Mounting an EX4300 Switch on Four Posts of a Rack or Cabinet
You can mount an EX4300 switch on four posts of a 19-in. rack or a 19-in. 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 mount the switch on two posts of either a two-post rack or a four-post rack by using the mounting brackets provided with the switch. See Mounting an EX4300 Switch on Two Posts of a Rack or Cabinet.
If you need to mount the switch in a recessed position on either a two-post rack or a four-post rack, you can use the 2-in.-recess front-mounting brackets provided in the separately orderable four-post rack-mount kit.
To ensure that the protective earthing terminal is accessible through the opening in the rear mounting-blade:
Ensure that the rack is 27.5 in. (70 cm) through 30.5 in. (77.5 cm) deep if you are mounting the switch flush with the rack front on four posts of a rack.
Ensure that the rack is 29.5 in. (75 cm) through 32.5 in. (82.5 cm) deep if you will mount the switch 2 in. recessed from the rack front.
Before mounting the switch on four posts of a rack:
Verify that the site meets the requirements described in Site Preparation Checklist for EX4300 Switches.
Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure it to the building structure.
Remove the switch from the shipping carton (see Unpacking an EX4300 Switch).
Ensure that you have the following parts and tools available:
Phillips (+) screwdriver, number 2 (not provided)
6 flat-head 4-40 Phillips 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-in.-recess front-mounting brackets (provided with the four-post rack-mount kit)
One pair of side mounting-rails (provided with the four-post rack-mount kit)
One pair of rear mounting-blades (provided with the four-post rack-mount kit)
Screws to secure the chassis and the rear mounting-blades to the rack (not provided)
Cover panels for uplink module and power supply slots (provided)
One person must be available to lift the switch while another secures it to the rack.
If you are mounting multiple units on a rack, mount the heaviest unit at the bottom of the rack and mount the other units from the bottom of the rack to the top in decreasing order of the weight of the units.
To mount the switch on four posts of a rack:
- Place the switch on a flat, stable surface.
The four-post rack-mount kit ships with the short front-mounting brackets attached to the side mounting-rails. If you want to recess the switch in the rack, you must unscrew the short front-mounting brackets from the side mounting-rails by using the Phillips (+) screwdriver and attach the long front-mounting brackets to the side mounting-rails.
- Align the side mounting-rails along the side panels of the switch chassis. Align the two holes in the rear of the side mounting-rails with the two holes on the rear of the side panels.
- Insert 4x6-mm Phillips flat-head mounting screws into the two aligned holes and tighten the screws by using the screwdriver. Ensure that the remaining four holes in the side mounting-rails are aligned with the four holes in the side panel. See Figure 1.
- Insert the 4x6-mm Phillips flat-head mounting screws into the remaining four holes in the side mounting-rails and tighten the screws by using the screwdriver.
- Have one person grasp both sides of the switch, lift the switch, and position it in the rack, aligning the side mounting-rail holes with the threaded holes in the front post of the rack. Align the bottom hole in both the front-mounting brackets with a hole in each rack rail, making sure the chassis is level. See Figure 2.
- Have a second person secure the front of the switch to the rack by using the appropriate screws for your rack.
- Slide the rear mounting-blades into the side mounting-rails. See Figure 3.
- Attach the rear mounting-blades to the rear post by using the appropriate screws for your rack. Tighten the screws.
- Ensure that the switch 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.
We recommend that you install cover panels in the unused uplink module and power supply slots.
