Step 3. Internal wiring

The XPS gets its power from the power distribution module or PDM (4100U and 4100ES only) or the power distribution terminal block (4100-2301
expansion bay only). The PDM or terminal block takes power directly from the AC mains and the two backup batteries, and distributes power to each
bay in the cabinet.
Figure 5 shows the PDM in the 4100U/4100ES connecting to a host FACU with two XPSs.
