• Only AC power drawers are supported in the rack or cabinet. It is strongly recommended to use a
power distribution unit that meets the same specications as IBM power distribution units to supply
rack power (for example, FC 7188). Rack or cabinet power distribution devices must meet the drawer
voltage, amperage, and power requirements, as well as that of any additional products that are
connected to the same power distribution device.
The rack or cabinet power receptacle (power distribution unit, uninterruptible power supply, or multi-
outlet strip) must have a compatible plug type for your drawer or device.
