4.14 Checking Power at Optical/Tributary Shelf
This procedure is used for verifying the power connections to the Optical/Tributary shelf.
DANGER:
Use caution when working on the power strip at the top of any shelf to avoid personal
injury, damage to equipment, or both. Avoid touching terminals or uninsulated
conductors.
Step Task
1 Set the PDP fuses for the installed shelves to the ON position. See Figure 4-45 [p. 4-64] for
the appropriate circuit breaker, if necessary.
2 Remove the plastic cover over the power strip on the shelf station interface area (SIA).
3 Connect the negative DMM test lead to the GA ground terminal on the SIA power strip, and
connect the positive DMM test lead to the MAIN A voltage terminal. See Figure 4-48
