The fan tray is installed horizontally on the rear of the chassis.
Before you remove a fan tray:
•
Ensure you understand how to prevent ESD damage. See
Ensure that you have the following parts and tools available to remove a fan tray from
the switch chassis:
•
Electrostatic discharge (ESD) grounding strap
•
Replacement fan tray
•
An antistatic bag or an antistatic mat
CAUTION:
The fan tray can be removed and replaced while the switch is
operating. However, the fan tray must be replaced within 30 seconds of
removing the fan tray to prevent overheating of the chassis.
To remove a fan tray from the switch chassis (see
):
1.
Place the antistatic bag or the antistatic mat on a flat, stable surface.
2.
Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and
connect the strap to the ESD point on the chassis.
3.
Squeeze both handles of the fan tray to release the latches that lock the fan tray in
the chassis.
WARNING:
To avoid injury, do not touch the fans with your hands or any
tools as you slide the fan tray out of the chassis—the fans might still be
spinning.
4.
Grasp the handles on the fan tray and pull firmly to slide the fan tray halfway out of
the chassis.
5.
When the fan stops spinning, slide the fan tray completely out of the chassis.
6.
Place the fan tray in the antistatic bag or on the antistatic mat placed on a flat, stable
surface.
