• Periodically inspect the site to ensure that the grounding and AC power cords connected to the
PTX5000 are securely in place and that no moisture is accumulating near the PTX5000. To review
grounding and site wiring requirements for the PTX5000, see
and Lug Specifications" on page 164
• Check the status of the PDUs by issuing the show chassis environment pdu command.
• Make sure that the AC power cords are arranged so that they do not obstruct access to other 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.
For more information about the PDU and PSM LEDs, see
LEDs" on page 58 and
• Check the red and yellow alarm LEDs and the LCD display on the craft interface. PDU and PSM
failure or removal triggers an alarm that causes one or both of the LEDs to light and an error message
to appear on the LCD display. You can display the associated error messages by issuing the following
CLI command:
user@host> show chassis alarms
For a list of possible alarm messages, see
591.
• The power system requires an unobstructed airflow at both the front and rear of the chassis.
Periodically check the site to ensure that both the air intake at the bottom front of the chassis and
the exhaust from the PSM faceplates are unobstructed.
• To check the power usage in watts for all PDUs and PSMs, issue the show chassis power command .
