Figure 2-13: Incorrect Cabling in the Primary Rack
INCORRECT
Power Cabling to the Control Frame
within the Primary Rack
Do NOT connect both power supplies of a Control Frame cluster (i.e. CL1) to
the same PDU. Doing this will eliminate the power redundancy configuration
and will result in the Control Frame losing all power if one PDU fails.
