There has been no noticeable loss of communication to the ALGA 50watt amplifier.  As a test, the ethernet cable was removed for about a minute and then reconnected.  The amplifer re-established communication without issue.  This test was done twice.

Now, the CPI ethernet cable has been returned to the CPI amplifier.  The original ALGA ethernet cable (blue) has been reconnected to the ALGA.

PS  The nitrogen bottle has been replaced.
