Register product serial numbers on the Juniper Networks website and update the
installation base data if there is any addition or change to the installation base or if the
installation base is moved. Juniper Networks will not be held accountable for not meeting
the hardware replacement service-level agreement for products that do not have
registered serial numbers or accurate installation base data.

WARNING: Ensure that you understand how to prevent electrostatic discharge
(ESD) damage. Attach the ESD grounding strap to your bare wrist, and connect the
strap to the ESD point on the chassis.
Part 1: Mount the Switch on Two Posts of a Rack
You can mount an EX2300 switch on a desk or a level surface, on two or four posts of a
rack or cabinet, or on a wall. This guide describes the procedure to mount the switch on
two posts of a rack.
Mounting an EX2300 switch on a rack requires one person to lift the switch and a second
person to install the mounting screws.
1. Place the rack in its permanent location, allowing adequate clearance for airflow and
maintenance, and secure it to the building structure.
NOTE: When you mount multiple units on a rack, mount the heaviest unit at the bottom
and mount the other units from bottom to top in decreasing order of weight.
2. Align the mounting brackets along the front of the side panels of the chassis.
3. Attach the brackets to the chassis by using the mounting screws. Tighten the screws.
4. 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 rail.
Align the bottom hole in each mounting bracket with a hole in each rail, making sure
that the chassis is level.
5. Have the second person secure the switch to the rack by using the appropriate
screws. Tighten the screws.
Part 2: Connect Power to the Switch
NOTE: Grounding is required for DC systems and recommended for AC systems. An
AC-powered switch gets additional grounding when you plug the power supply in the
switch into a grounded AC power outlet by using the power cord.
To connect earth ground to a switch:
CAUTION: A licensed electrician must attach the lug to the grounding cable.
1. Secure the grounding lug on the grounding cable to the earthing terminal on the rear
panel of the switch by using washers and screws.
2. Connect the other end of the grounding cable to a proper earth ground.
To connect power to an AC-powered switch:
The power cord inlet is on the rear panel of the switch.
1. Squeeze the sides of the power cord retainer clip and insert the L-shaped ends of the
wire clip into the holes in the brackets above and below the power cord inlet.
2. Insert the coupler end of the power cord into the AC power cord inlet.
3. Push the cord into the slot in the adjustment nut of the power cord retainer. Turn the
nut until it is snug against the base of the coupler and the slot in the nut is turned 90°
from the top of the switch.
4. If the power outlet has a power switch, set it to the off (0) position.
5. Insert power cord plug into the power source outlet.
6. If the power source outlet has a power switch, set it to the on (|) position.
To connect power to a DC-powered switch:
The DC power inlet is on the rear panel of the switch. It has four terminals labeled
INPUT1+, INPUT1–, INPUT2+, and INPUT2–. The DC power inlet has a clear plastic
cover.
WARNING: Ensure that the input circuit breaker is open so that the cable leads do
not become active while you are connecting DC power.
1. Grasp the cover in the middle, gently bend it outward, and pull it out. Save the cover.
2. Remove the screws on the terminals. Save the screws.
