Intel 10/100 manual Management status LEDs, Link

C H A P T E R 1 Intel Express 10/100 Fast Ethernet Switch

Use these communications settings when accessing the built-in Console Manager application. See page 16 for more information.

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.

100Speed. 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.

SNMP Simple Network Management Protocol. Always on, indicating the built-in SNMP agent is working.

Mgmt Management. Blinks on at regular intervals as the SNMP agent is polled for updated information.

Power Power. Indicates the status of the power supply. The LED is normally on. It may remain off for a few seconds during the power-on self-test.

Fault Fault. Indicates that the switch has detected a 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.
