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

Twisted-pair copper 1000 Mbps Operation Category 5, 100-ohm 4-pair UTP or STP cable, complying
with IEEE 802.3ab 1000BASE-T specifications—Category 5e
or better is recommended. See
“Note on 1000BASE-T
cable requirements” .
10 Gbps Operation Category 6 or 6A, 100-ohm 4-pair UTP cable, or Category 6A
or 7, 100-ohm 4-pair STP cable, complying with IEEE
802.3an 10GBASE-T specifications.
See Note on 10GBASE-T cable requirements below, and
see “Technology distance specifications” for distances
supported with each cable type.
CAT6A F/FTP, S/FTP, SF/FTP highly recommended in noisy
environments. Refer to
