Figure 12 R2MFC MBM RJ48 wiring array

Figure 13 on page 39 provides an overview of the process for connecting trunk wiring to the BCM

R2MFC MBMs.

Warning: Only allow qualified persons to service the BCM 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.

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 on network lines. These

leakage currents normally safely flow to Protective Earth ground through the power cord.

However, if the AC power is unplugged prior to disconnecting the cables from the front of

the base function tray, high-leakage currents available on metal system surfaces can occur.

System shutdown: You must disconnect the R2MFC MBM 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 an R2MFC MBM.

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 BCM 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.
