	Green	The Switch is powered-up and
		operating normally
	Yellow	The Switch has failed its Power On Self
		Test. This occurs if any of the ports fail
		during power-up.
	Off	The Switch is not receiving power.

	If there is evidence of a problem, see “Solving Problems Indicated by
	LEDs” on page 32.

Choosing the	All of the ports on the front of the Switch 1100 are configured as MDIX
Correct Cables	(cross-over). If you want to make a connection to another MDIX port, you
	need a cross-overcable. Most of the 10BASE-T and 100BASE-TX ports on
	3Com devices are MDIX-only. Many ports on workstations and servers are

configured as MDI (straight-through). If you want to make a connection to an MDI port, you need to use a standard straight-throughcable. This is illustrated in Figure 11.
