This object is a set of system LED indications. The first six octets are defined as system LED. The first two octets are currently unused and must be set to zero. The third octet indicates the power LED. The fourth octet indicates the console LED. The fifth LED is RPS (Redundancy Power Supply) LED. The sixth LED is Master(Stacking Master Device) LED. For the byte range form 7 to 8, it reflect the MGMT port. Every two bytes are presented to a port. For the byte range from 9 to 56, it reflect the 1~24FE ports. Every two bytes are presented to a port. For the byte range from 57 to 64, it reflect the 25~26GE Combol ports. Every four bytes are presented to a port. The byte range from 57 to 60, it reflect copper ports. The byte range from 61 to 64, it reflect fiber ports. For the byte range from 65 to 72, it reflect the 27~28GE Combol ports. Every four bytes are presented to a port. The byte range from 65 to 68, it reflect copper ports. The byte range from 69 to 72, it reflect fiber ports. Every two bytes are presented to a port. The first byte is presented as the Link/Activity LED. The second byte is presented as the Speed LED. Power LED: 01 = fail/error/non existence 02 = work normal Console LED: 01 = Console LED OFF 02 = Console LED ON RPS LED: 01 = RPS LED OFF 02 = RPS LED ON Master LED: 01 = Master LED OFF 02 = Master LED ON Link/Activity LED : The most significant bit is used for blink/solid: 8 = The LED blinks. The second most significant bit is used for link status: 1 = link fail. 2 = link pass. Speed LED : 01 = 10Mbps. 02 = 100Mbps. 03 = 1000Mbps. The remaining bytes are currently unused and must be 0.
