2. Installation
Cabling
The cabling required depends on the version of the module you are installing.
CrossFire 8650 High-Speed Token-Ring UEM (UTP)
The UTP module uses standard 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 UTP-5 cable into
one of the connectors on the UEM front panel.
2. Connect the other end of the cable to either another HSTR switch port
(for example, another module) or an HSTR adapter.
3. If the default
Auto
port mode is in effect, the port will automatically open in the
appropriate
Port
or
Station
mode. Refer to Chapter 3, Console Configuration,
for details on port mode configuration.
The UTP module also supports IBM type 1 STP copper cables (150 Ohm), which
have a maximum length of 100 m (328 feet). To use an STP cable, then balluns with
an RJ-45 connector are required.
CrossFire 8651 High-Speed Token-Ring UEM (MMF)
The MMF module uses multimode 62.5/125 micron fiber cables with a maximum
cable length of 2000 m (6560 feet).
1. Connect a VF-45 optic fiber to the VF-45 connector on the front panel of the
UEM. To ensure a proper connection, it may be necessary to clean the fiber
connectors with a soft tissue dipped in alcohol.
2. Connect the other end of the cable to either another HSTR switch port (for
example, another CrossFire 8650 or 8651 UEM) or an HSTR adapter.
3. If the default
Auto
port mode is in effect, the port will automatically open in the
appropriate
Port
or
Station
mode. Refer to Chapter 3, “Console Configuration”,
for details on port mode configuration.
