We received a bunch of network alarms this morning around ~5:00am.

Upon investigation I discovered that one of the redundant links (port channel) between our core routers and the dev distribution switch (devmc02sw1) went into error disable mode and shut down.

This was caused by a bad/failing fiber optic transceiver module in the switch. This caused a brief network interruption while the traffic re-converged.

With EXTECH Electromagnetic Field EMF ADAPTER Model 480824, did a search for 60 Hz noise from the gun to the PSS Gate. The adapter was attached to a Voltmeter. It has a sensitivity of 1mGauss - 1mVdc and a range of 0.1mGuass to 199.9mGauss with 30 to 300Hz operational bandwidth.

In the KeV Region: all showed 0.1 mV or less except for the Buncher that showed 0.5 mV (see Photo 1). The PreBuncher showed the background value (0.1 mV) - see Photo 2. The PreBuncher and Buncher have no active heating. The PreBuncher has a heat jacket and the Buncher is bare.
