Connecting The San Volume Controller 2145-4F2 To The 2145 Ups - IBM 2145-8F4 Installation Manual

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

Connecting the SAN Volume Controller 2145-4F2 node to the 2145 uninterruptible
power supply (2145 UPS) requires that you first review the restrictions that exist
between the two systems.
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
2145-4F2s.
Attention: Do not connect two nodes to the same pair of 2145 UPSs. Both nodes
are lost in the event that a power failure occurs on both of those 2145 UPSs.
Note: You must install 2145 UPSs in pairs. There must be at least two 2145 UPSs
Before you begin this task, refer to the user's cable connection table in the IBM
System Storage SAN Volume Controller: Planning Guide to identify the 2145 UPS to
which this SAN Volume Controller 2145-4F2 is to be connected.
Perform the following steps to connect the SAN Volume Controller 2145-4F2 to the
2145 UPS:
1. At the back of the SAN Volume Controller 2145-4F2, plug a power cable into

Use caution when working in any potential safety hazardous situation that is
not covered in the safety checks. If unsafe conditions are present, determine
how serious the hazards are and whether you can continue before you correct
the problem.

2145-4F2s. 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 UPSs.
