1 Intel Express 10/100 Fast Ethernet Switch
Flow Flow control. Lights whenever too much traffic is
entering on a port. When this happens, the switch's
buffers fill and it's forced to back pressure the
traffic out to the segment for retransmission. This
allows the switch's buffers to clear before the
segment retransmits the traffic. See page 73 for a
description of flow control.
100 Speed. Lights when a 100BASE-TX device is
connected to the port. The LED is off when a
10BASE-T device is connected.
Link
Link. When solid, indicates a connection is
established. If the Link LED is off, check for loose
cable connections. Also, make sure you're using the
correct type of cable, either straight-through or
crossover. See page 8 for more information.

Management status LEDs

Management status LEDs provide information about the overall
operation of the switch and its SNMP management components.
Simple Network Management Protocol. Always
SNMP
on, indicating the built-in SNMP agent is working.
Management. Blinks on at regular intervals as the
Mgmt
SNMP agent is polled for updated information.
Power. Indicates the status of the power supply. The
Power
LED is normally on. It may remain off for a few seconds
during the power-on self-test.
Fault. Indicates that the switch has detected a
Fault
problem. It may remain on for a few seconds during the
power-on self-test. If this indicator blinks or remains lit
after self-test, there's a problem with the switch.
See Chapter 4 for troubleshooting information.
