Cisco R42610 Rack

Mounting PDUs
The PDUs mount in the rear of the rack in two different ways. The first way, shown in 
, is in the 
PDU tray with the receptacles facing sideways into the rack.

  Mounting Cisco Zero-RU PDUs
Although there are mounting holes that support up to 6 PDUs, three on each side in the rear of the Cisco 
R4210 rack, the number of PDUs that can physically be installed will be defined by the depth of the 
equipment that is installed in the rack. For example, if a customer wishes to use a Type 2 PDU to power 
both the UCS chassis and other equipment such as storage in the rack then you will be unable to mount 6 
PDUs in the rack because the chassis will prevent the PDU mounting position closest to the front of the rack 
from being used.
