The normal state. Indicates that there are no fault conditions on the switch.
An incorrect transceiver has been installed in the transceiver slot. The transceiver port

or sufficient light. For port A, it could indicate that there is no transceiver installed. Could
also indicate that the port has been disabled through the switch console, the web agent
interface, or HP TopTools.
This condition will only occur on the 100 Mbps port A (the transceiver port), if an
incorrect transceiver is installed in the slot.

The port is operating in 10 Mbps mode.
Indicates the port is enabled and receiving a link beat signal from the connected device.
No active network cable is connected to the port, or the port is not receiving link beat
