Power Redundancy and Requirements

The Sun Netra T5440 server provides four hot-swappable power supplies in a 2+2 redundant configuration. The system will continue operating under the following fault conditions:

A power source failure which removes input power from one or two power supplies.
Failure of one or two power supplies.
Service actions which require removal of one or two power supplies.

The Sun Netra T5440 server may be operated on two, three, or four power supplies depending on the ambient temperature conditions.

Failure to adhere to the following guidelines could result in a temporary system shut down due to activation of over temperature protection in the power supplies.

At room ambient temperatures of 30° C or less, the system may be operated continuously with two or more power supplies functioning.
At room ambient temperatures between 30° C and 45° C, the system may be operated continuously with three or four power supplies functioning.
At room ambient temperatures between 30° C and 45° C, the system may be operated for up to five minutes with two power supplies functioning.
At room ambient temperatures above 45° C, all four power supplies must be functioning.

Changing Sun Netra Rack Servers from AC to DC Input or From DC to AC Input

Safety agency requirements prohibit Sun Microsystems from changing a product from AC input to DC input or from DC input to AC input after the product has been removed from the agency approved manufacturing site.

Additional Power System Information

The total input power for the system is divided equally among the power supplies in operation.
Reversing the positive and negative inputs to the power supplies of a DC input system will not cause damage. However, the power supplies with reversed input will not operate.
The inputs to a power supply are isolated from the system chassis and the other power supply inputs.
The AC or DC power inputs may be at different voltages within the acceptable range and may have different offset voltages relative to the system chassis.

Tools and Equipment Needed

To install the system, you must have the following tools:

No. 2 Phillips screwdriver
ESD mat and grounding strap

In addition, you must provide a system console device, such as one of the following:

ASCII terminal
Workstation
Terminal server
Patch panel connected to a terminal server

Shipping Kit Inventory List

Standard components of the server are installed at the factory. However, if you ordered options such as a PCI card and monitor, these are shipped to you separately.

Note - Inspect the shipping cartons for evidence of physical damage. If a shipping carton appears damaged, request that the carrier’s agent be present when the carton is opened. Keep all contents and packing material for the agent’s inspection.

Verify that you have received all the parts of your server.

Server chassis
19-inch, 4-post hardmount rack kit
Package of mounting screws and nuts in assorted sizes to fit various types of racks and cabinets
Wago Type 831-3203 connectors kit for use with DC PSUs
M5 nuts for use with chassis grounding studs
Any optional components that were ordered with the server

Optional Component Installation

The standard components of the server are installed at the factory. However, if you ordered options such as additional memory or PCI cards, these will be shipped separately. If possible, install these components prior to installing the server in a rack.

Note - There is a 25 Watt maximum load for PCI Slots 0-3, and a 15 Watt maximum load for PCI (or XAUI) Slots 4-9.

If you ordered any options that are not factory-installed, see the Sun Netra T5440 Server Service Manual for installation instructions.

Note - The list of optional components can be updated without notice. See the product web pages for the most current list of components supported in the server. http://www.sun.com/products-n-solutions/hw/networking/

ESD Precautions

Electronic equipment is susceptible to damage by static electricity. Use a grounded antistatic wriststrap, footstrap, or equivalent safety equipment to prevent electrostatic damage (ESD) when you install or service the servers.

Caution - To protect electronic components from electrostatic damage, which can permanently disable the system or require repair by service technicians, place components on an antistatic surface, such as an antistatic discharge mat, an antistatic bag, or a disposable antistatic mat. Wear an antistatic grounding strap connected to a metal surface on the chassis when you work on system components.

Installation Overview

This installation guide provides procedures that are to be performed in the following order.

Verify that you have received all of the components that ship with your server. See Shipping Kit Inventory List.
Gather configuration information for your system. See your system administrator for specific details, including these parameters:
- Netmask
- IP address for the service processor
- Gateway IP address
Install any optional components shipped with your system. If you have purchased other optional components such as additional memory, install them prior to mounting the server in a rack. See Optional Component Installation.
Mount the server into a rack or cabinet. See Chapter 3 for 4-post and 2-post racks.

Note - In the rest of this guide, the term rack means either an open rack or a closed cabinet.

Connect the server to a serial terminal or a terminal emulator (PC or workstation) to display system messages. See Powering On the System for the First Time.

Caution - The serial terminal or a terminal emulator should be connected before you connect the power cables. As soon as power is connected to the system, the service processor immediately powers on and runs diagnostics. Diagnostic test failures will be printed on the serial terminal. For more information, refer to the Integrated Lights Out Manager 2.0 (ILOM 2.0) Supplement for the Sun Netra T5440 Server.

Connect the data cables to the server, but do not connect the power cable yet. See Connecting the Server Cables.

Connect the power cable to the server and examine the display for any error messages. See Powering On the System for the First Time.

Caution - There is a potential for electric shock if the server and related equipment are not properly grounded.

Note - The service processor runs on the 3.3V standby voltage. As soon as AC/DC power is connected to the system, the service processor immediately powers on, runs diagnostics, and initializes the ILOM firmware.

After the service processor boots, access the ILOM command-line interface (CLI) through the serial management port. See Logging In To the Service Processor.
Configure the service processor network addresses. See Configuring the Service Processor Network Management Port.

Note - The service processor network management port is not operational until you configure network settings for the service processor (through the service processor serial management port).
Commit the changes to the service processor network parameters. See Step 14 in Powering On the System for the First Time.
Power on the server from a keyboard using the ILOM software. See Powering On the System for the First Time.
Configure the Solaris OS. See Booting the Solaris Operating System.

The Solaris OS is preinstalled on the servers. When you power on, you are automatically guided through the Solaris OS configuration procedure.
Install any required patches to the server.

Refer to the Sun Netra T5440 Server Product Notes for a list of required patches.
Load additional software from the Solaris media kit (optional).

The Solaris media kit (sold separately) includes several CDs containing software to help you operate, configure, and administer your server. Refer to the documentation provided with the media kit for a complete listing of included software and detailed installation instructions.
