This object is a set of system LED indicators. The first four octets are defined as a system LED. The first LED is a power LED. The second LED in the stacking module is a master LED but in the chassis is a status LED. The third LED is a console LED. The fourth LED is an RPS (Redundancy Power Supply) LED. The other octets are the logical port LED (following dot1dBasePort ordering). 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.

system LED: 01 = fail/error/non existence. 02 = work normal.

link/activity LED : The most significant bit is used for blinking/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 four remaining bits are currently unused and must be set to 0.

Note: For the DGS-3700, the first five octets are defined as the system LED. The first LED is the power LED. The second LED is the console LED. The third LED is the RPS (Redundancy Power Supply) LED. The fourth LED is the management port LED. The fifth LED is the fan LED.

For the DGS-3200-10 and DGS-3200-16, the first three octets are defined as the system LED. The first LED is the power LED. The second LED is the console LED. The third LED is the RPS (Redundancy Power Supply) LED. For the DGS-3200-24, the first three octets are defined as the system LED, the definition of the first three octets is the same as the DGS-3200-10 and DGS-3200-16, the fourth LED is the SD card LED. The following description is for the SD card LED: 01 = SD card is not present. 02 = SD card is present. 03 = fails to read/write SD card. 04 = read/write SD card successfully.
