| 5, 6 | Power connector | Green or red | Green |
Green: power present, operating normally. Off: Power not present, system is not powered on. Red: Power not present, power supply alarm configured. |
| 7 | 100/100BASE-T traffic | Green or amber | Off, solid green, or blinking green |
Off: no link, port not configured. Solid green: link present. Blinking green: data sent or being received. Alternating green and amber: Link Fault. Solid amber: port is disabled and is not forwarding data. This condition can occur because of improperly terminated Ethernet cables. Specific to MRP ring ports: if both ends of a chain of devices are terminated back to the two designated MRP ring ports on a switch, the forwarding port displays blinking green and the blocked port displays solid green. This combination of LED light status signifies the ring is closed or in a healthy state. If both ring ports display blinking green, the MRP ring is open or in a faulty state. Note: After a port is newly connected or
reconfigured, this LED is amber for approximately 30
seconds while STP checks the switch for possible
loops.
