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.
