AC Power Supply Units
The 2500W AC Power Supply Unit is capable of operating at either 100 VAC or 220 VAC. If the system
is connected to a 100 VAC power supply, each unit provides up to 1500W, and three power supply
modules are required to power the system; four power supply units are required for power supply
redundancy.
If the system is connected to a 220 VAC power supply, two power supply units are required for providing
power to the system, three power supply units are required for power supply redundancy, and four power
supply units are required for full facility redundancy.
Full facility redundancy requires two independent power sources (feeds) with two power supplies on
each feed. Each independent power source should have a dedicated circuit breaker sized in accordance
with your local electrical codes.
CAUTION: Before removing and replacing a power supply unit, determine if the E600i is in full redundancy or
non-redundant mode. Operating in non-redundant mode will require a complete system power off when
removing and replacing a power supply.
NOTE: Do not mix power supplies. Installing a 2500W-AC2 power supply into a chassis with 2500W-AC
power supplies already installed may result in unpredictable behavior. FTOS version 8.3.1.2 and later will
declare an alarm when the PSUs are mixed.
