ELS100-24TX

Connecting Network Cables

Network cable must comply with the following requirements:

Category 3 or 5 Unshielded Twisted Pair (UTP) for ports running
10Base-T

Category 5 UTP for ports running 100Base-TX

Maximum length for UTP connections: 100m (328 ft.)

RJ-45 Connector

The 10Base-T/100Base-TX ports use RJ-45 connectors. Figure 2-5
shows an RJ-45 connector being inserted into a port.

10Base-T/100Base-TX Ports

The 10Base-T/100Base-TX ports use RJ-45 connectors for connection to
10Base-T or 100Base-TX network segments or end-stations. These UTP
connections meet the requirements of ISO 8877, specified by 10Base-T,
Section 14 of the IEEE 802.3 specification. The ports are wired with the
MDI-X function implemented. Workstations or servers can be connected
to the ELS100-24TX switch using standard straight-through wired cables.

For connections to hubs or other switches, a crossover cable may be
necessary (refer to the “MDI/MDI-X Crossover Cable Wiring” section in
Appendix A). See Table A-2 for 10Base-T/100Base-TX connector pin
assignments.
