Connect the SAN Volume Controller to the 2145 UPS-1U to protect your data in the event of an unexpected loss of external power.
Note: To make the SAN Volume Controller cluster
more resilient to power failure, the 2145 UPS-1U units
can be connected to the redundant ac-power switch.
If a redundant ac-power switch is
not used, you can connect the two uninterruptible
power supply units
that are powering an I/O group to different, independent electrical
power sources. If a single power source fails, the SAN Volume Controller cluster
can then continue to operate with reduced performance.
Before you begin this task, see the completed customer's cable-connection table, which is described in the IBM® System Storage® SAN Volume Controller Planning Guide and can be downloaded from www.ibm.com/storage/support/2145.
Use the information in this table to identify the 2145 UPS-1U unit to which this node is to be connected.
Perform the following steps to connect the SAN Volume Controller to the 2145 UPS-1U:
- At the back of the SAN Volume Controller 2145-8F2 or
the SAN Volume Controller 2145-8F4,
plug the combined power and serial cable
into the power connector
. See Figure 1.

- Place the other end of the power cable into the
rightmost
load segment 2 receptacle on the 2145 UPS-1U. DANGERYou have already switched on the 2145 UPS-1U. The output sockets of the 2145 UPS-1U are live.
- Plug the signal cable into the serial connector located
on the SAN Volume Controller 2145-8F4 or
the SAN Volume Controller 2145-8F2.
- Place the other end of the signal cable into the
communication
port on the 2145 UPS-1U.
The SAN Volume Controller power is now connected to the 2145 UPS-1U.
