Removing a Fan Tray from 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.
CAUTION: Do not remove the fan tray unless you have a replacement fan
tray available.
Before you remove 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
•
Replacement fan tray
To remove a fan tray from an EX9200 switch chassis:
1. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD
point on the chassis.
2. Loosen the captive screws on the fan tray faceplate using a screwdriver.
3. Grasp the fan tray handle, and pull it out approximately 1 to 3 inches.
4. Press the latch located on the inside of the fan tray to release it from the chassis.
5. Place one hand under the fan tray to support it, and pull the fan tray completely out
of the chassis.
Figure 63 on page 213 shows removing a fan try from an EX9208 switch. The procedure
and orientation of the fan tray are the same for EX9204. The procedure is the same for
EX9214 switch; however, the orientation of the fan try is different— it is installed
horizontally into the top and bottom of the chassis (see Figure 64 on page 214).
