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 191
.
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 (not provided)
NOTE:
The fan module slots are located between the Management ports and PSUs.
NOTE:
If you have a Juniper J-Care service contract, register any addition, change, or upgrade of
hardware components at
https://www.juniper.net/customers/support/tools/updateinstallbase/
.
Failure to do so can result in significant delays if you need replacement parts. This note does not
apply if you replace existing components with the same type of component.
1. Ensure that you have the correct fan module. The label AIR IN (AFI) or AIR OUT (AFO) on the fan
module must match the label AIR IN (AFI) or AIR OUT (AFO) on the installed power supply.
2. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the
chassis.
3. Remove the fan module from its bag.
4. Hold the handle of the fan module with one hand and support the weight of the module with the other
hand. Place the fan module in the fan module slot on the rear panel of the switch and slide it in until it
is fully seated and latched.
5. Tighten the captive screws on the faceplate of the fan module by using the screwdriver. The
recommended torque value is 4.34 in-lb (0.49 Nm). See
