DC Power Source, Power Connection, and Grounding
Requirements
The server power source and connections must meet the following requirements.
Note -
The DC version of the server must be installed in a restricted-access location. According
to the intent of the U.S. NEC, a restricted-access location is an area intended for qualified or
trained personnel only and has access controlled by a locking mechanism, such as a key lock or
an access card system.
Caution -
The DC power source must be reliably grounded. The server chassis must be
grounded with the power supply ground pins or with the chassis ground studs. It is acceptable to
have both grounds connected.
Caution -
You must restrict the connection of the server to the DC power source to minimize
the possibility that transient energy will appear on the main input to the equipment. The DC
power source must be in the same premises as the server. The server cannot be in one building
with the power source in another building.
Caution - An accessible two-pole disconnect device must incorporated in the fixed wiring.
