Choosing the
Correct Cables
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
