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-8 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.
