Cannot ping the EPC
Network cable is connected but shows as disconnected in Network settings
No green light on Ethernet cable port
MS removed from DHCP, but information does not populate on electronics reboot

CAUSE

ACQUITY Sample Manager power is off (the network hub resides in this unit). If the ACQUITY module is turned off, there is no power supply to the network box and therefore no Ethernet connections.

FIX or WORKAROUND

Close MassLynx.
Turn on the ACQUITY Sample Manager and wait for the Run LED to stop blinking.
Restart MS electronics (with pump override in override position if appropriate).
Open MassLynx.
Ensure that communications are established.
