Planning and Installation
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.
