92Technical Specs Technical Specs 93WiringHorizontal cables should be terminated using the T568A pin/pair assignments, “or, optionally, per [T568B] if necessary toaccommodate certain 8-pin cabling systems”. Despite this instruction, many organizations continue to implement T568Bfor various reasons, chiefly associated with tradition (T568B is equivalent to AT&T 258A).

This feature eliminates the need for crossovercables, making obsolete the uplink/normal ports and manual selector switchesfound on many older hubs and switches and greatly reducing installation errors.Avoid heavy weights on the cableUse shielded connectionsUse appropriate clampsAvoid heat sourcesRespect bending radiuswww.blusensnetworks.com
