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.
