1. Using a #2 Phillips screwdriver, remove the 5 screws on the back of the Cage that
attach the fan pack.
2. Slowly pull the fan pack straight back by inserting your fingers in the slots on both
sides of the fan pack. Wait for the fans to stop spinning before setting aside.
3. Slowly insert the new fan pack to ensure proper seating of the connector.

attach the fan pack.
2. Insert a finger in the slot on the left side of the fan pack and slowly pull the fan
pack out. If you are hot-swapping the fan pack, wait for the fans to stop spinning
before setting it aside.
3. Pull the failed PSU (the one with the red LED displaying) straight out until it clears
the chassis.
4. Insert the replacement PSU and push it firmly until the connector seats. A green
LED is displayed.

Replacing a Blade Switching or Direct Connect BackPack
If you are replacing a Blade Switching or Direct Connect BackPack, or upgrading from
a Direct Connect BackPack to a Blade Switching BackPack, do the following:
1. Shut down all Blades in the Cage.
2. Disconnect power from the BackPack.
3. Slide all eight Blades out approximately one inch.
4. Remove the fan pack per the instructions above.
5. Label and remove all cables attached to the BackPack.
6. Remove the BackPack from the rear of the Cage by removing the 2 screws
(located inside the Cage near the top of the BackPack) with a #2 Phillips
screwdriver. Make sure to save these screws. (See Figure 58.)
CAUTION: The fan pack is designed to be hot-swappable in that it can be
removed and replaced by an authorized technician with the system
power plugged in. However, be sure the new fan pack is replaced and
operating within one minute to prevent overheating the system. Never
leave a Cage with Blades running without a fan pack installed for more
than two minutes.
