Power Supply
The MX7000 Power Supplies will utilize a new front-loading form factor developed for the MX portfolio. Up to six PSUs plug into the
front of the chassis. These mate directly with connectors on the Main DB. The AC connections come from the rear of the chassis
cabling to connections on the PDB. The Platinum PSUs support 3000W output with high line AC input. For low line input the PSUs
will output approximately 1400W. Low line will not be supported at RTS. If low line is ever supported, mixed high line and low line AC
inputs in the same chassis will not be supported. The supplies are set nominally to output 12.2V DC at the output.
