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 shielded RJ-45 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.
