Like 1000BASE-T, 10GBASE-T requires testing of all the crosstalk and return loss parameters described
preceding "Note on 1000BASE-T cable requirements", and also ANEXT.
In addition to ANEXT, 10GBASE-T is more sensitive to external electrical noise in the environment. Hewlett
Packard Enterprise recommends keeping radio transmitters and other sources of high frequency continuous wave
radio frequency away from LAN cables.
NOTE: HPE Smart Rate speeds for the JL323A 2930M switch and the JL081A Aruba 3810M/2930M
4 Smart rate PoE+ Module are 1, 2.5, 5, 10GbE.
When testing your cabling, be sure to include the patch cables that connect the switch and other end devices to
the patch panels on your site. The patch cables are frequently overlooked when testing cable and they must also
comply with the cabling standards. For 10GBASE-T, Category 6 patch cables are sensitive to movement once link
has been established, and could cause link to drop if moved. Therefore, Hewlett Packard Enterprise recommends
using Category 6A patch cables. As an alternative, use cable management options to tie down (dress) the
Category 6 patch cables so they cannot move.
For Conducted and Radiated Immunity in accordance with EN55024, the Aruba 2930M switches are limited to
Performance Criteria A with shielded cables (CAT6/6A).
