Figure 70 DMX-3 power cabling requirement
Note: Symmetrix DMX-3 requires two dedicated and isolated AC power
feeds that plug directly into the PDPs of the bays. The customer must supply
separate PDU connections for proper power redundancy. DMX-3 power
redundancy can only be assured at the customer PDU and after. These labels
are only to be removed from the cables by the customer’s site electrician.

Two separate dedicated
and isolated customer site
PDUs are required. For site
preparation and power
connection procedures,
refer to the EMC Symmetrix
DMX-3 and DMX-4 Best
Practices Guide for AC
Power Connections.
This illustration shows two
types of labels that are
equivalent in the information
they present. Either of these
labels are attached to the
PDP power cords.
The same label can be
found inside the rear door of
the system bay and storage
bays.
