277V 2200 Watt Power Supply

CS500 277V 2200W power supply module.

CS500 model 3211 compute uses two 2200W power supply modules in a 1+1 redundant power configuration for sites that supply 200-277VAC facility power.

Important: If a CS500 system has two 277VAC power supplies installed and one power supply is not connected to an AC power source while the system is booted, the S2600BP emergency CPU clock may malfunction. To resolve the issue, connect both power supplies to an AC power source.
The 2200W power supplies include a single two-color status LED:
