Note
The System LED area provides general, static information about the LEDs only. The display does not
change to reflect the current state of the LEDs.
Note
8-port HP ProCurve 1810G switches may be PoE Powered Devices (PD) through port 1 only. (24-port
ProCurve 1810G switches do not support PoE). The 8-port switches provide an additional PD LED,
which turns On if it is receiving PoE power through port 1.

Note
The LED modes area provides general, static information about the LEDs. The display does not change
to reflect the current state of the LEDs. The physical LED Mode behavior is described below.
On the switch, the active LED mode is indicated by three LEDs:

If the LED Mode button is not pressed for 10 minutes, the LED mode automatically returns to Activity
mode.
If Green Mode is enabled (see
the LED Mode button temporarily restores the LED Mode feature.
System LEDs—You can point to the System LEDs area to view information about the switch
LEDs.
Switch LEDs include the following:
• Power (Green)
– On— The system is being powered by AC/DC power or Power-over-Ethernet (PoE).
– Blinking—Power from the PoE port is lost or insufficient. The LED continues to blink
until PoE is restored or the system is reset.
– Off—The system is powered by the external power adapter.
• Fault (Orange)
– Blinking—A fault has occurred, other than during self-test.
– On—Failure during self-test.
– Off—The switch is operating properly.
• Locator—When on, the switch is in Locate Mode so that it can be physically located. This
mode can be enabled using the Web interface. See
LED Mode—Each port has two LEDs. The function of the right LED (called the Mode LED)
changes depending on the LED mode selected for the switch. Use the LED Mode button on
the switch to select a mode (Act, FDx, Spd).
You can move your cursor over the LED Mode area to view a description of the LED modes.
Act—Activity. When Act mode is selected, the Mode LED for each port will blink upon port
activity.
FDx—Full Duplex. When FDx mode is selected, the Mode LED for each active port will
illuminate only when the port is operating in full-duplex mode.
Spd—Speed. When Spd mode is selected, the Mode LED for each active port will illuminate
when the port is operating at 100 Mbps (blinking) or 1000 Mbps (solid on), or will be off when
the port is operating at 10 Mbps.
