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.
DC Power Supply
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.
