Appendix B. SAN Volume Controller 2145-4F2
The SAN Volume Controller 2145-4F2 node has some unique controls and
indicators, rear panel indicators, hardware components, and connectors.
Preparing your SAN Volume Controller 2145-4F2 environment
Before installing the SAN Volume Controller 2145-4F2, you must prepare the
physical environment.
Input-voltage requirements
Ensure that the following requirements for each SAN Volume Controller 2145-4F2
node are met:
Voltage Frequency
200 to 240 V single phase ac 50 or 60 Hz
Power requirements for each node
Ensure that the following power is available for each SAN Volume Controller
2145-4F2 node. The power that is required depends on the node type, the
uninterruptible power supply (UPS) type, and whether the redundant ac power
feature is used.
Components Power requirements
SAN Volume Controller 2145-4F2 + 2145
UPS-1U
420 W
One SAN Volume Controller 2145-4F2 + one
2145 UPS
760 W
Two SAN Volume Controller 2145-4F2 nodes
+ one 2145 UPS
1120 W
For each redundant ac power switch, add 20 W to the power requirements.
Circuit breaker requirements
Ensure that the following circuit breaker requirements are met:
v The 2145 UPS-1U has an integrated circuit breaker and does not require
additional protection.
v Each 2145 UPS is connected to a separate branch circuit, which includes a
UL-listed 15 A circuit breaker.
