= A component of the switch has failed its self-test. The status
LED for that component and the switch Fault LED will blink
simultaneously.
Displays port link information, network activity information, whether the
port is configured for full-duplex operation, or the speed of the connection,
depending on the LED Mode view selected.

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.

The HP ProCurve 2800 Series switches use a single LED for each port. The operation of this LED
is controlled by the LED Mode select button, and the current setting is indicated by the LED
Mode indicator LEDs near the button. Press the button to step from one view mode to the next.
The LED Mode button has the following indicator lights:
• If the Link (Lnk) indicator LED is lit, each port LED displays link information for the
associated port. If the port LED is in Link mode and it is blinking, the port has failed its self
test. The Fault and Self-Test LEDs will be blinking simultaneously.
• If the Activity (Act) indicator LED is lit, each port 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 port LEDs light for those ports that are
operating in full duplex mode.
• If the Speed (Spd) indicator LED is lit, the port LEDs behave as follows to indicate the
connection speed for the port:
— OFF = 10 Mb/s
— Flashing = 100 Mb/s (the flashing behavior is a repeated on/off cycle once every 0.5 sec.)
— ON = 1000 Mb/s
3.3.1 Reset Button
The reset button is used to reset the switch while it is turned on. This action clears any temporary
error conditions that may have occurred and executes the switch self-test.
