Mode Select Button and Indicator LEDs

To optimize the amount of information that can be displayed for each of the
switch ports without overwhelming you with LEDs, the Switch 1600M and
2400M use a Mode LED for each port. The operation of this LED is controlled
by the Mode Select button, and the current setting is indicated by the Mode
indicator LEDs near the button. Press the button to step from one mode to the
next.

Meaning
Indicates the port is enabled and receiving a link beat signal (for the twisted-pair ports),
or a strong enough light level (for the fiber-optic ports, if installed in the Switch 1600M)
from the connected device.
One of these conditions exists:
• no active network cable is connected to the port
• the port is not receiving link beat or sufficient light
• the port has been disabled through the switch console, the web browser interface,
or HP TopTools.
If the Activity (Act) indicator LED is lit, each port Mode LED displays
activity information for the port—it flickers as network traffic is received
and transmitted through the port.
If the Full Duplex (Fdx) indicator LED is lit, the port Mode LEDs light for
those ports that are operating in full duplex.
If the 100 Mbps (100) indicator LED is lit, the port Mode LEDs light for
those ports that are operating at 100 Mbps.
