It is indeed! See above.

1000Mbps Full Duplex

Disconnecting/reconnecting the cable appears to have no effect. Perhaps
I should try plugging into a different port on the switch. Certainly,
another port on the switch remains connected at Gbit rate.
However, the problem appears to have vanished as suddenly as it arrived.
Having had the problem more or less every other day, it hasn't happened
for over a week now! The first time it occured was after the machine
had been powered up for over eight hours. Subsequent occurences were
always apparent immediately from power up.

Okay - fault not currently in evidence, but the 5V reading is 5.08V.
What is the typical/lowest reading you would expect to see on new
device?
