Mounting an EX4300 Switch on Two Posts of a Rack or Cabinet
You can mount an EX4300 switch on two posts of a 19-in. rack (either a two-post or a four-post rack) or a 19-in. cabinet by using the mounting brackets provided with the switch. (The remainder of this topic uses rack to mean rack or cabinet.)
You can mount the switch on four posts of a four-post rack by using the mounting brackets provided with the separately orderable four-post rack-mount kit. See Mounting an EX4300 Switch on Four Posts of a Rack or Cabinet.
If you need to mount the switch in a recessed position on two posts of 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.
Before mounting the switch on two 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)
2 mounting brackets and 8 mounting screws (provided in the accessory box shipped with the switch)
Screws to secure the chassis to the rack (not provided)
2-in.-recess front-mounting brackets if you will mount the switch in a recessed position (part of the separately orderable four-post rack-mount kit)
Cover panels for uplink module and power supply slots (provided)
One person must be available to lift the switch while another secures the switch to the rack.
If you are mounting multiple switches on a rack, mount a switch in the bottom of the rack first and proceed to mount the rest of the switches from bottom to top.
To mount the switch on two posts of a rack:
- Place the switch on a flat, stable surface.
- Align the mounting brackets along the front, rear, or center of the side panels of the switch chassis depending on how you want to mount the switch. For example, if you want to front-mount EX4300 switches except EX4300-48MP and EX4300-48MP-S switches, align the brackets along the front of the side panel (see Figure 1). If you want to front-mount an EX4300-48MP or EX4300-48MP-S switch, align the brackets 17.5 mm offset from the front panel (see Figure 2 and Figure 3).
- Align the bottom holes in the mounting brackets with the holes on the side panels of the switch chassis.
- Insert mounting screws into the aligned holes. Tighten the screws by using the Phillips (+) screwdriver.
- Ensure that the other holes in the mounting brackets are aligned with the holes in the side panels. Insert a screw in each hole and tighten the screws by using the Phillips (+) screwdriver.
- Have one person grasp both sides of the switch, lift the switch, and position it in the rack, aligning the mounting bracket holes with the threaded holes in the rack or cabinet rail. Align the bottom hole in both the mounting brackets with a hole in each rack rail, making sure the chassis is level. See Figure 4.
- Have a second person secure the switch to the rack by using the appropriate screws. Tighten the screws.
- Ensure that the switch chassis is level by verifying that all screws on one side of the rack are aligned with the screws on the other side.
We recommend that you install cover panels in the unused uplink module and power supply slots.
