CAUTION:
•
If you insert the fan tray with the upside facing downward, you
cannot completely insert the module into the slot. If this happens,
pull the fan tray out and then insert it again with the upside on
top.
• If you cannot fix the captive screws, check whether the fan tray is
correctly installed.
Replacing a fan tray
CAUTION:
•
When replacing a fan tray from a running switch, be cautious of
electricity hazards, and do not touch the rotating fans to avoid
bodily injury.
• After you unplug a fan tray from a running switch, install a new
fan tray within six minutes to ensure proper ventilation and heat
dissipation of the switch.
When the fan tray is faulty, you must replace it.
Follow these steps to replace a fan tray:
Step1 Prepare an antistatic bag for the removed fan tray.
Step2 Wear an ESD-preventive wrist strap, and make sure that it
makes good skin contact and is properly grounded.
Step3 As shown in callout 1 of Figure 5 , use a screwdriver to loosen
the captive screws of the fan tray.
