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 user's cable connection table, which is described in the IBM® System Storage® SAN Volume Controller Planning Guide and was 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 2145-8G4 to the 2145 UPS-1U:
- 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
, as shown in 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 2145-8G4.
- Place the other end of the signal cable into the
communication
port on the 2145 UPS-1U.
The SAN Volume Controller 2145-8G4 power is now connected to the 2145 UPS-1U.
