Connecting the SAN Volume Controller 2145-CF8 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.

Before you begin

Notes:
  • 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.
  • When connecting to the 2145 UPS-1U, use only the power cable assembly, part number 31P1294, that was supplied with the node. Power cable assemblies that were supplied with previous SAN Volume Controller models do not work with the 2145-CF8 model because there are two power cables in the bundle for the 2145-CF8 model. The correct part is differentiated by the blue tape that binds the cables together.

Before you begin this task, see the completed customer's cable-connection table, which is described in the IBM SAN Volume Controller Planning Guide and can be downloaded from the www.ibm.com/support.

Use the information in this table to identify the 2145 UPS-1U unit to which this node is to be connected.

To connect the system to the 2145 UPS-1U:

Procedure

  1. At the back of the SAN Volume Controller 2145-CF8 node, plug the power cables of the combined power and serial cable assembly into the power connector  2 , as shown in Figure 1.

    •  1  Fibre Channel ports
    •  2  Power connector
    •  3  Serial connector
    •  4  Ethernet ports
    •  5  Main-power connector
    •  6  Communication port
    •  7  Load-segment 2 receptacle
  2. Place the other end of the power cables into the load-segment 2 receptacles  7  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.
  3. Plug the signal cable into the serial connector  3  located on the SAN Volume Controller 2145-CF8 node.
  4. Place the other end of the signal cable into the communication port  6  on the 2145 UPS-1U.

Results

The SAN Volume Controller 2145-CF8 power is now connected to the 2145 UPS-1U.
