EX4400 Switches Hardware Overview

  
Rack or Cabinet

Verify that the rack or cabinet meets the minimum requirements for installing the switch.

  

Plan rack or cabinet location, including required space clearances.

   

Secure the rack or cabinet to the floor and building structure.

   
Cables

Acquire cables and connectors:

  • Determine the number of cables needed based on your planned configuration.

  • Review the maximum distance allowed for each cable. Choose the length of the cable based on the distance between the hardware components being connected.

Note:

The Ethernet cables to connect to the RJ-45 network ports on EX4400-24P and EX4400-48P switches provide 90-W power over 4-pair wire. To ensure that the cables do not exceed the rated temperature and ampacity and to ensure proper operation, the cables must meet the following specifications related to deployment, temperature rise, category, IEEE, UL, NEC, and local electric codes:

  • 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.

   

Plan the cable routing and management.
