Fibre Channel LEDs
The Fibre Channel LEDs indicate the status of the Fibre Channel ports on the SAN Volume Controller 2145-DH8 node.
The SAN Volume Controller 2145-DH8 uses two light-emitting diodes (LEDs) per Fibre Channel port, which are arranged one above the other. The LEDs are arranged in the same order as the ports. Figure 1 shows the location of the LEDs.

LEDs
- 1 Link speed LEDs
- 2 Link activity LEDs
The following table lists the link status values for the Fibre Channel LEDs.
| Top LED (link speed) | Bottom LED (link activity) Flashing indicates I/O activity. |
Link status |
|---|---|---|
| Off | Off | Inactive |
| Off | On / Flashing | Active 2 Gbps |
| Blinking | On / Flashing | Active 4 Gbps |
| On | On / Flashing | Active 8 Gbps |
Note: To accommodate the different
Fibre Channel speed ranges, LEDs are effectively OFF=slow, FLASHING=medium,
and ON=fast.
