Node canister LEDs
Each node canister has three LEDs that provide status and identification for the
node canister.
The three LEDs are located in a horizontal row near the upper right of the canister
1
. Figure 18 shows the rear view of the node canister LEDs.
Note: The reference to the left and right locations applies to canister 1, which is
the upper canister. The port locations are inverted for canister 2, which is the lower
canister.

The on status indicates that the node is active, that
is, it is an active member of a clustered system.
When the node is active, do not remove it.
v
The off state indicates there is no power to the
canister or the canister is in standby mode. These
conditions can cause the off state:
– The main processor is off and only the service
processor is active.
– A power-on self-test (POST) is running on the
canister.
– The operating system is loading.
v
The flashing status indicates that the node is in
candidate state or service state. It is not able to
perform I/O in a system. When the node is in
either of these states, it can be removed. Do not
remove the canister unless directed by a service
procedure.
