Table 1-2. Switch and Transceiver Port LEDs
Port LEDs State Meaning
Link On Indicates the port is enabled and receiving a link indication from the connected device.
Off One of these conditions exists:
• no active network cable is connected to the port
• the port is not receiving link beat or sufficient light
• the port has been disabled through the switch console, the web browser interface,
or HP TopTools.
Blinking If the LED is blinking simultaneously with the Fault LED, the corresponding port has
failed its self test.
The LED can blink by itself (no Fault LED blinking) for the transceiver ports. This occurs
when a transceiver is installed and the switch has not yet been reset. Transceivers can
be installed in the slots while the switch is powered on, but the switch must be reset
to initialize the transceiver and make it operational.
Mode Displays network activity information, or whether the port is configured for Full Duplex operation, or
maximum link speed operation, or is experiencing network events requiring operator intervention
depending on the mode selected. See “Mode Select Button and Indicator LEDs” below for more
information.
