To provide two-way communication, connect a management link cable from the power management module of the 1U power enclosure to the server blade enclosure (Figure 5).

Power distribution unit cables

If PDUs are being used, they must be connected to the 1U power enclosure in three steps. First, before connecting any PDU power cables, turn off or disconnect facility AC power from the PDUs. Secondly, connect the PDU power cables to the AC power input connectors on the 1U power enclosure (see Figure 6). Lastly, once the PDU power cables are connected to the PDUs, power to the PDUs can be restored.
