Cabling
This section provides instructions for connecting devices (such as hubs, servers,
personal computers, and workstations) to the switch. Remember these tips when
connecting cables:
•
Avoid stretching or bending the cables excessively.
•
Avoid routing the cables near potential sources of electromagnetic
interference, such as motorized devices and fluorescent lights.
•
Avoid trip hazards by routing the cables away from aisles and other areas
where people walk. If such routes cannot be avoided, use floor cable covers or
similar material to secure and protect the cables.
•
Be sure that the cables connected to the switch are supported so that the cable
connectors are not excessively strained.
•
For Token-Ring, use a Category 3 or better UTP cable or a 150 ohm STP or
STP-A cable with an impedance-matching balun at each end.
•
For Fast Ethernet, use a Category 5 or better UTP cable.
Connecting the Fast Ethernet Ports
The Fast Ethernet ports use standard or crossover UTP-5 copper cables. The
maximum cable length is 100 m (328 feet).
1. Insert the modular RJ-45 jack from either end of a standard or crossover UTP-
5 cable into one of the Fast Ethernet connectors.
2. Connect the other end of the cable to:
•
another CrossFire 8730 Fast Ethernet port (using a crossover UTP-5 cable)
•
100/10 MB Ethernet adapter (using a crossover UTP-5 cable)
•
100/10 MB Ethernet switch or hub port (using a standard UTP-5 cable)
Connecting Devices to the Token-Ring Ports
If you will not be using building wiring (in-the-wall cables) to connect the device
to the switch, perform the following steps. If you will be using building wiring,
follow the steps in section "Connecting Devices to the Token-Ring Ports Using
Building Wiring" on page 30.
Follow the steps below to connect one or more devices to the Token-Ring ports on
the switch:
