12 12000E IP Broadband Loop Carrier Installation Instructions IPD1-A2-ZZ40-20
2 Connect the ground wire to a frame ground. Ground wire connection can
vary from location to location though 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 12000E
may be used to power the chassis; only one terminal block is required for
operational purposes. The two terminal blocks on the 12000E are
independent feeds. Chassis power is supplied by only one terminal block
at a time; the second supply is a backup. Likewise, the two terminal
blocks do not load-share. Each terminal block must be supplied with
adequate amperage to run the chassis independently.
CAUTION:
Two identical terminal blocks are provided on the 12000E chassis to
allow for redundant 48V DC power sources. Each power source to be
connected with the 12000E must be equipped with a disconnect
device such as an On/Off switch, or, an appropriately rated circuit
breaker must be installed on each power circuit to be used. Hazardous
voltages will not be removed from the 12000E until all power sources
have been either turned off or disconnected from the chassis.
