To replace the node canister, perform the following steps:
1. Read the safety information to which "Preparing to remove and replace parts"
on page 79 refers.
2. Confirm that you know which canister to replace. Go to "Procedure:
Identifying which enclosure or canister to service" on page 47.
3. Record which data cables are plugged into the specific ports of the node
canister. 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 for each canister.
5. Grasp the handle between the thumb and forefinger.
Note: Ensure that you are opening the correct handle. The handle locations
for the node canisters and expansion canisters are slightly different.
Handles for the node canisters are located in close proximity to each other.
The handle with the finger grip on the right removes the upper canister ( 1 ).
The handle with the finger grip on the left removes the lower canister ( 2 ).
