Connect the SAN Volume Controller to
the 2145 UPS-1U to
protect your data in the event of an unexpected loss of external power.
Attention: The SAN
Volume Controller 2145-4F2 node
is supported only in SAN Volume Controller 4.3.1
and earlier releases.
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 2145-4F2 to
the 2145 UPS-1U:
- At the back of the SAN
Volume Controller 2145-4F2,
plug the combined power and serial cable into the power connector (
in Figure 1). Figure 1. Connecting the SAN

- Place the other end of the power cable into the rightmost
load segment 2 receptacle
on the 2145 UPS-1U. DANGER
You
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
that
is located on the SAN
Volume Controller 2145-4F2.
- Place the other end of the signal cable into the communication
port
on the 2145 UPS-1U.
The SAN
Volume Controller 2145-4F2 power
is now connected to the 2145 UPS-1U.
