The network switch in the CER had problems this morning. It spontaneously rebooted several times. I am fairly confident it is a power supply problem which we would generally not notice if the second supply was installed but in this case it was not. I have installed the second supply and will finish installing the 48V DC Feed to the switch as the backup supply to fix this situation.
This posed a problem for Peter K in the PSL as he could not see his normal video screens while the system rebooted.
