194 Component Identification
Status
1
Blinking green = The cooling fan has failed. The switch Fault LED will be
blinking simultaneously.
Off = The cooling fan is operating normally.
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.
Act = Indicates that the port Mode LEDs are displaying network activity
information.
FDx = Indicates that the port Mode LEDs are lit for ports that are in Full Duplex
Mode.
Spd = Indicates that the port Mode LEDs are lit for ports that are operating
at their maximum possible link speed. For the 10/100TX ports, that is 100
Mbps.
! = Indicates that the port Mode LEDs are displaying network events that
could require operator attention, for example CRC errors or late collisions.
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.
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.
• If the Activity (Act) indicator LED is lit, each Mode LED displays activity
information for the associated port—it flickers as network traffic is received
and transmitted through the port.
• If the Full Duplex (FDx) indicator LED is lit, the Mode LEDs light for those
ports that are operating in full duplex.
• If the maximum speed (Max) indicator LED is lit, the Mode LEDs light for
those ports that are operating at their maximum possible link speed: 100
Mbps for 10/100 ports and 100-FX fiber-optic ports, and 1000 Mbps
for 100/1000Base-T or gigabit fiber-optic ports.
• If the attention (!) indicator LED is lit, each Mode LED lights briefly for
each network event that could require operator attention, for example,
late collisions or CRC errors.
