7 Cabling and Technology Information
This appendix includes switch connector information and network cable information for cables
that should be used with the Hewlett Packard Enterprise switches.
NOTE: Incorrectly wired cabling is a common cause of problems for LAN communications.
Hewlett Packard Enterprise recommends that you work with a qualified LAN cable installer for
assistance with your cabling requirements.
