Cisco ME34X-PWR-AC= Power Supply Unit Battery And Power Supply

For ME-3400E-24TS-M and ME-3400EG-12CS-M

The 80-W AC-power-supply module is an autoranging unit that supports input voltages between 85 and 264 VAC. The DC-power-supply module has dual input feeds (A and B) and supports input voltages between -36 to -72 VDC for telecom applications and +18 to +36 VDC for industrial applications.

The AC-power-supply modules ship with a power cord to connect to an AC-power outlet. The DC-power-supply module ships with a terminal block to be wired for DC-power outlet connections.

Each power supply is cooled by internal fans. For maximum efficiency, at least two of the four fans should be operational in a warm environment. A fan failure triggers an alarm. When a fan fails, replace the power supply immediately.
