Running Cable Diagnostics
With high-speed data networking, the suitability of the cable in achieving maximum transfer rates is
especially important. SAM’s cable diagnostic tool can be used to verify the attached cable, reporting
its condition, measured length and electrical characteristics for each cable pairing.

. Offline testing produce more detailed results, but at
the expense of disrupting the connection while tests are running.
NOTE:
Cable diagnostics are only available on Solarflare 10GBASE-T Adapters. For these
adapters, Solarflare recommend using good quality Category 6, 6a or 7 cable up to the
maximum length as determined by the cable category.
CAUTION:
The offline tests will cause the network link to momentarily drop and disrupt data flow.
Solarflare recommend only running diagnostics tests when disruption to your services can be
tolerated.
