The internal electrical busways provide a location to connect each of the drop boxes, which then power
the PDUs. Stagger the drop boxes on the electrical busways; one connected to the A-side busway and the
next connected to the B-side busway.
Disabling power
• To disable power to a single PDU, open the drop box breaker feeding that PDU and disconnect the
PDU from the drop box.
• To disable power to a single rack, open the corresponding breakers on the drop boxes feeding each
of the PDUs installed in that rack.
• To disable power to a single electrical busway, open the appropriate main breaker for that busway
on the corresponding electrical busway panel outside of the HP POD.
