Perform the following steps to install the SAN Volume Controller 2145-8F4 or the
SAN Volume Controller 2145-8F2 node in the rack:
1. Stand at the front of the rack and place the back of the node onto the support
2. Slide the node fully into the rack.
3. Repeat this procedure for each SAN Volume Controller 2145-8F4 or the SAN
Connecting the SAN Volume Controller 2145-8F4 or the SAN
Volume Controller 2145-8F2 to the 2145 UPS-1U
Before you connect the SAN Volume Controller 2145-8F4 or the SAN Volume
Controller 2145-8F2 node to the 2145 uninterruptible power supply-1U (2145
UPS-1U), review the restrictions that exist between the two systems.
Note: To make the SAN Volume Controller cluster more resilient to power failure,
Before you begin this task, see the user's cable connection table, which is provided
in the IBM System Storage SAN Volume Controller: Planning Guide and is also
available at http://www.ibm.com/storage/support/2145. Use this table to identify
the 2145 UPS-1U to which this SAN Volume Controller 2145-8F4 or SAN Volume
Controller 2145-8F2 is to be connected.
Perform the following steps to connect the SAN Volume Controller 2145-8F4 or the
SAN Volume Controller 2145-8F2 to the 2145 UPS-1U:

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 UPSs 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.
