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 31.
Fiber optic cables should be fitted with SC connectors.
Both the RJ45 ports on the front of the Switch 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 10.
