[Lerftest-ctrls] Issue with LLRF-CPU networking

[Wesley Moore]

Sonya,


Larry is seeing a comm issue from lcls-llrfcpu01 to the rack's switch.  Port 1 on the cpu appears inactive/dead (pic 1).  This results in the uplink in the rack being down (pic 2).  Larry moved from Port 1 to another port up and saw the uplink briefly.  So it's believed that everything downstream of cpu01 is fine.  Please advise.


# pic 1: lcls-llrfcpu01, port 1 inactive.

# pic 2: LLRF rack switch, all lights on left are solid, uplink on far-right is inactive.
