IBM 2145UPS-1U User Manual

Note: To make the SAN Volume Controller cluster more resilient to power failure,
the 2145 UPS-1Us can be connected to the redundant ac power switch. If a
redundant ac power switch is not used, connecting the two UPS units that
are powering an I/O group to different, independent electrical power
sources allows the SAN Volume Controller cluster to continue to operate
with reduced capacity if a single power source fails.
Before you begin this task, see the user’s cable connection table, which is provided
at http://www.ibm.com/storage/support/2145. Use this table to identify the 2145
UPS-1U to which this SAN Volume Controller 2145-8G4 is to be connected.
Perform the following steps to connect the SAN Volume Controller 2145-8G4 to the
2145 UPS-1U:
1. At the back of the SAN Volume Controller 2145-8G4, plug the power cable of
the combined power and serial cable into the power connector
