Mode Depending on the mode selected, displays the following: network activity information, whether
the port is configured for Full Duplex operation, maximum speed operation, or whether network
errors are occurring on the port. See "LED Mode Select Button and Indicator LEDs" below for
more information.

Meaning
A module is installed in the switch module slot corresponding to the letter and the module
is undergoing or has passed self test. This also occurs when you install a module when
the switch is powered on ("hot swap").
A module is not installed in the switch module slot corresponding to the letter.
The module status LED flashes very briefly when a module is being hot swapped. If the LED
flashes for a prolonged time, the module in the slot corresponding to the letter has failed
self test or encountered some other fault condition. See chapter 4, "Troubleshooting" for
a more information.
Indicates the port Mode LEDs are displaying network activity information.
Indicates the port Mode LEDs are lit for ports that are in Full Duplex Mode.
Indicates the port Mode LEDs are lit for ports that are operating at their maximum possible
link speed -- for any Gigabit-capable connection, that would be 1000 Mbps; for the 10/100-
TX ports and 100-FX ports, that would be 100 Mbps.
Switch Module LEDs
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) 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, HP ProCurve Manager, or other network management tool.
†
The port has failed self test. The switch Fault and Self Test LEDs, and appropriate
module status LEDs will flash simultaneously.
