RJ-45 Cable Specifications for EX4300 Switches

 

EX4300 switches have 10/100/1000/2500/5000/10000BASE-T Ethernet network ports that use various types of copper network cables. You must use cables that conform to IEEE 802.3-2012 specifications to connect to those ports. Table 1 lists the specifications of the cables that you must use.

CAT 6 cables are defined to perform at frequencies up to 250 MHz and are sensitive to alien crosstalk. To use such cables to connect to the ports, you must ensure that the cable installation is tested and is certified for 500 MHz as per TIA TSB-155 standard.

Note

The Ethernet cables that you use to connect to the RJ-45 network ports on EX4300-48MP and EX4300-48MP-S switches and provide 95 W power over 4 pair wire must meet the following specifications related to deployment, temperature rise, category, IEEE, UL, NEC, and local electric codes to ensure proper performance and to not exceed rated temperature and ampacity of cables:

  • The cables must be rated for IEEE 802.3 BT, TIA standards, and UL-LP.

  • The cables must follow NEC 725.144 article and local electric code.

  • The operating temperature of the cable must be rated at 15° C more than the ambient temperature.
