Preparing to Install an RP-Series PDU
Before you install a PDU, plan how to route the power cable. It can be routed through the bottom of the Cisco
R42612 rack, through the two knockout cabling portholes on the top enclosure of the rack, or through the
large opening with brushes at the rear of the top enclosure of the rack.
Installing a Zero-U PDU
There are five models of PDUs that can be mounted vertically in a Cisco R42612 Rack. These PDUs can be
installed on the PDU trays on both sides of the rack; the PDUs do no require any RU space, so they are also
referred to a zero-U PDUs.
The Cisco R42612 rack can accommodate up to six zero-U PDUs. When servicing Cisco UCS servers, some
products may require the temporary removal of cables to provide service space for rear-facing field replaceable
units (FRUs).
Note
For additional information on how to install a PDU, see the Eaton ePDU G3 Installation and Connectivity
Quick Start or the Eaton Enclosure Power Distribution Unit (ePDU) G3 - Operations Manual.
The following table provides descriptions for these PDUs. For detailed specifications and illustrations, see
PDU Specifications.

The RP208-60M3P-12-9 PDU must be installed in the rear facing locations as shown in Figure 5: One Zero-U
PDU Installed on the Rear-Facing Flange, on page 6. The increased size of this PDU requires the rear-facing
installation to avoid interference with equipment and cabling.
Note
No serviceable parts inside. To avoid risk of electric shock, do not open.
Warning
Read the installation instructions before using, installing or connecting the system to the power source.
Warning
This product relies on the building’s installation for short-circuit (overcurrent) protection. To reduce risk of
electric shock or fire, ensure that the protective device is rated not greater than:
Warning
This equipment must be grounded. To reduce the risk of electric shock, never defeat the ground conductor or
operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical
inspection authority or an electrician if you are uncertain that suitable grounding is available.

Installing a Zero-U PDU

For Nordic countries (Norway, Finland, Sweden and Denmark) this system must be installed in a Restricted
Access Location, where the voltage of the main ground connection of all equipment is the same (equipotential
earth) and the system is connected to a grounded electrical outlet.
Warning
Connect the device to a grounded power outlet.
Warning
You can install up to six zero-U PDUs in the Cisco R42612 Rack. When servicing UCS servers, some products
may require temporary removal of cables to provide service space for rear-facing field replaceable units
(FRUs). Due to height restrictions, RP208-60M3P-12-9 must be installed facing the rear of the rack.
Each PDU needs a PDU retention bracket attached to the top of the PDU. When secured to the PDU tray, the
PDU retention bracket ensures that each PDU is securely held in place.
With the rear of the rack open, follow these steps to install a zero-U PDU:
Procedure
Step 1 Insert the mounting button on the back of the PDU into a key hole near the top of the PDU tray or into the
top key hole of the rear-facing flange. Callout 1 in the following figure shows the mounting button and the
key hole of the PDU tray on the side of the rack.

Step 2 Slide the PDU down slightly so that it locks into place in the key hole on the PDU tray (see callout 2 in the
preceding figure) or the rear-facing flange.
Step 3 Secure the lower PDU mounting button into place as in steps 1 and 2.
Step 4 Install a PDU retention bracket on the top of the PDU as shown in the following figure. Secure the bracket
to the PDU tray with the screws provided.

Step 5 Route the PDU power cable either through the large access opening in the back of the rack canopy.
Step 6 Connect the PDU power cord to the AC power source.
The following figure shows a single zero-U PDU installed in the PDU tray.
