Ethernet and LED status
Four 10/100/1000 megabits per second (Mbps) Ethernet ports are side by side on the 
canister. They are marked as 1 and 3 on the left and 2 and T on the right. Each port has two 
LEDs, and their status values are listed in Table 13-2. Although ports 1 - 3 are available for 
management and internet Small Computer System Interface (iSCSI) purposes, the T port is 
strictly dedicated to the technician actions (initial and emergency configuration by local 
support personnel).

Serial-attached SCSI ports
Two 12 Gbps serial-attached SCSI (SAS) ports are side by side on the canister with indicator 
LEDs below them. They are numbered 1 on the left and 2 on the right. Each port is 
associated with one green and one amber LED indicating its status of the operation, as listed 
in Table 13-3.

Node canister status LEDs
There are three LEDs in a row in the upper middle position of the canister that indicates the 
status and the functionality of the node (see Table 13-4).

LED Color Meaning
Link state Green It is on when there is an Ethernet link.
Activity Amber It is flashing when th ere is activity on the link.
LED Meaning
Green Link is connected and up.
Orange Fault on the SAS link (disconnected, wrong speed, errors).
Position Color Nam e State Meaning
Left Green Power On The node is started and  active. It might not be safe to 
remove the canister. If the fault LED is off, the node is an 
active member of a cluster or candidate. If the fault LED 
is also on, node is in service state or in error, preventing 
the software to start.
Flashing 
(2 Hz)
Canister is started and in standby mode.
Flashing
(4 Hz)
Node is running power-on self-test (POST).
Off No power to the canister or it is running on battery.
Middle Green Status On The node is a member of a cluster.
Flashing 
(2 Hz)
The node is a candidate for or in a service state.
