Connecting UTP Cables
The
fixed
RJ45
front
panel
ports
are
10/100/1000
Mbps
ports
and
have
internal
crossovers.
When
connecting
a
workstation
to
these
ports,
use
a
straight
‐
through
cable.
When
connecting
networking
devices
to
these
ports,
such
as
a
bridge,
repeater,
or
router,
use
a
crossover
cable.
