Meaning
The normal operational state; the switch is not undergoing self test.
The switch self test and initialization are in progress after you have power cycled or
reset the switch. The switch is not operational until this LED goes off. The Self Test LED
also comes on briefly when you "hot swap" a module into the switch; the module is self
tested when hot swapped.
A component of the switch has failed its self test. The status LED for that component,
for example a fan, and the switch Fault LED will flash simultaneously.
Indicates that the port Mode LEDs are displaying network activity information.
Indicates that the port Mode LEDs are lit for ports that are in Full Duplex Mode.
Indicates that the port Mode LEDs are lit for ports that are operating at 100 Mbps.
A module is installed in the switch module slot and that the module is undergoing or
has passed self test.
A module is not installed in the switch module slot.
The module in the slot has failed self test or is not installed properly. The switch Fault
LED, and the Self Test LED may be flashing simultaneously. If the Module Status LED is
flashing by itself, a different module type has been hot swapped into the slot without
the switch being reset. See "Hot Swapping Switch Port Modules" on.
The cooling fans are operating normally.
One or more of the cooling fans have failed. The switch Fault LED will be flashing
simultaneously.
Switch Port Module LEDs
Meaning
Indicates the port is enabled and receiving a link beat signal (for the twisted-pair ports),
or a strong enough light level (for the fiber-optic ports) from the connected device.
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.
