Appendix B: UTP Cabling
The performance of a switching system depends on high quality connections. Poor quality or
poorly installed or maintained cabling can diminish system performance. Consult with the local
code officials orAPC technical support prior to any installation.
UTP copper cabling
Switching systems utilize unshielded twisted pair (UTP) cabling. The KVM switch supports three
types of UTP cabling:
• CAT5 UTP (4-pair) high performance cable consists of twisted pair conductors, used primarily
for data transmission. The twisting of the pairs gives this cable some immunity from the
infiltration of unwanted interference. CAT5 cable is generally used for networks running at
100 or 1000 Mbps.
• CAT5E (enhanced) cable has the same characteristics as CAT5 cable but is manufactured to
higher standards.
• CAT6 cable is manufactured to higher standards than CAT5E cable. CAT6 has higher
measured frequency ranges and significantly better performance requirements than CAT5E
cable at the KVM server module frequencies.
Wiring standards
There are two supported wiring standards for 8-conductor (4-pair) RJ-45 terminated UTP cable:
EIA/TIA 568A and EA/TIA 568B. These standards apply to installations utilizing CAT5, CAT5E,
and CAT6 cable specifications. The switching system supports either of these wiring standards. See
Table B.1 for details.
