Installing DC Power Entry Modules
The C150 has six power supply slots at the front-bottom of the chassis (
Figure 8-2
). The slots accept
either AC power supplies (PSUs) or DC Power Entry Modules (PEMs). Dell Force10 does not support
the use of a combination of AC and DC.
•
If you select DC, the C150 requires at least one DC PEM for operation, but Dell Force10 recommends a
one-plus-one redundancy configuration. Those DC PEMs are inserted in slots 0 and 2.
•
To protect against high-voltage shock, install a power supply blank (CC-C-BLNK-PWR) on all unused
power supply slots.
NOTE:
The C150 DC Power Entry Module does not support PoE line cards.
Recommended Normal Operating Conditions
Redundancy
For full facility redundancy, install two DC PEMs. Each PEM must be attached to an independent power
source with a dedicated circuit breaker sized in accordance with your local building and electrical safety
codes.
Cable and Connector Requirements
You must provide your own cables to connect to a remote power source (a circuit breaker panel, for
example) in your equipment rack or facility. Cables must be sized to meet the following criteria:
