To allow for Switch maintenance, fiber optic cables should be the
necessary length (3 m), and the excess cabling should be bundled
near the Switch. When fiber optic cables and other interface cables
are used together, be sure to avoid applying excessive stress on the
fiber optic cables.
Always have extra fiber optic cables ready in addition to the ones in
use.

Category 3 and

The 10BASE-T, 100BASE-TX, or 1000BASE-T port on a Switch
supports Auto MDI/MDI-X functionality. If the Auto MDI/MDI-X
functionality is enabled, either a straight-through cable or a crossover
cable can be connected, regardless of the connection target.
The Auto MDI/MDI-X functionality is enabled only when
auto-negotiation is specified for a 10/100/1000BASE-T port.
The factory default setting is auto-negotiation.
If the Auto MDI/MDI-X functionality is disabled, the
10/100/1000BASE-T port of the Switch is fixed to MDI-X.
Use a straight-through cable if the port at the connection target is MDI,
and use a crossover cable if the port is MDI-X.
For information about the pin configuration of the 10/100/1000BASE-T
port when the Auto MDI/MDI-X functionality is disabled, see the
following table.
