Figure 6-3 Install a fan tray
1) Wear an ESD-preventive wrist strap and loose the captive screws on the fan tray.
Caution:
If you want to replace the fan tray of an in-service switch, separate the fan tray from the
backplane to disconnect the power and wait till the fan stops rotating before pulling it
out completely. Considering that the fan may be still rotating, avoid stretching your
hands into the fan tray.
2) Slide the fan tray out of the slot.
3) Put the removed fan tray into the package.
4) Take out a new fan tray from the package. Slide the fan tray along the guides into
the slot until the frame is seated in the backplane of the switch.
5) Fasten the captive screws.
