Switch Overview

Switch Hardware Features

LED Mode Select Button and Indicator LEDs

To optimize the amount of information that can be displayed for each of the

switch ports, the ProCurve 1810G-24 Switch uses a Mode LED for each port.

The operation of this LED is controlled by the LED Mode Select button on the

switch panel, and the current selection is indicated by the mode indicator

LEDs near the button. Press the button to change from one mode to the next.

■ 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.

■ When the FDx (full duplex) indicator LED is on, the port Mode LEDs turn

on for those ports that are operating at full duplex.

■ If the Speed (Spd) indicator LED is lit, the port LEDs behave as follows

to indicate the connection speed for the port:

• Off = 10 Mbps

• Blinking = 100 Mbps (the blinking behavior is a repeated on/off cycle

once every 1.6 sec.)

• On = 1000 Mbps

Reset Button

This button is used to reset the switch while it is powered on. This action clears

any temporary error conditions that may have occurred and executes the

switch self test.
