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.

The fan modules and the power supply modules in the EX4300 switches are hot-removable and hot-insertable field-replaceable
units (FRUs) installed in the rear panel of the switch. You can remove and replace them without powering off the switch or
disrupting switch functions.
CAUTION:
Do not mix:
•
AC and DC power supplies in the same chassis.
•
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 ESD damage. Wrap and fasten one end of an ESD wrist strap
around your bare wrist, and connect the other end of the strap to the ESD point on the switch.
NOTE: Power supplies and fan modules must have the same airflow direction (all AFI or all AFO). The AIR IN (AFI)
and AIR OUT (AFO) labels on the power supplies must match the AIR IN (AFI) and AIR OUT (AFO) labels, respectively,
on the fan modules..
