Step 4
Turn the power switch to the off (0) position on the power supply that you are removing.
(See Figure 4-6.) Turning the power switch off also disengages a pawl that unlocks the power supply
from the chassis.
Disconnect the power cord from the power source.
If you are removing an 8700 W power supply from a Catalyst 6506, Catalyst 6509, or
Catalyst 6509-NEB chassis, perform the following substeps to remove the system ground wire from the
system ground posts on the power supply:
a. Loosen and remove the two M4 nuts securing the system ground lug to the two system ground posts
on the power supply. Set the two nuts aside.
b. Remove and set aside the two washers from each post.
c. Remove the system ground lug from the system ground posts and set it aside.
Loosen the screw on the cable retention device, and disconnect the power cord from the power supply
being removed.
Note
The AC power cord for the 4000 W power supply is hard wired to the power supply and cannot
be removed.
Step 5 Loosen the captive installation screw. (See Figure 4-6.)
Caution
Use both hands to install and remove power supplies. Catalyst 6500 series AC-input power supplies
weigh between 14.5 pounds (6.58 kg) and 29.0 pounds (13.15 kg).
