• In North American, use a 20-amp-minimum circuit with one NEMA AB1
class 14B breaker for each 16-amp Power Distribution Unit (PDU).
• In Europe:
◊ For a single NetServer in a rack, use a 15-amp-minimum circuit with
one IEC MCB C-type breaker for each 16-amp PDU.
◊ For multiple NetServers in a rack, use a 15-amp-minimum circuit with
one IEC MCB D-type breaker for each 16-amp power distribution
unit.
Each 16-amp PDU can accommodate a maximum of two NetServers.
When the proper power supply is available, connect the NetServer to the AC
power source.

source. If the NetServer passes the tests, you will see:
