Edition One
XC1000 Service
Prepare cables to be attached to connectors in the following XC1000 locations:
-
Power-distribution shelf
-
Main backplane
-
Main distribution board
-
ACP I/O distribution board #1 (optional)
-
ACP I/O distribution board #2 (optional)
-
Busy-out controller (optional)
These telephone-line and cable-termination locations are described in
sections 2.6.1 through 2.6.5.
2.6.1 Power-Distribution Shelf
The cable for the –48 Vdc power input is connected to the XC1000 on the
power-distribution shelf. The power cables can reach the power-distribution
shelf either from the top or from the bottom, depending on whether the cables
are run through the ceiling or the floor. Use the following procedure to
ensure correct cabling to the power-distribution shelf:
1. Plan for the following current and power levels:
-
30 amperes maximum at –48 Vdc for a single cabinet and 45
amperes maximum for a dual cabinet
-
Maximum power requirement, 1500 watts per cabinet
-
Sufficient number of 115-Vac outlets near the XC1000 site for
peripheral devices and test equipment
2. Make sure to provide 45 ampere, –48 Vdc power if you plan to expand
to a dual cabinet in the future. This planning will eliminate having to
expand the current capacity later.
3. Install the power cables using one of the following methods:
-
Drop an insulated power cable for power, return, and ground
with strain relief to reach the power-distribution shelf shown in
Figure 2-5. Although wire size depends on several installation
factors, Octel recommends using a 6-AWG or larger conductor.
A 1
1
⁄
4
-inch (3.2cm) conduit can be used to enclose these
conductors.
-
Pull the cable or cables through a 1
1
⁄
4
-inch (3.2cm) conduit
under the raised floor, and route the conduit up the back or side
of the XC1000 to reach the power-distribution shelf.
2.6.2 Main Backplane
The main backplane is located on the back of the XC1000 frame and
provides the data and control-bus connections for all of the cards contained
in the logic bay, including the CPU, file cards, monitor card, and DLCs.
The main backplane also provides the connections between the TICs in the
logic bay and the CO lines or trunks. The CO trunk cables are connected
to the main backplane using 25-pair male Amphenol-type connectors.
