Equipment and Rear Access Cable Installation
Issue 9 October 1998

NOTE
:
The cables are connectorized at the DDM-2000 OC-3 end and must be
wire-wrapped at the DSX end. Cables are wire-wrapped at the DSX-1 end
as shown in Table 2-6.
Procedure
1. Obtain the DS1 cables per Table 2-1 and note which function group each
cable is to be used with.
2. Remove the front, rear, and DS1 cable chamber covers from the
DDM-2000 OC-3 shelf, if this has not already been done.
NOTE
:
The covers must be installed later to assure compliance with EMI require-
ments and proper cooling.
3. Remove the DS1 cable chamber clamps from the DS1 chamber.
4. Connect the function group B cables at the DDM-2000 OC-3 end, carefully
matching the correct connector with the appropriate backplane plugs as
shown in Figure 2-8.
NOTE
:
All backplane cables must route underneath the rear cover mounting
assemblies racks to allow the backplane cover to fit after the cable installa-
tion. The rear cover mounting assemblies racks are removable.
NOTE
:
Retainers must be in place on the DS1 backplane pins.
NOTE
:
The DS1 backplane plug identifications are stenciled to the right of the
plugs.
NOTE
:
The cables must be attached so that the wired side of the connector
attaches to the left column of pins in the retainer area. Each retainer
accommodates two DS1 cable connectors.
5. Dress the DS1 cables to ensure that the cables will fit properly in the DS1
cable chamber.
6. Repeat Steps 1 through 5 for the function group A cables.
7. Repeat Steps 1 through 5 for the function group C cables.
