Equipment and Rear Access Cable Installation
NOTE
:
It is important to carefully follow the procedures in this section to ensure
that the bay will accommodate all of the cables and that the backplane
cover will fit properly.
NOTE
:
It is recommended that ONLY designated Lucent Technologies cables be
used.
NOTE
:
This section is best performed if each procedure such as "DS1 Cable
Installation - Rear Access" is performed on every shelf in the bay before
proceeding to the next procedure.
NOTE
:
Circuit packs must not be installed at this time.
NOTE
:
All cables, except power and the optical fibers, are connected to the
DDM-2000 OC-3 backplane. In some configurations of Releases 11 and
13, there is a cable to be connected between the fronts of two OLIU circuit
packs and another that is connected to the front panel of specific DS3 cir-
cuit packs. Also, in some Release 11 and 13 configurations, an extended
front cover, such as used with form 4 shelves, must be used to provide
clearance wherever these front-installed cables are used.
NOTE
:
The locations of all backplane plugs and jacks are shown in Figure 2-1.
NOTE
:
The cabling for the maximum capacity of six DDM-2000 OC-3 rear-access
shelves in a bay is shown in Figure 2-2 or Figure 2-3 (depending on the bay
arrangement).
NOTE
:
Cables are to be installed from the bottom shelf in the bay toward the top.
The cable installation procedure described in this section should be fol-
lowed for maximum utilization of the bay cable ducts.
NOTE
:
Cable assembly options are listed in Tables 2-1 through 2-5. Connector
pinouts are provided in Figure 2-4.
NOTE
:
Cable brackets should be installed as required.
