Switch Module/Port LEDs
The following LEDs are located on the modules themselves or fixed ports
depending on which switch chassis you have, one pair for each port.
LED Mode
Select
(3 green LEDs)
Act
Indicates the port Mode LEDs are displaying network activity information.
FDx
Indicates the port Mode LEDs are lit for ports that are in Full Duplex Mode.
Spd
Indicates the port Mode LEDs are displaying the connection speed at which each port is
operating:
• if the port Mode LED is off, the port is operating at 10 Mbps.
• if the port Mode LED is flashing, the port is operating at 100 Mbps.
• if the port Mode LED is on continuously, the port is operating at 1000 Mbps.
!
Indicates that specific error packets are being detected on the port. In this mode, the Mode
LED for the port will flash briefly for each error packet that is detected, for example CRC
errors or late collisions.
1
The flashing behavior is an on/off cycle once every 1.6 seconds, approximately.

LED
State
Meaning
Link
On
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.
Off
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, ProCurve Manager, or other network management tool.
Flashing
1
The port has failed self test due to hardware failure or because the port type
requires newer software in order to be recognized. The switch Fault, Self Test
LEDs, and appropriate module status LEDs will flash simultaneously. The Fault
LED will flash only for hardware failure.
Fast
Flashing
2
Port security has disabled the port.
Mode
Depending on the mode selected, displays the following: network activity information, whether
the port is configured for Full Duplex operation, port connection speed, or whether network
errors are occurring on the port. See “LED Mode Select Button and Indicator LEDs” below for
more information.
1
The flashing behavior is an on/off cycle once every 1.6 seconds, approximately.
2
The fast flashing behavior is an on/off cycle once every 0.8 seconds, approximately.
