Perform the following steps to install the SAN Volume Controller 2145-8F2 or the
SAN Volume Controller 2145-8F4 node in the rack:
1.
Stand at the front of the rack and place the back of the node onto the support
rails, as low in the rack as possible.
2. Slide the node fully into the rack.
The node snaps into place.
3. Repeat this procedure for each node that needs to be installed.
Tip: If you have available space, leave a 1U space between each node to
improve the air circulation in the rack.
Connecting the SAN Volume Controller 2145-8F2 or the SAN Volume
Controller 2145-8F4 to the 2145 UPS-1U
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:
1. 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
