WARNING: Leakage Current (High Touch Current) in AC-powered systems with more than 3+1 power
supplies. The power cord plugs must be secured to the building outlets by the qualified chassis installer or a
qualified electrician.
WARNING: The C300 operates in either of two voltage ranges. Each range supports a different power supply
configuration. As a safety precaution, do not install more than the recommended maximum number of PSUs
(given by the table below), as this causes high leakage current. Install blank panels in all unused PSU slots.
NOTE: For system input power requirements see System Specifications on page 62 .
You can install any AC power supply into any power supply slot. Dell Force10 recommends installing
power supplies starting from the left side of the chassis, leaving no blank slots between units.
To install an AC power supply:
