I. Replacing the fan tray of S9505/S9508/S9512
1)
Wear the ESD-preventive wrist strap. Remove the captive screws on both sides of
the fan tray. Gently pull the fan tray out of the slot along the guide rails, as shown
in Figure 5-8.
Caution:
When you replace the fan tray on an operating switch, pull the fan tray half way out of
the chassis to disconnect the power, and wait till the fans stop rotating before pulling it
out completely. Considering that the fans may be still rotating, avoid stretching your
hands into the fan tray.

Replace the fan tray (1)
2) Slide the new fan tray smoothly along the guide rails until it fits into the chassis,
with its plug fully touching the socket inside the chassis.
Caution:
Do not turn the fan tray upside down. Otherwise, you will not be able to fully insert it into
the chassis due to the mis-plug prevention design of the chassis.
