Power distribution units
Power planning for an Flex System Enterprise Chassis is essential.
The Enterprise Chassis has a maximum of six power supplies installed. So, careful consideration must be
given to providing the best power-optimized source. Both N+N and N+1 configurations are supported for
maximum flexibility in power redundancy. Each AC power supply in the chassis has a 16A C20 three-pin
socket and can be fed by a C19 power cable, from a suitable supply.
The chassis has the ability to accommodate a maximum of six power supplies, so it is possible to balance
a three-phase power input into a single chassis or a group of chassis. The chassis power system is
designed for efficiency using data center power consisting of three-phase, 60A Delta 200 VAC (North
America) or three-phase 32A wye 380-415 VAC (international). The chassis can also be fed from single-
phase 200 - 240VAC supplies, if required.
