Removing a PTX5000 PDU DC Power Cable
Each PDU has eight input power trays. Each input power tray is hot-insertable and
hot-removable, and weighs 1.6 lb (0.7 kg).
To remove a DC power cable:
1. Switch off the customer site circuit breakers to the input power tray that contains the
DC power cable being removed.
2. Make sure that the voltage across the DC power source cable leads is 0 V and that
there is no chance that the cables might become active during the removal process.
Verify that the –48 V 120 A LEDs on the PDU faceplate are off.
3. Switch the circuit breaker for the input power tray on the PDU faceplate to the off
position (O).
4. Loosen the captive screws that secure the input power tray to the PDU.
5. Remove the input power tray from the PDU.
