The fan tray is hot-swappable and can be replaced while the device is powered on.
If the device remains operational during fan tray replacement the procedure must
be completed within 30 seconds.
Use the following procedure to install a fan tray in the switch.
1. Remove the previously installed fan tray from the slot by removing the two
screws with a crosshead or Philips #2 screwdriver.
2. Before opening the package that contains the new fan tray, touch the bag to the
switch casing to discharge any potential static electricity. Using an ESD wrist
strap during installation is recommended.
3. Remove the fan tray from the antistatic shielded bag.
4. Holding the fan tray level, guide it into the carrier rails on each side and gently
push it all the way into the slot, ensuring that it firmly engages with the
connector.
5. When you are sure the fan tray has properly engaged the connector, tighten the
retainer screws to secure the fan tray in the slot.
Note: The fans are controlled by software, and their speed is set according to the
environmental temperature surrounding the switch.
