2.

3.

Step Action

1.

Insert one to three ELF DSX modules into the chassis. Secure each module to the chassis faceplate with two screws (provided).

Mount the ELF DSX with four screws (#12 or M6, both sets are provided).

®

Attach a 14 AWG ground wire with a ring lug to the 8-32 ground stud on the rear panel. Connect the opposite end to a ground point on the rack.

®

2-3

4.

5.

Attach in/out (I/O) cables (at the rear for chassis systems; at the front for TFA DSX modules used in chassis). Connectors are labeled. Use cable ties and the tie-down bar to manage the cables.

Make cross-connects at the front of the panel. If required, secure jumpers to the front tie-down bar using cable ties inserted through the slots in the bar and then wrap the tie around the jumpers.

Use four, suitable panhead screws to secure DSX bracket to wall.

Screws are not included.

Mount the ELF DSX in bracket using two M3 screws provided.

The away-facing surfaces of the mounting ears on the module are stripped of paint to ensure a good electrical ground. For grounding, use the ring lug and star lockwasher provided along with a #14

AWG (min.) copper wire.

For TFA Wire-Wrap DSX modules, a. Wire-wrap in/out (I/O) cables to the left of the patch area. Use cable ties and the tie-down bar to manage cables.

b. Make cross-connects at the right of the patch area. Again, use cable ties and tie-down bar to manage cables.

The example below shows network element 1 (NE 1) cross-connected to NE 6.

ONITORING

To monitor the OUT signal from an ELF DSX module, plug one end of a single patch cord into the MON port and the other end into the monitoring equipment. The MON port connection is nonintrusive.

P

ATCH

A

ND

R

OLL

Patching maintains a circuit by temporarily cross-connecting to back-up equipment so that technicians can repair or test the lines of the permanent connection. Patching and rolling allows a circuit to be moved from an existing facility to a new or spare facility, including new permanent crossconnects.

NOTE

If you use a dual patch plug, remember to twist the plug on one end of the cord so that it is reversed (i.e., turned upside down) from the other end.

124317-5 A0

Step Action

1.

Patch B to spare facility C. Insert patch cords in C, then in B.

Remove the cross connects between the A and B facilities.
