Chapter 8 Cabling And Technology Information; Cabling Specifications - HP Aruba 8325 Series Installation And Getting Started Manual

This chapter includes switch connector information and network cable information for cables that should be used
with the Hewlett Packard Enterprise switches.
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.

Note on 1000BASE-T cable requirements
The Category 5 networking cables that work for 100BASE-TX connections should also work for 1000BASE-T, as
long as all four-pairs are connected. But, for the most robust connections, you should use cabling that complies
with the Category 5e specifications, as described in Addendum 5 to the TIA-568-A standard (ANSI/TIA/EIA-568-A-
5).
Because of the increased speed provided by 1000BASE-T (Gigabit-T), network cable quality is more important
than for either 10BASE-T or 100BASE-TX. Cabling plants being used to carry 1000BASE-T networking must
comply with the IEEE 802.3ab standards. In particular, the cabling must pass tests for Attenuation, Near-End
