You also need to supply:
Antistatic wrist strap
Clean work table, or area, near the rack
Caution - Because of the their size and weight, you will need another person to help lift and install the PDU into the rack (see Standard PDU Physical Specifications to review the size and weights of each PDU). You might also need additional help when routing the PDU power input cables.
You can install up to two PDUs, one per side, into the Sun Rack II cabinet. You can install these PDUs anywhere between the rear RETMA rail and the rack’s rear frame. Provide adequate space to route the power input lead cords and any equipment data cables.
Each mounting bracket contains two additional screw holes used to secure a PDU to the bracket when a PDU ships in a rack from the factory (see Removing Shipping Screws From PDU for more information). Ignore these shipping screw holes when installing the PDU into the rack.
Figure 2-1 Installing a PDU Into a Sun Rack II Cabinet
The PDU is held in the rack by gravity, with the standoff bolts resting in the mounting brackets’ keyhole slots.
Note - The circuit breakers must face the rear of the rack so that you can reset a breaker if one trips.
For extra durability, secure the PDU to the mounting brackets using the shipping screws and washers (two screws and washers per bracket). If you plan to ship the rack to another location, you must secure the PDU using these shipping screws.

Route the power input lead cords either down through the bottom of the rack (see Routing Power Input Lead Cords Down Through the Bottom of the Rack), or up through the top of the rack (see Routing the Power Input Lead Cords Through the Top Cable Window), depending on where you plan to connect them to the main power source.
If you are routing the cables through the bottom of the rack, refer to the Sun Rack II User’s Guide for the dimensions of the floor cutout.
Caution - Never twist, kink, or tightly bend a power input lead.

Figure 2-6 Routing the Power Input Lead Cords Through the Top Cable Window
Caution - If you route power input lead cords through the top cable window, do not rest the cables on the plastic sliding doors.
Install these brackets near where the power input leads exit the rack (see Routing Power Input Lead Cords Down Through the Bottom of the Rack and Routing the Power Input Lead Cords Through the Top Cable Window).
