides two UltraWide single-ended SCSI connections that are accessible through the rear of a special CompactPCI chassis that contains a backplane. This enables connection to a hard drive, tape, or a number of other SCSI devices. Software can be downloaded through the internet or from a CD into a hard drive connected to the XCP2040-TRN I/O Transition Card.
