2. Reconnect to the system board the cables that you disconnected in step 10 on
page 178 of "Removing the system board" on page 177.
3. Rotate the system-board thumbscrews toward the rear of the file module until
the latch clicks into place.
4. Install the fans.
5. Install each microprocessor with its matching heat sink (see "Installing a
microprocessor and heat sink" on page 170).
6. Install the DIMMs (see "Installing a memory module" on page 153).
7. Install the air baffle (see "Installing the air baffle" on page 138), making sure
that all cables are out of the way.
8. Install the 10 Gbps Ethernet adapter (see "Installing a 10-Gbps Ethernet
adapter" on page 147).
9. Install the PCI riser-card assemblies and all adapters (see "Installing a PCI
riser-card assembly" on page 142).
10. Install the cover (see "Installing the cover" on page 124).
11. Push the power supplies back into the file module.
12. Slide the file module into the rack.
13. Follow the steps at the end of the procedure "Removing a file module and
disconnecting power" on page 92 to reconnect the file module and resume its
use in the cluster.
Note: After you replace the system board, the file module might reboot several
times and it might take up to an hour for the firmware on the new system board
to be updated. Do not use the file module until the firmware update is completed.
Setting the machine serial number
This procedure is for IBM authorized service providers who, after replacing a
system board in one of the file modules, must set the machine serial number vital
product data stored on the system board using the Advanced Settings Utility
(ASU). The following procedure is for a field replaceable unit (FRU). FRUs must be
installed only by trained service technicians. The serial number must be set to the
value that is visible on the MT-M SN label on the front of the file module.
About this task
The ASU package is part of the Storwize V7000 Unified code. ASU is available to
authorized service personnel from the command-line interface (CLI) on the file
module. Use ASU to modify selected settings in the integrated-management-
module (IMM)-based Storwize V7000 Unified file modules.
Procedure
1. Access and log in to the file module with the new system board as root.
ssh -p 1602 root@<file module IP>
You are prompted for the file module root password.
2. If the MT-M SN label on the front of the file module has 2073-720, issue the
following command to set the SysInfoProdName:
asu set SYSTEM_PROD_DATA.SysInfoProdName 7915PJQ
3. Issue the following command to view the current setting of the serial number:
asu show SYSTEM_PROD_DATA.SysInfoSerialNum
4. Issue the following ASU command on the Storwize V7000 Unified file module
to set the serial number:
181
