Replacing a Defective Power Supply
This section describes how to replace the following:
Ÿ
AC Power Supply
Ÿ
-48 Volt DC Power Supply.
The 8265 can accommodate up to four modular load-sharing AC or DC power supplies.
Note: When replacing a power supply, you must leave enough supplies running at all times to satisfy the
requirements of installed modules. If removal of a defective, but still functioning, power supply will
not cause a power deficit in the 8265, you can remove the faulty supply without losing power to a
module or modules. Before attempting to remove a power supply from the chassis, enter the
SHOW POWER BUDGET command to display current power conditions for the 8265.
