Overview
The DC version of the PDU has eight dual-post lug power connections, four positive and four negative. A
single dual-post lug grounding connection is also provided. The HDVC version of the PDU uses one Andersen
SAF-D-GRID(R) connector per power supply.

Fan Modules

The chassis can accept up to eight fan modules (N20-FAN5). A chassis must have filler plates in place if no
fan will be installed in a slot for an extended period.

LEDs

There is one LED indication of the fan module's operational state. See
details.

Buttons and Connectors

No buttons or connectors are on a fan module.

Power Supplies

Different power supplies are available to work with the AC (UCSB-PSU-2500ACPL or N20-PAC5-2500W)
or DC (UCSB-PSU-2500DC48) versions of the chassis.
When configured with the Cisco UCS 6324 Fabric Interconnect, only the following power supplies are
supported: UCSB-PSU-2500ACDV dual-voltage supply and UCSB-PSU-2500DC48 -48V DC power supply.
