Mounting an EX Series Redundant Power System on Four Posts in a Rack or Cabinet
You can mount a Redundant Power System (RPS) on four posts of a 19-in. rack or cabinet by using the separately orderable four-post rack-mount kit. (The remainder of this topic uses “rack” to mean “rack or cabinet.”)
You can position either the switch connector side or the power supply side of the RPS at the front of the rack.
Before mounting the RPS on four posts in a rack:
Verify that the site meets the requirements described in Site Preparation Checklist for an EX Series Redundant Power System.
Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure it to the building structure (see Clearance Requirements for Airflow and Hardware Maintenance for an EX Series Redundant Power System).
Remove the RPS from the shipping carton (see Unpacking an EX Series Redundant Power System).
Ensure that you have the following parts and tools available:
Phillips (+) screwdriver, number 2
6 flat-head 4-40 mounting screws (provided with the four-post rack-mount kit)
12 flat-head 4x6-mm Phillips mounting screws (provided with the four-post rack-mount kit)
One pair each of flush or 2-inch-recess front brackets
One pair of side-rail brackets
One pair of rear brackets
Screws to secure the chassis and the rear brackets to the rack (not provided)
We recommend that you first mount the RPS and then install the power supplies in it.
If you are mounting multiple RPSs on a rack, mount the heaviest RPS at the bottom of the rack and mount the other RPSs from the bottom of the rack to the top in decreasing order of the weight of the units.
To mount the RPS on four posts in a rack:
- Attach the front brackets (either the flush or the 2-inch-recess brackets) to the side-rail brackets using the six 4-40 flat-head Phillips mounting screws. See Figure 1.
- Place the RPS on a flat, stable surface.
- Align the side-rail brackets along the side panels of the chassis.
- Insert the 4x6-mm Phillips flat-head mounting screws into the aligned holes and tighten the screws. See Figure 2.
- Have one person grasp both sides of the RPS, lift the RPS and position it in the rack, aligning the side-rail bracket holes with the threaded holes in the front post of the rack. Align the bottom hole in both the mounting brackets with a hole in each rack rail, making sure the chassis is level. See Figure 3.
- Have a second person secure the front of the RPS to the rack by using the appropriate screws for your rack.
- Slide the rear brackets into the side-rail brackets. See Figure 4.
- Attach the rear brackets to the rear post by using the appropriate screws for your rack. Tighten the screws.
- Ensure that the chassis is level by verifying that all the screws on the front of the rack are aligned with the screws at the back of the rack.
