3Com 5000 quick start Port Status or Activity Indicates LED State, 10BASE-T

10 COREBUILDER® 5000 SWITCHMODULE QUICK START AND REFERENCE

11.1 LEDs

The following table explains the 10BASE-T port status or activity LED blink sequences:

Port Status or Activity		Indicates
	LED State
Green	On	Port is enabled and link is OK.
	Blinking	Link failure or waiting for network
		connection.
	Off	Port or port functions are disabled.
Yellow	On	Heavy traffic activity on the port.
	Blinking	Normal traffic activity on the port.

11.2 Ports

10BASE-T SwitchModules use the following port types:

■The 12-Port, 20-Port, and 24-Port 10BASE-T SwitchModules use crossover ports with RJ-45 connectors.

CoreBuilder 5000 10BASE-T modules use crossover ports. This means that if you connect a 10BASE-T SwitchModule port to another CoreBuilder 5000 10BASE-T module port, you must use a crossover cable.

■The Ethernet Telco SwitchModule uses two standard female Telco connectors with 12 ports per connector for a total of 24 ports.

The following illustrations show these SwitchModules. The X that follows the port numbers indicates a crossover port.
