Maintaining the PTX5000 AC Power System
Maintaining the PTX5000 AC Power System
Purpose
For optimum performance, verify the condition of the power distribution units (PDUs), power supply modules (PSMs), AC power cords, and grounding cables.
Action
On a regular basis:
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 PTX5000 Chassis Grounding Cable and Lug Specifications and Site Electrical Wiring Guidelines.
Check the status of the PDUs by issuing the
show chassis environment pducommand.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 PTX5000 AC Power Distribution Unit LEDs and PTX5000 AC Power Supply Module LEDs.
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:
content_copy zoom_out_mapuser@host> show chassis alarms
For a list of possible alarm messages, see Troubleshooting the PTX5000 Power System.
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 powercommand .content_copy zoom_out_mapChassis Power Input(V) Used(W) Total Power 3810 PDU 0 3810 PSM 0 Input 1 54 331 PSM 1 Input 1 54 661 PSM 2 Input 1 54 1432 PSM 3 Input 1 54 1386Issue the
