138Chapter 9 Connecting the cables

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.

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

1Check all wiring before connecting power to the BCM units.

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.

2Connect 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.

3Connect the BCM expansion unit power cord to an electrical outlet that is a non-switchable, third-wire ground AC outlet.

Danger: Do not fasten power supply cords

Do not fasten the BCM main unit or expansion unit power supply cords to any building surface.
