The cable must be a Category 5 shielded twisted-pair or unshielded twisted-pair (STP/UTP)
cable for 100BASE-TX, or Category 3, 4, or 5 STP/UTP cable for 10BASE-T. Consult
Table 9 for further details.

Fiber-optic cabling
Prepare a pair of fiber optic cables with SC or ST type connectors at both ends. The cable
for fiber ports must be a 62.5/125 micron fiber-optic cable for 100BASE-FX. Consult Table
9 for further details.

Uplink or MDI Function
A network of switches connected (or cascaded) together via uplink ports is termed a
“collapsed backbone.” The uplink function transforms the adjacent or indicated port into an
uplink port with a push of the button or by sliding the switch. This allows connection to
another switch or hub without preparing crossover cable. However, this is unnecessary
when either connecting directly to the uplink port of another switch or hub or when
connecting fiber ports between switches or hubs.
