Optional DC Hot Swappable Power Supplies
The DC power system is designed to allow the storage system to be installed with
Telco system hardware installations. It consists of two 350-watt hot-pluggable
power supplies, each with independent DC power cables and cooling fans. It
provides the enclosure with "N+1" redundant power with Telco hardware. Each
power supply cables directly with your DC power feed system.

The DC power supply has the same user features to that of the AC Hot
Swappable Power Supplies described on the previous page.
NOTE:
The DC system must be installed in a restricted access location, in
accordance with intent of the National Electrical Code. A restricted access
location is defined as an area intended only for qualified or trained
personnel only. Access should be controlled by key lock or access card.
Each power supply has a special cable connector that plugs into the face of the
power supply and mechanically connects to your DC feed system. Refer to the
Installation chapter for cabling procedures.
