Power
Power is provided on site. A backup generator is also included. However, we include our own backup power using an EdgePower 24V 72W and two 24Ah LiFePO4 batteries. The batteries are mounted on a 2U shelf mounted towards the bottom of the equipment rack and provide ~1 day of backup power. The rack already contains other batteries for separate equipment so this is compromise between space, weight, and runtime.

Commercial Neighbors
Etheric Networks, Inc. shared tenancy at Sunol Ridge. They license (WQUA557 WRJT283) spectrum in the 5.96 GHz (60 MHz), 6.09 GHz (30 MHz), 6.21 GHz (60 MHz) and 10.8 GHz range. Unlike many microwave tenants, the licensed band overlaps with the WiFi 6E spectrum which must defer to their use. Care must be taken when running a backbone link through this site, although we are unlikely to be run links in similar directions.
Other Neighbors
The site also contains many other radios, including radios for Alameda County, the emergency services and Alameda County OES. The primary EOC is located in Dublin. (map)
