5. Install the replacement fan.

6. Tighten the captive screws on the faceplate of the fan module by using your fingers. If you are unable

to tighten the captive screws by using your fingers, use the screwdriver.

Figure 46: Removing a Fan Module from an EX4650 Switch

g022522

NOTE:

Both the fan modules must be installed and operational for optimal functioning of the

switch.

Installing a Fan Module in an EX4650 Switch

EX4650 is shipped with redundant fans (4+1). 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.
