Powering Up Your 4000E BLC

CAUTION:

Turn your DC power source(s) OFF until you have completed connection of the 4000E as outlined in the following sections.

1.Connect a ground wire to￿￿￿￿￿￿￿￿￿￿￿￿￿￿￿the 4000E: Line up the 2-hole terminal lug of your ground wire with the two holes on the small, unpainted section on the back of your chassis. Secure the terminal lug to the chassis with two #10-32 screws.ProcedureDo not operate the 4000E without a ground connection.

2.Connect the Ground Wire to a Frame Ground. Ground wire connection can vary from location to location, although typically all equipment in a Central Office is grounded to a common copper bus.

3.Select a Terminal Block. Either terminal block on the back of the 4000E may be used to power the chassis; only one terminal block is required for operational purposes. The two terminal blocks on the 4000E are independent feeds. Chassis power is supplied by only one terminal block at a time; the second supply is a backup. The two terminal blocks do not load-share; each terminal block must be supplied with adequate amperage to run the chassis independently.
