24 Port Interface Card
C613-03023-00 REV P
Good quality, data-grade cables should be used for all cables. Transition cables
must be made from paired cable with an overall foil shield. Metalised
backshells must also be used. Poor quality cables limit the maximum speed or
the maximum length of the cable, or both.
It is very important that cables do not degrade the EMC emission standards of
the switch, router, or PIC (e.g., FCC, CISPR). The cable foil shield must be
connected to the AMPLIMITE metalised backshell with a 360 degree ferrule. In
addition, on specified cables, a clip-on cable ferrite must be attached to the
cable at the AMPLIMITE end, no more than 25 mm from the rear of the
backshell of the AMPLIMITE connector. Contact your authorised Allied Telesis
distributor or reseller for a list of approved ferrites.
Use the following pin wiring diagrams when constructing transition cables for
each physical interface standard.
