we will install multiple units seperate power groups - Protection time: min 30 minutes
this will cover most outages - overall system must be very reliable

- long-lasting battery live
- hot-swapable batteries (add/remove/swap)
- both AC-output (switches/servers) and DC-output (radios)
- type: double conversion
- Managable via Ethernet port on both SNMP and WEB
- monitor/alarm at loss of source-power
- monitor/alarm at battery dead/empty
Nice to haves
