For optimum performance, verify the condition of the power distribution units (PDUs),
power supply modules (PSMs), DC power cables, and grounding cables.
On a regular basis:
Periodically inspect the site to ensure that the grounding and DC power cables
connected to the packet transport router are securely in place and that no moisture is
accumulating near the packet transport router. To review grounding and site wiring
requirements for the packet transport router, see
and Lug Specifications" on page 112
Check the status of the PDUs by issuing the
Make sure that the DC power cables are arranged so that they do not obstruct access
to other packet transport router components.
Routinely check the status LEDs on the PDU and PSM faceplates and the craft interface
to verify that the power system is functioning normally.
