Starting the system

The BCM1000 and BCM1000e are each powered through an ac outlet. The voltage required depends on the geographical location of the units.

All systems are initially set at the factory, based on the intended destination. You must check that the voltage and wiring are correct for you system before you connect any of the units to the power source. Incorrect power settings result in equipment damage.

Note: Newer standard power supplies (BCM 2.5 hardware), and all redundant power supplies can auto-select voltage. Ensure you are aware of what type of power supply your system has.

Read the following warnings. You must protect yourself and the Business Communications Manager units from possible electrical shocks.

Warning: Use only qualified persons to service the system.

The installation and service of this unit must be performed by service personnel with the appropriate training and experience. Service personnel must be aware of the hazards of working with telephony equipment and wiring. They must have experience in techniques that minimize any danger of shock or equipment damage.

Danger: Electrical shock hazards

Electrical shock hazards from the telecommunications network and ac mains are possible with this equipment. To minimize risk to service personnel and users, the BCM1000 and BCM1000e, if there is one, must be connected to an outlet with a third wire ground. In addition, all unused slots must have blank faceplates installed. The covers on all units must be in place at the completion of any servicing.

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 via the power cord.

System shutdown: You must disconnect the media bay module cables, MSC and network cables from the front of the units before disconnecting the power cord from an earthed.

System startup: You must reconnect the power cords to an earthed outlet before reconnecting the media bay, MSC and network cables to the front of the unit.
