IBM SAN Volume Controller 2145-CG8 Hardware Maintenance Manual page 311

Notes:
1. All left or right observations are when you are looking at the front of the unit.
2. You must remove a number of components before you can remove and replace the system board. You
will reuse all the components that are removed with the new system board. Therefore, take care when
you remove and store these components.
Perform the following steps to remove the system board:
1. Ensure that the node is turned off. If the node is an active member of a cluster, you must take care
not to turn off the only node servicing one or more VDisks, because the host applications will lose
access to their data. See MAP 5350 in the IBM System Storage SAN Volume Controller Troubleshooting
Guide for more information.
2. Remove the node from the rack and place it on a flat, static-protective surface. See "Removing the
SAN Volume Controller from a rack" on page 46.
3. Remove the top cover. See "Removing the top cover" on page 77.
4. Remove the Fibre Channel adapter and riser card in slot 1. Set the adapter and riser card aside on
the static-protected surface. See "Removing the Fibre Channel adapter assembly" on page 178.
5. Remove the riser card in slot 2.
6. Disconnect the first set of cables from the system board, which are shown in Figure 281 on page 282.
From the left front side of the system board, remove the following:
a. The right disk signal cable connector
b. The left disk signal cable connector
c. The fan 1 connector
then pull up.
d. The fan 2 connector
