Power Supply For Hardened Network Switch
The Owner is supplying a Fortinet 112D-POE hardened network switch which the Owner will install in an integrator-supplied NEMA4x cabinet next to a large industrial gate operator. The cabinet also contains Mercury controllers and other devices, all of which are powered by a Life Safety power supply (also located in the cabinet). What would you recommend to power this switch with a battery standby of 4-8 hours? Specs require a 48VDC power supply.
