		Switch 208/224 Description
		Front of the Switches
	LEDs
LED	State	Meaning
Power (green)	Off	The switch is not receiving power.
	On	The switch is receiving power.
Fault	On	The switch has failed its self-test after being powered on or reset.
	Flashing	An incorrect transceiver has been installed in the transceiver slot, or a connected
	Slowly*	RPS has a failure. The corresponding LED (transceiver port or RPS) will also flash.
	Off	The normal state. Indicates that there are no fault conditions on the switch.
RPS	Off	This switch is not receiving power from the HP J2962A Redundant Power Supply
		(RPS).
	On	This switch is receiving power from the connected RPS.
	Flashing	An error has occurred on the RPS connected to the switch. See the documentation
	Slowly*	provided with the RPS for troubleshooting.
Expansion Slot		The behavior of these four LEDs depends on the module inserted into the Expansion
Module LEDs (4)		Slot. See the module manual for a description of these LEDs.
	On	Indicates that an optional module is installed in the expansion slot in the back of the
		switch. Any expansion modules installed into the switch use the port 1 circuitry to
(port 1 disabled)		communicate with the network through the switch. Therefore, when a module is
		installed, the port 1 RJ-45 connector is can not be used to connect a network device.
	Off	The port 1 RJ-45 connector is available to be used for connecting a network device
		to the switch.
100 Mbit/s Ports
A or B	Off	No active network cable is connected to the port. For port B, could indicate that
		there is no transceiver installed. Could also indicate that the port has been disabled
		through the switch console or HP AdvanceStack Assistant (port configuration
		changes require a Switch Management Module to be installed).
	On	During the first 3 seconds after an active network cable is connected or after a
		switch reset, indicates the port is enabled and receiving a link beat signal . After 3
		seconds, On continuously indicates a saturated network segment on the port.
	Flickering	Indicates activity on the port.
	Flashing	This condition will only occur on the 100 Mbit/s port B (the transceiver port), if an
	Slowly*	incorrect transceiver is installed in the slot.
100	On	The port is operating in 100 Mbit/s mode.
Fdx	On	The port is operating in full-duplex mode.
	Off	The port is operating is half-duplex mode, or is not operating.
