Replacing a fan tray

Follow these restrictions and guidelines when you replace a fan tray:
•
To avoid bodily injury, do not touch the rotating fans when you replace the fan tray.
•
For good heat dissipation, you must install fan trays in both FAN1 and FAN2 slots. When a fan
tray fails, do not remove it until the new fan tray is ready. The device can operate correctly if the
failed fan tray is still in position.
•
The fan tray is hot swappable. Follow these guidelines when you hot swap a fan tray:
Ensure electricity safety.
Replace a fan tray only when the other fan tray is operating correctly.
To avoid power-off protection of the switch caused by high temperature, finish replacing a
fan tray within 3 minutes.
•
Do not power on a switch that does not have any fan trays installed.
•
Remove the fan tray before you install or replace a switching fabric module. Install the fan tray
immediately after you finish installing or replacing the switching fabric module. Prepare in
advance to make sure the whole process is finished within 3 minutes.
