Color State
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 34.
All of the ports on the front of the Switch 3300 XM, SM, TM and MM are
configured as MDIX (cross-over). If you want to make a connection to
another MDIX port, you need a cross-over cable. 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-through cable. This is illustrated in Figure 14.
