[RTM-BLO-V1] Isolation guards around input connectors
After a quick chat with Nico Voumard, he gave us some insight about better connection in the rear panel.
For better isolation, isolation guards should be placed around the LEMO input connectors in the back panel.
Apart from that we talked about grounds and isolation (grounds for the racks, transceiver and receivers) that must be consider in a future review for V2.
