Troubleshooting
This chapter includes troubleshooting and replacement procedures for the
VSU-5000 power supply module, cooling fan and dual-port Ethernet module.
Power Supply
The standard VSU-5000 includes a single power supply module.
NOTE:
The VSU-5000 is provisioned with one of two different power supply
module types. Replacement procedures for both types are covered in this section.
Fault Indication
If the power supply module fails, an audible alarm will sound and the green LED
status indicator on the power supply subsystem extinguishes. The audible alarm
automatically silences after a preset time. Contact your customer service
representative to obtain a replacement for the defective power supply module.
WARNING:
To ensure that the power supply ventilation system continues to
work correctly,
do not remove the defective power supply module until you
have a replacement unit available
.
