a.
Determine a suitable cable route from the redundant ac-power switch to the power distribution
units.
b. Route the main input power cable of the redundant ac-power switch to the specified power
distribution unit, and connect it.
c. Route the backup input power cable of the redundant ac-power switch to the specified power
distribution unit, and connect it.
d. Verify that the redundant ac-power switch power cables are tidy. Ensure that they do not obstruct
other equipment and are tied in place where necessary.
11. Test the redundant ac-power switch before connecting it to the 2145 UPS-1U, using MAP 5340 in the
IBM System Storage SAN Volume Controller 2145 Troubleshooting Guide .
