Business Communications Manager System Startup
This chapter describes initial system startup procedures for the Business Communications
Manager.
The Business Communications Manager and expansion unit 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
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 Business
Communications Manager system 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 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.
