a. Align the two parts of the adjustable mounting rail as shown in the following illustration.
b. Secure the two adjustable mounting rail parts with three screws that come with the rack-mounting
kit.
3. Align the adjustable mounting rails with the holes in the side rear of the PDU and attach the mounting
rails to the PDU with three M3 pan-head screws with captive lock washers per rail. Use the screws that
come with the rack-mounting kit.
4. Orient the PDU so that the vent holes are facing up. Hold the PDU at a slight angle and carefully insert it
into the 1U mounting space in the rack cabinet. Pushing in slightly on both of the adjustable mounting
rails helps clear the rails from the rack flanges.
5. Secure the end of the PDU that has the short mounting brackets to the rack cabinet first. Make sure that
the short mounting brackets are aligned with the outside of the rack flanges. Attach the brackets to the
rack flanges with two M6 screws and two cage nuts or clip nuts per bracket. Use the cage nuts or clip
nuts and the screws that come with the rack-mounting kit.
