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.
Do not operate the 4000E without a ground connection.
Procedure
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.
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.
