Connecting UTP Cables
The RJ45 fixed front panel ports (1 through 48) of the C1H124-48 are 10BASE-T/100BASE-TX
compliant and have internal crossovers. The RJ45 fixed front panel ports (1 through 24) of the
C1G124-24 are 10BASE-T/100BASE-TX/1000BASE-T compliant 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.
To connect a twisted pair segment to either the C1H124-48 or C1G124-24, refer to
Figure 3-7
and
proceed as follows:
1. Ensure that the device connected to the other end of the segment is powered ON.
2. Connect the twisted pair segment to the device by inserting the RJ45 connector
on the twisted
pair segment into the desired RJ45 port (for example, Port 1
).

Connecting a Twisted Pair Segment to the Device
NOTE: All RJ45 front panel ports on the C1H124-48 and C1G124-24
support
Category 5 Unshielded Twisted Pair (UTP) cabling with an impedance between 85 and
111 ohms. Category 3 cable may be used if the connection is going to be used only for
10 Mbps.
