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

The fan modules and the power supplies in EX3400 switches are hot-removable and
hot-insertable field-replaceable units (FRU): You can remove and replace them without
powering off the switch or disrupting switch functions.
CAUTION:
Do not mix power supplies and fan modules with different airflow labels (AIR IN
(AFI) and AIR OUT (AFO)) in the same chassis.
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 EX3400 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.
Two persons are required for this procedure.
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:
We recommend that you connect
DC or
AC-powered systems to earth ground.
The power cord inlet and earthing terminal are on the rear panel of the switch.
1. Secure the grounding lug over the earthing terminal on the rear panel by using
washers and screws.
2. Push the end of the retainer strip into the slot above the power cord inlet until the strip
snaps into place. Ensure that the loop in the retainer strip faces toward the power
cord.
