10 Gbps Ethernet-activity LEDs. The green activity LED is on while data is
being sent over the link.
Fibre Channel LEDs
The Fibre Channel LEDs indicate the status of the Fibre Channel ports on the SAN
Volume Controller 2145-CG8 node.
The SAN Volume Controller 2145-CG8 uses two Fibre Channel LEDs per Fibre
Channel port, which are arranged one above the other. The LEDs are arranged in
the same order as the ports.
The Fibre Channel LEDs indicate the following link status:
Top LED (link speed)
Bottom LED (link activity)
Blinking indicates I/O
activity.
Link status
Off Off Inactive
Off On / Blinking Active 2 Gbps
Blinking On / Blinking Active 4 Gbps
On On / Blinking Active 8 Gbps
Note: To accommodate the different Fibre Channel speed ranges, LEDs are effectively
OFF=slow, BLINKING=medium, and ON=fast. This means that 4Gbps is indicated
differently on different models.
Ac, dc, and power-supply error LEDs
The ac, dc, and power-supply error LEDs indicate whether the node is receiving
electrical current.
Figure 44 shows the location of the SAN Volume Controller 2145-CG8 ac, dc, and
power-supply error LEDs.
Each of the two power supplies has its own set of LEDs.
