Installing a Fan Module in an EX4300 Switch
Each fan module is a hot-removable and hot-insertable field-replaceable unit (FRU) installed in the rear
panel of the switch: You can remove and replace it without powering off the switch or disrupting switch
functions.
CAUTION:
Do not mix:
•
Fan modules with different airflow labels (AIR IN (AFI) and AIR OUT (AFO)) in the
same chassis.
•
Power supplies with different airflow labels (AIR IN (AFI) and AIR OUT (AFO)) in the
same chassis.
•
Power supplies and fan modules with different airflow labels (AIR IN (AFI) and AIR
OUT (AFO)) in the same chassis.
•
AC and DC power supplies in the same chassis.
Before you install a fan module in the switch:
•
Ensure you understand how to prevent electrostatic discharge (ESD) damage. See
Electrostatic Discharge Damage” on page 242
.
Ensure that you have the following parts and tools available to install a fan module in the switch chassis:
•
ESD grounding strap
•
Phillips (+) screwdriver, number 2
NOTE:
The fan module slots are at the left end of the rear panel on 24-port and 48-port switches,
and at the right end on 32-port switches.
shows how to install a fan
module in 24- port or 48-port switches. The procedure is the same for 32-port switches.
