Installing a Fan Tray in an EX9200 Switch
The fan tray in an EX9200 switch is a hot-insertable and hot-removable field-replaceable
unit (FRU); You can remove and replace it while the switch is running without turning off
power to the switch or disrupting switching functions.
Before you begin to install a fan tray:
•
Ensure you understand how to prevent electrostatic discharge (ESD) damage. See
“Prevention of Electrostatic Discharge Damage” on page 351.
Ensure that you have the following parts and tools available:
•
ESD grounding strap
•
Phillips (+) screwdrivers, number 1 and 2
CAUTION: The fan tray can be removed and replaced while the switch is
operating. However, the fan tray must be replaced within 2 minutes of
removing the fan tray to prevent the chassis from overheating.
To install a fan tray in an EX9200 switch:
1. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD
point on the chassis.
2. Grasp the fan tray handle, and insert it straight into the chassis. Note the correct
orientation by the This side up label on the top surface of the fan tray.
3. Tighten the captive screws using a screwdriver on the fan tray faceplate to secure it
in the chassis.
Figure 61 on page 210 shows installing a fan try in an EX9208 switch. The procedure and
orientation of the fan tray are the same forEX9204.The procedure is the same for EX9214
