When the dual power supply configuration is set at boot up, the front bezels’
Power Supply Status LED will illuminate green when both power supplies are on
and operating normally. If only one power supply is operational, the Power
Supply Status LED will be illuminated amber.
Each power supply has an AC Power Cord Module. The module has a power
cord bale incorporated into the design to secure the power cord once it has been
properly inserted. The bale prevents inadvertent disconnects.

NOTE:
Information provided here regarding the site requirements and DC
source should be used as a guide. Refer to your DC Source
documentation and local/state government requirements.
The DC power system allows the storage system to be installed with Telco system
hardware type installations. It is designed to support two 350-watt hot-pluggable
power supplies, each with independent DC power cables and cooling fans. The
base system has one power supply with an option for a second power supply. This
power system provides the enclosure with “N+1” redundant power with Telco
hardware when both power supplies are installed. Each power supply cables
directly with a DC power feed system.
DC Power Supply
Power is applied to the enclosure by pressing the power supply On/Off switch to
the “On” position. A Power On LED located on each power supply will be
illuminated indicating that DC power has been applied. The front bezels’ “Power
On” LED will also be illuminated indicating that power has been applied.
