Investigate adding a 1GB Ethernet Connection to LFAA SPS Network

"The CDR panel suggested that in the event of power loss, under UPS power, some network functionality should remain available. This should at least be able to signal the presence (or lack of) power in each cabinet.

The Cabinet Management Board (CMB) in each cabinet provides limited (~10 minutes) battery power. If a 1Gb network is added to the system, this functionality would be granted. This has the extra advantage of providing LMC functionality with just the CMB powered, limiting the "low power mode" power to <50W per cabinet.

There are a few problems with this solution

• the network must be added to the LFAA PBS. This includes a few (4?) 1Gb switches, and cables. Nothing expensive, but it has to be accounted for in all documents.
• the system works quite well for CPF cabinets. I have no idea of whether a 1Gb LMC connection is available in the RPFs, or whether the connectivity allows this. If not, we have to route everything on the 100 Gb network, i.e. what is done now, and thus a set of equipments must be kept on in low power mode in the MCCS. Could you please point me to what is required, apart from the switches?

Review the proposed solution in the TIMS ticket (TIMN-176) and see if it is viable. Alternatively provide a new proposed solution, such as using existing/expanding NSDN connectivity.
