Removing The System Backplane From An Air-Cooled 8335-Gtb - IBM Power System S822LC Manual

Before you begin
Before you begin replacing the system backplane, record the system serial number and machine model
type. After you replace the system backplane, you must set the system serial number and machine model
type into the replacement system backplane.
After you replace the system backplane, you must set the system serial number in the system backplane
by using the vital product data (VPD) update tool. To download the tool, complete the following steps:
1. Go to the IBM Support Portal website(www.ibm.com/support/entry/portal/product/power/scale-
out_lc).
2. In the search field, enter your machine type and model. Then, click the correct product support entry
for your system.
3. From the Downloads list, click Scale-out LC system VPD update tool.
4. Follow the directions that are provided with the tool to update the VPD.
As part of the system processor module replacement, the heat sink is removed. The system can use two
types of thermal interface materials (TIMs); silver with trimmed corners, or gray with square corners.
v When the heat sink is removed from the system processor module, the silver-colored thermal interface
material (TIM) is typically adhered to the heat sink. Unless damaged, the TIM that is adhered to the
heat sink can be reused. If the silver-colored TIM is damaged, do not reuse the removed heat sink.
Before you begin the removal and replacement procedure, ensure that you have a spare TIM and heat
sink, part number 01AF286, on hand.
v If a gray-colored TIM is used and needs replacing, ensure that you have a spare TIM, part number
01AF742, on hand. Alternatively, have a spare TIM and heat sink, part number 01AF286, on hand.
Procedure
1. Create a backup of the BMC by completing the following steps:
a. Access the BMC GUI from a browser. The user needs Administrator privilege. You can use either
Google Chrome or Mozilla Firefox browsers.
b. Navigate to Maintenance > IPMI Configuration
c. Press the Save button to create the backup. The file is named save_config.bin
2. Save the BMC network settings by completing the following steps:
a. Navigate to HMC Management > Console Settings > Change BMC/IPMI Network Settings
b. Record the following values:
IP address
Subnet mask
Gateway
3. Power off the system and place it in the service position. For instructions, see "Preparing the
8335-GTB system to remove and replace internal parts" on page 195.
