PWR-CH1-400WAC Cisco C8500L 400W AC Power Supply

PWR-CH1-400WAC is the 400 W AC power supply for the Cisco Catalyst 8500L-8S4X Edge Platform (C8500L-8S4X), the Cisco C8500L 400W AC Power supply. PWR-CH1-400WAC= is the matching spare. The platform is always provided with a second, identical supply, so power continues if one supply fails or one input line is lost, and AC and DC supplies are never mixed in one chassis.

The AC module has a 424 W power rating and a 400 W output. Efficiency is 80 Plus Silver at 85% with 20% load, 89% at 50% load and 85% at 100% load. Input current is under 3 A at 200 Vac and under 6 A at 100 Vac, output holdup time is 20 ms (power-OK holdup 5 ms), and the input receptacle is an IEC 320 style inlet.

Each module has a retention latch, an AC socket, an Alarm Fail LED and a Status LED. The two supplies are hot-swappable, so with redundant supplies in use one can be replaced while the router stays in service. A blank must fill the slot until a new supply is installed. Connect each supply to a separate input power source, on its own circuit, so that one tripped breaker cannot take down the chassis.

The same chassis also takes the PWR-CH1-400WDC DC supply and the PWR-CC1-400WHV high-voltage AC/DC supply, which are the DC and HVAC/HVDC versions for the C8500L-8S4X.
