2145-8F2 power backplane
The SAN Volume Controller 2145-8F4 or SAN Volume Controller 2145-8F2 power backplane might have
to be replaced.
Take precautions to avoid damage from static electricity. Wear an anti-static wrist strap and use a
static-protected mat or surface. For more information, see "Handling static-sensitive devices" on page xix.
Perform the following steps to remove the power backplane:
1. Turn off the node while ensuring that its data is mirrored and synchronized. See MAP 5350 in the
IBM System Storage SAN Volume Controller 2145 Troubleshooting Guide for more information.
2. Remove the SAN Volume Controller 2145-8F4 cable retention bracket.
3. To make sure that you can replace all cables in the same ports from which they were removed, record
the position of all fibre-channel and Ethernet cables; then remove all cables from the back of the node.
4. 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 40.
