for power supply LED details.
Removing an AC Power Supply from the Cisco MDS 9509 Director
The procedure for removing an AC power supply from the Cisco MDS 9509 Director is the same for the
4000-W, 3000-W, and 2500-W power supplies, except the power cable for the 4000-W power supply is
hard wired to the power supply.
Warning
Voltage is present on the backplane when the system is operating. To reduce risk of an electric shock,
keep hands and fingers out of the power supply bays and backplane areas.
Statement 166
To remove an AC power supply from the Cisco MDS 9509 Director, follow these steps:
Step 1
Turn the power switch on the power supply to the off (0) position. Turning the power switch off also
unlocks the power supply from the chassis.
Step 2
Disconnect the power cable from the power source.
Step 3
Loosen the screw on the cable retention device and disconnect the power cable from the power supply
being removed.
Note
The AC power cable for the 4000-W power supply is hardwired and cannot be removed from the
power supply.
Step 4
Loosen the captive screw.
Caution
Use both hands to install and remove power supplies. Each Cisco MDS 9500 Series AC power
supply weighs between 22 lb (9.9 kg) and 28 lb (12.6 kg).
Step 5
Grasp the power supply handle with one hand, and slide the power supply partially out of the chassis.
Place your other hand underneath the power supply, as shown in
Figure 2-30
, and slide the power supply
completely out of the chassis.
Step 6
If the power supply bay is to remain empty, install a power supply filler panel over the opening, and
tighten the captive screw to 8 in-lb.
