Connecting power to the BCM system
The BCM system is available in North American and International versions. Ensure that the power
supply is correct for your location. The BCM200 and BCM400 systems have standard power
supplies and redundant power supplies that adjust automatically to the required voltage.
Follow this procedure to check the voltage and wiring, and to power up the system.
To connect power and wiring
1 Check all wiring before connecting power to the BCM units.
2 Connect the BCM main unit power cord to an electrical outlet that is a non-switchable,
third-wire ground AC outlet.
If you use a power bar, plug the power cords into the power bar and connect the power bar to
the AC outlet.
3 Connect the BCM expansion unit power cord to an electrical outlet that is a non-switchable,
third-wire ground AC outlet.
Warning: Leakage currents
Service personnel must be alert to the possibility of high leakage currents becoming
available on metal system surfaces during power line fault events near network lines.
These leakage currents normally safely flow to protective earth ground through the power
cord.
System shutdown: You must disconnect the media bay module cables from the system
before disconnecting the power cord from a grounded outlet.
System startup: You must reconnect the power cords to a grounded outlet before
reconnecting the cables to the media bay modules.
Warning: Connecting power
Always connect power to the BCM main unit and expansion unit before you reconnect the
cabling to the front of the units.
Danger: Do not fasten power supply cords
Do not fasten the BCM main unit or expansion unit power supply cords to any building
surface.
