ANSI Hardware Installation Manual
14.5.1
This section includes information about the power distribution frame, external
ground, and power cable routing.
14.5.1.1
The 7360 ISAM FX-8 shelf is powered through two redundant branches A, and B, in
a three-wire configuration provided by the PDF.
The 7360 ISAM FX-8 operates with a nominal voltage level of −48 Vdc supplied by
battery power sources in the CO or cabinet.
14.5.1.2
The standard rack provides three frame ground points with two located on top of the
rack. The safety ground conductor used must be a green-yellow insulated cable (UL
60950-1 2nd Edition and CAN/CSA C22.2 NO. 60950-1-07 compliant).
14.5.1.3
Power cables are routed from the PDF to the rack using cable channels overhead
and are connected at the input terminal block inside the 7360 ISAM FX-8 shelf.
To minimize interference, Nokia recommends that you route power cables using
separate channels for signal and power cables.
Keeping a distance of 4 in. (10 cm) between signal and power cables is advisable
where it imposes no practical problems.
Crossing of signal cables with power cables and parallel routing over short distances
is acceptable.
14.5.2
The 7360 ISAM FX-8 is designed to be used as stand-alone equipment. It is
equipped with a −48 Vdc power distribution unit with terminal block.
The power distribution terminal block is located at the bottom left of the shelf and is
covered with a plastic safety cover.
