Cabling
Cajun P120 modules include the following types of ports (according to the speed
and standard they support): 10Base-T, 100Base-TX , 100Base-FX, 10/100 Mbps
auto-negotiating, 1000Base-SX and 1000Base-LX. To interconnect Cajun P120
switches with copper wire crossed cables are required.
• The maximum UTP cable length connected to a 10/100 Mbps port operating as
10Base-T, is 100 m (328 ft.).
• A UTP Category 5 cable may be co nnected to any 100Base-TX port, via an
RJ-45 connector. The maximum UTP cable length connected to a 100Base-TX
port, or a 10/100 Mbps port operating as 100Base-TX, is 10 0 m (328 ft.).
• A fiber-optic cable may be connected to any 100Base-FX port, via a pair of SC
connectors. The maximum fiber cable length connected to a 100Base-FX port is
412 m (1,352 ft.) when operating in half duplex, and 2 km (6,562 ft.) when
operating in full duplex.
Appropriate cables are available from your local supplier.
*1000BASE-LX over Multimode fiber requires a special Patch cord cable w hich you
can obtain from your local cable supplier.
