StatusDescriptionItem
Green = The switch temperature is normal.
Blinking orange (blinks every 1.6 seconds) = An over temperature condition has
been detected. This is a Fault condition indicating elevated internal temperatures.
The Fault LED will blink simultaneously.
Blinking orange = (blinks every 0.8 seconds) = This indicates an alert condition
indicating critical internal temperatures. The Fault LED will blink simultaneously.
Fan:
Green: All fans are operating normally.
Blinking orange (blinks every 1.6 seconds) = One of the unit’s fans has failed. The
switch Fault LED will be blinking simultaneously.
Blinking orange = (blinks every 0.8 seconds) = One of the unit’s fans has failed
and the switch is in an overtemp condition. The switch Fault LED will be blinking
simultaneously.
Test Status:
Green = The switch self-test and initialization are in progress after the switch has
been power cycled or reset. The switch is not operational until this LED goes off.
The Self-Test LED also comes on briefly when you “hot swap” a transceiver into the
switch; the transceiver is self-tested when it is hot swapped.
Blinking orange = A component of the switch has failed its self-test. The status LED
for that component, for example an RJ-45 port, and the switch Fault LED will blink
simultaneously.
Off = The normal operational state; the switch is not undergoing self-test.

Press the button to step from one mode to the next. The current mode setting is
indicated by the Mode select LEDs near the button.
Mode select LED:
Link = Indicates that the port LEDs are displaying link information. If the port LED
is on, the port is enabled and receiving a link indication from the connected device.
If the port LED is off, the port has no active network cable connected, or is not
receiving link beat or sufficient light. Otherwise, the port may have been disabled
through the switch console, the Web browser interface. If the port LED is blinking
1 simultaneously with the Fault LED, the corresponding port has failed its self-test.
Act = Indicates that the port LEDs are displaying network activity information.
FDx = Indicates that the port LEDs are lit for ports that are in full-duplex mode. Off
indicates half duplex.
Spd = Indicates that the port LEDs are displaying the connection speed at which
each port is operating. If the port LED is off, the port is operating at 10 Mb/s. If
the port LED is flashing, the port is operating at 100 Mb/s, and if the port LED is
on continuously, the port is operating at 1000 Mb/s.
Usr = Indicates the port is displaying customer-specified information.
Blinking green = Data transfer between the switch and a USB device is occurring.Auxiliary LED5
Green = The USB device is connected to the switch but no data transfer operation
is occurring.
Blinking orange (blinks every 1.6 seconds) = Indicates an error condition. The
switch Fault LED will be blinking simultaneously. There is a hardware fault associated
with the USB device or the USB connector on the switch.
Blinking orange = (blinks every 0.8 seconds) = Indicates an alert condition. The
switch Fault LED should not be blinking simultaneously. An alert error occurred in
the USB operation that is not caused by a hardware fault, such as a file transfer
error.
Off = Indicates that no USB device has been inserted, or that the inserted USB
device cannot be recognized, or that no command file can be found on the inserted
USB device.
