SAN512B-6 Installation, Service, and User Guide
4 - Power supply 4
The SAN256B-6 device supports a dual-function high-voltage AC, high-voltage DC
(HVAC/HVDC) power supply assembly. This power supply converts AC or DC
input to the required DC output power required for device operation.
Each HVAC/HVDC power supply assembly provides the following power outputs
in Watts at the indicated AC and DC input rated voltages:
v 1450 W (100-120 VAC)
v 2870 W (200-277 VAC)
v 2870 W (240-380 VDC)
The following HVAC/HVDC power supply models are supported:
v Power supply model supporting nonport-side air intake (NPI). This assembly
has two fans that move the air from the nonport side to the port side of the
device.
Power supply model supporting nonport-side air exhaust (NPE). This assembly
v
has two fans that move the air from the port side to the nonport side of the
device.
Consider the following important notes about installing this power supply:
v You cannot upgrade from standard voltage AC power supplies in an existing
chassis to HVAC/HVDC power supplies. You must order a new base chassis
and the required HVAC/HVDC power supplies.
v You cannot mix HVAC/HVDC and standard voltage AC power supplies in the
same chassis. All power supplies must be the same type.
v All HVAC/HVDC power supplies installed in the device must be all either NPI
or NPE models. The airflow direction must match airflow direction of installed
fans.
