You might need to remove the enclosure from the rack as part of a service procedure.

Before you begin

CAUTION:

To avoid any hazard from the rack tipping forward when devices are installed, observe all safety precautions for the rack into which you are installing the device.

CAUTION:

The weight of this part or unit is between 18 and 32 kg (39.7 and 70.5 lb). It takes two persons to safely lift this part or unit. (C009)

Removing the enclosure

1. Shut down both canisters in the enclosure by using the service assistant. Follow the steps in Procedure: Powering off a node canister.
2. Use the Power LED indicators on the canisters to confirm that it is safe to remove the enclosure from the enclosure.
3. Record which data cables are plugged into the specific ports on the rear of the canisters and the enclosure.
   The cables must be inserted back into the same ports after the replacement is complete; otherwise, the system cannot function properly.
4. Disconnect the data cables that are connected to the canisters and the enclosure.
5. Disconnect the power cables from the power supplies.
6. Disconnect the Cable Management Arm (CMA) from the inner CMA brackets on the rear corners of the enclosure. Do not disconnect the outer brackets that connect the CMA to the rack.
7. Open the two latches at the front corners of the enclosure, and, by using two persons, slide the enclosure out of the rack.

Replacing the enclosure

8. With the help of two persons, lift the chassis until the back of the enclosure is aligned with the front of the rack rails.
9. Slide the enclosure between the rails.
   When fully inserted, the enclosure latch on each front corner of the enclosure engages with the blue hook on the vertical rail of the rack.
10. Connect the CMA to the inner CMA brackets on the rear corners of the enclosure.
11. Connect the data cables to their original locations on the enclosure and interface adapters.
12. Connect the power cables to the enclosure.
