Figure 49. LEDs on the node canisters
Verify that you are reseating the correct node canister and that you use the correct
canister handle for the node that you are reseating. Handles for the node canisters
are located next to each other. The handle on the right operates the upper canister.
The handle on the left operates the lower canister.
1. Verify the clustered-system status LED on the node canister. If it is
permanently on, the node is active. If the node is active, no reseating is
required.
2. Verify that you have selected the correct node canister and verify why you are
reseating it. Go to "Procedure: Identifying which enclosure or canister to
service" on page 196.
3. Grasp the handle between the thumb and forefinger.
4. Squeeze them together to release the handle.
5. Pull out the handle to its full extension.
6. Grasp the canister and pull it out 2 or 3 inches.
7. Push the canister back into the slot until the handle starts to move.
8. Finish inserting the canister by closing the handle until the locking catch clicks
into place.
9. Verify that the cables were not displaced.
10. Verify that the LEDs are on.
