The status LED for that component and the switch Fault LED will blink simultaneously. 6 Port LEDs Green - Displays port link information, network activity information, whether the overlaid port is configured for full-duplex operation, or the speed of the connection, with the depending on the LED Mode view selected. port number 7 LED Mode 4 green Link = Indicates that the port LEDs are displaying link information. If the view LEDs 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 flashing2, the port is operating at 100 Mb/s, and if the port LED is on continuously, the port is operating at 1000 Mb/s. 8 T/M Green - ports 21 to 24 or 45 to 48 only For the dual-personality ports, indicates which connector is enabled: T = Indicates the 10/100/1000Base-T RJ-45 port is enabled. M = Indicates the mini-GBIC port is enabled. 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. 3.3 HP ProCurve 2800 Series LEDs and Buttons 27

= 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.

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

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
