Abstract
A system for providing power to a network interface device (NID) includes a primary power supply device (PPSD), a battery backup device (BBD), and an electrical bus connecting the PPSD, the BBD, and the NID in parallel. The PPSD is operable to power the NID. The BBD is configured to provide power to the NID in response to a power loss event, such as the PPSD failing to provide adequate power to the NID.
