Notes:
- The power supplies for AC or DC voltage do not change. Only the power chunnel is different. The
power chunnel uses internal cables to carry power from the rear of the system node to the power
supplies that are in the front of the system node.
- All measurements made in conformance with ISO 7779 and declared in conformance with ISO
9296.
- AC and HVDC power supplies cannot be mixed in the same server or I/O drawer. IBM® recommends that AC products and HVDC products with HVDC PDUs are installed
in separate racks. However, AC and HVDC products can be supported in the same rack if all grounding
(earthing) is done in accordance with the applicable electrical code or codes. IBM provides documentation for different AC and HVDC products about the
disconnecting means for service. If a different disconnecting means is to be used for service of the
equipment in a rack with AC-powered and DC-powered products, the disconnecting means must be made
clear to service.
