Replacing a fan tray
CAUTION:
To avoid bodily injury, do not touch the rotating fans when replacing the fan tray.
When the fan tray fails, replace the fan tray to ensure normal operation of the gateway.
The fan tray removal and installation procedures for all M9000 gateways are the same, even though the
fan tray slot is vertically oriented for the M9006 and M9014 gateways and horizontally oriented for the
M9010 gateway. This section takes removing and installing a vertically oriented fan tray on an M9006
as an example.
Removing a fan tray
CAUTION:
To ensure normal ventilation, install a new fan tray within two minutes after removing the old one.
To remove a fan tray:
1. Prepare an antistatic mat to place the fan tray to be removed.
2. Loosen the captive screws on the fan tray, as shown in callout 1 on Figure 36 .
3. Hold the handle of the fan tray with one hand to gently pull the fan tray part way out of the chassis.
After the fans stop rotating, support the bottom of the fan tray with the other hand, and take out the
fan tray from the chassis, as shown in callout 2 on Figure 36 .
4. Put the removed fan tray on the antistatic mat.
