Note:
The Version B RLX switches can be enabled or disabled by the MPU if the
jumpers are in place. But the switches' jumper settings themselves (FFhex or 7Fhex for
the Channel Blocking Idle switch; –130V or ±130V for the Line Power switch) cannot
be overridden by the MPU.
Note:
The B1 RLX factory default setting for the Channel Blocking Idle Code jumper is
7Fhex; the B1 RLX factory default setting for the Line Power jumper is –130 VDC. The
B2 RLX+ factory default setting for the Channel Blocking Idle Code jumper is FFhex;
the B2 RLX+ factory default setting for the Line Power jumper is –130 VDC. A missing
jumper in the Channel Blocking Idle Code causes a default to FFhex. A missing jumper
in Line Power causes a default to no voltage output.
Note:
If the Line Power jumper is set, it must also be enabled, which is done through
software.

3. Refer to your work order to determine which RLX slots are to be used. Slot locations are
illustrated in Figure 525-4. Chassis slots 1-1 through 7-4 correspond to DS1 signals 1
through 28 as shown in Table 525-1.

4. Align the RLX module with the slots and slide it into the chassis. Use the ejector to press the
RLX module into the backplane connector until it is properly seated. If there is excessive
resistance to insertion, remove the unit and check for improper alignment or obstructions.
5. Observe the front panel LED indicators as shown in Figure 525-5 and verify that each LED
operates as specified in the initial start-up test.
• If the STATUS LED is green following self-test, continue to Step 5.
• If the STATUS LED is red, the RLX has failed self-test diagnostics. Remove and then
reinsert the RLX and then wait while the RLX again performs self-test diagnostics. If
the STATUS LED turns red at the end of the second self-test, the RLX is defective.
Remove and replace the RLX, and then repeat Steps 1 through 5.
6. Press the LMPTST switch on the APU and verify that all indicators light yellow.
• If Yes, continue to Step 7.
• If No, replace the RLX module and go to Step 1.
Note:
An MPU must be present for a Version B RLX lamp test. The MPU does not need
to be present for a Version A RLX lamp test.
7. If the Span Power (in the Version A RLX) option or Line Power (in the Version B RLX)
option is selected in Step 1, measure DC voltage and DC current being supplied to the
repeater.
