Connecting Power to the PTX5000 High Capacity Wye AC PDUs

Firmware Version (MCU1) 03.04

If you set the ampere switch in the wiring compartment

incorrectly, the AC power cord might overheat. Setting the ampere switch

incorrectly might also cause the site circuit breaker to trip.

The system software gets the system power configuration from

the PDU and displays it in the output of the

command. Depending on the setting, the system software limits the system

configuration (FPCs and PICs) to keep the power demand within the

maximum output power available from the PDU.

In a redundant system with two PDUs, the PDUs share the load. If

the ampere switch setting of one PDU is lower than the other, Junos OS

reduces the rating of the other PDU to the lower value.

Repeat the procedure for the other High Capacity Delta AC PDU.
