Each power supply has its own fan and is cooled by its own internal cooling system. EX9253 switches
support 800 W and 1600 W AC power supply. The AC power supply supports the low line (90 through
140 VAC) and the high line (180 through 264 VAC) AC power configurations. Each AC power supply has
a single AC appliance inlet located on the power supply that requires a dedicated AC power feed. We
recommend that you use a customer site circuit breaker rated for 15 A @ 100 VAC or 16 A @ 200 VAC
circuit breaker minimum for each AC power supply, or as required by local code. Doing so enables you to
operate the switch in any configuration without upgrading the power infrastructure.
