Replacing an A-Class Server Exchange Base Unit (EBU)

Overview

When troubleshooting a defective A-Class server has determined that the fault lies in a portion of the server that cannot be replaced at the site, field-replaceable components must be removed prior to exchanging the defective server for an operational unit. This "stripped-down" server is the EBU.

The following subsections apply:

Ensure that you obtain required Web Console configuration data (user names and passwords, IP address, etc.) prior to replacing the EBU.

	NOTE: Web Console user login information and passwords are not retained by, and cannot be acquired by, the Web Console. This information is kept by the Web Console Administrator or System Manager.

The following configuration information can be obtained from the Web Console Main Menu:

When the new EBU has been received, place the original system and the new EBU side-by-side on an ESD-protected work area. Now you can remove the FRUs from the original system and install them directly into the new EBU.

	CAUTION: The procedures in this section require opening the system cabinet and exposing the system to electrostatic discharge. Always observe all electrostatic precautions when working with components inside or out of the cabinet. Failure to follow these precautions may result in component damage or loss of system reliability.

Removable Components

The components listed below must be removed from the defective server prior to exchanging it for an operational unit. Click on each name to link to the remove/replace instructions for that item.

	NOTE: As you remove the memory and I/O cards from the original system, note the slots from which they came. They must be installed in the same slots in the EBU to ensure that the system operates properly.

If you don't know the order in which the I/O cards were removed, refer to a recent ioscan (or other mapping utility) output. The information shown below can be used to match a path with an I/O card slot:

Slot 1 is the TOP slot and slot 2 is the BOTTOM slot, when looking at the server from the rear. The "x" is an operator-input variable.

If you don't know the order of memory card removal, refer to the Memory Loading Rules on the label located under the server lid, attached to the top.

Move the Components to the EBU

The following paragraphs discuss how to transfer the components from the server to the EBU.

Unpack the EBU

When the new EBU is received, follow the directions in the A-Class Server Unpacking Instructions section.

	NOTE: The contents in the new EBU carton may vary from those listed in the unpacking instructions section.

Apply New Labels

Each new EBU is shipped with the following labels:

• A5182-84002: Plastic label with A5183A, A1880C, and HP logo markings.

• A5182-84004: Bar coded label with A5183A markings.

• A5182-84005: Three blank stickers.

After you have switched the original system FRUs to the new EBU, locate and apply the labels listed above to the corresponding area on the rear of the new EBU.

Labels Applicable To All Models

First, copy the serial number, located on the server's rear label, from the original system to one of the blank stickers. The serial number is a 10 character number beginning with three alpha characters followed by seven numeric characters. For example:

USJ0009837

Place the new sticker with the original system serial number in the field marked "Serial Number" on the new EBU.

	NOTE: Serial numbers are used to verify Warranty and Hardware Support levels. ALWAYS transfer the serial number of the original system to the new EBU.

Next, copy the LAN station address, located on the server's rear label, from the original system to one of the blank stickers. The LAN station address consists of 12 alphanumeric characters.

	NOTE: DO NOT enter the "Web Console MAC Address" value, located just above the LAN station address. Enter the "LAN Station Address" value ONLY.

Place the new sticker with the original LAN station address in the field marked "LAN Station Address" on the new EBU.

The third blank sticker is an extra.

Labels Applicable to the A5183A (A180C) EBU

Locate the plastic sticker that contains the numbers, A5183A and A180C, and includes the HP logo. Paste it over the original label on the rear of the new EBU. The difference between labels is the modification of the model number from A180 to A180C.

Locate the new bar coded sticker with A5183 markings and place it on the rear label of the new EBU in the field marked, "Product Number" (over the A5182 text).

Reinstall the System

If the replacement A-Class server is used as a single independent unit, refer to the Chapter 2 “A-Class Server Installation” subsection of the Stand-Alone A-Class Server Unpack and Install instructions.

If the replacement server is to be re-installed in an HP-approved cabinet, refer to the Chapter 2 “A-Class Server Installation” subsection of the Cabinet-Mounted A-Class Server System Unpack and Install instructions.

When the basic reinstallation procedures are complete, refer to the Chapter 2 “A-Class Server Installation” instructions to reconnect the replacement server to external devices and power. This information is also found in the Cabinet-Mounted A-Class Server System Unpack and Install instructions.

Restart the System

Refer to the Chapter 2 “A-Class Server Installation” section for applying power to and initiating selftest on both the server and other external devices, and booting the system.

The integrated A-Class Web Console will require reconfiguring. Follow the Chapter 2 “A-Class Server Installation” instructions in the A-Class Server Power Up and Boot Procedures section to complete this task.

When the replacement server is powered up and selftest has successfully completed, you will be prompted to enter the LAN Station Address. This is a one-time prompt that only occurs during the initial system configuration.

The terminal will display: W ARNING: The system LAN Station Address has not been set.

The System LAN Station Address is not set.
WARNING: The LAN Station Address can be set one time only.

Set now [Y/N]?
Type Y and press Enter. The "LAN Station Address" value is located on the rear of the system.
Do not enter the value for the "Web Console MAC Address".

	NOTE: As it appears on the rear label, the LAN Station Address does not include a hyphen (-). However, a hyphen is required (for example: xxxxxx-xxxxxx) when entering the LAN Station Address at this prompt.

This action cannot be undone.
Confirm LAN Station address 0060b0-83c41b [Y/N/Q(uit)]? Type Y and press Enter.

The terminal will display: The system has been initialized with LAN Station Address 0060b0-83c41b.

	NOTE: The system will reset itself, re-run selftest, and perform a normal power-on selftest.

The replacement server is now ready to continue normal boot and power-up procedures.
