Status/Activity LEDs

12.1 LEDs

The following table explains the Ethernet Backplane SwitchModule 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.

12.2 Ports

The Ethernet Backplane SwitchModule front panel ports use crossover ports with RJ-45 connectors (see the figure at right). The X that follows the port number indicates a crossover port.

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
