Installing the Replacement BlackDiamond 12804 Fan Tray

To install a replacement fan tray into the BlackDiamond 12802 switch:
1Attach the ESD-preventive wrist strap to your wrist and connect the metal end to the ground
receptacle on the top left corner of the switch.
2Support the bottom of the fan tray with one hand as you lift the fan tray by the handle using the
other hand. Align the spare fan tray with the fan tray slot on the switch, and then slide the fan tray
into place in the switch (see Figure 78).
CAUTION
Be sure that both hands are used to support the weight of the fan tray during installation.

3Use a #2 Phillips screwdriver to tighten the screws (Figure80).
Leave the ESD-preventive wrist strap permanently connected to the switch so that it is always available
when you need to touch ESD-sensitive components.

The BlackDiamond 12802 switch has one fan tray, which is accessible from the back of the switch.
CAUTION
Removing the fan tray for more than a few minutes may result in overheating and possible damage to the system.
