9. At the back of the 2145 UPS-1U, connect the SAN Volume Controller power cable to load segment 2

receptacle (3 in Figure 310 on page 279). If applicable, install the power cable-retention bracket

(shown in Figure 309 on page 279).

Note: The 2145 UPS-1U is intended to maintain power on a single SAN Volume Controller node

until data can be saved to the local hard disk drive. Only SAN Volume Controller nodes can be

plugged in to the 2145 UPS-1U or else the SAN Volume Controller cluster malfunctions. You must

attach only one SAN Volume Controller to the 2145 UPS-1U, and nothing else.
