Connecting the SAN Volume Controller 2145-4F2 to the 2145 UPS

Connect the SAN Volume Controller to the 2145 UPS 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.

Each SAN Volume Controller 2145-4F2 of a pair must be connected to a different 2145 UPS. Each 2145 UPS can support up to two SAN Volume Controller 2145-4F2 nodes.

Attention: Do not connect two nodes to the same pair of 2145 UPS units. Both nodes are lost in the event that a power failure occurs on both of those 2145 UPS units.

Note: You must install 2145 UPS units in pairs. There must be at least two 2145 UPS units per cluster. A cluster can contain no more than eight SAN Volume Controller 2145-4F2 nodes. Also, ensure that each 2145 UPS of a pair is connected to a separate electrical input power source (if possible) to reduce the chance of input power failure at both 2145 UPS units.

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, to identify the 2145 UPS to which this node is to be connected.

Click the Plan/upgrade tab. Under Sizing/Capacity, click SAN Volume Controller planning. Click your language to view the Planning Guide abstract. The charts and tables are located under the Related information heading.

Perform the following steps to connect the SAN Volume Controller 2145-4F2 node to the 2145 UPS:

At the back of the SAN Volume Controller 2145-4F2 node, as shown in Figure 1, plug a power cable into the power connector .

DANGER
You have already switched on the 2145 UPS. The output sockets of the 2145 UPS are live.
Place the other end of the SAN Volume Controller 2145-4F2 power cable into any vacant output connector on the 2145 UPS.
Place the other end of the signal cable into any vacant position on the top row of serial connectors on the 2145 UPS.
Attention: Do not plug any signal cables into the bottom row of signal cable connectors or the 2145 UPS malfunctions.

The SAN Volume Controller 2145-4F2 power is now connected to the 2145 UPS.
