Removing and replacing the cover of a node canister

To complete a service procedure, you may need to remove and replace the cover of a node canister.

1. Remove the node canister from the control enclosure, as described in Reseating a node canister in the control enclosure.

Removing the cover

2. Place the node canister on a flat, level work surface. The release levers should be facing you and the cover should be facing upwards.
   Note: The node canister in the upper slot (node canister 1) of the control enclosure is upside-down. To access the cover, you must turn it over after you have removed it from the control enclosure.
3. Open the cover of the node canister by depressing the recessed, blue touch points on the lid ( 1 ) and sliding the lid away from you ( 2 ), as shown in Figure 1.

4. Slide the cover onto the node canister until the catch clicks and the lid edges are flush with the canister. Figure 2 shows an example.

   

   Note: Inserting the node canister into the upper slot of the enclosure requires the node canister to be inverted, so that the lid faces downwards.
