Replacing a fan tray
CAUTION:
• When you replace a fan tray from a running switch, be cautious
of electricity hazards, and do not touch the rotating fan to avoid
bodily injury.
• If a fan tray fails, finish replacing the fan tray within 5 minutes. If
both fan trays fail, finish replacing the fan trays within 3 minutes
to avoid switch damage.
IMPORTANT:
Make sure the new fan tray is the same model as the one to be
replaced.
To replace a fan tray:
1. Prepare an antistatic bag for the removed fan tray.
2. Wear an ESD wrist strap, and make sure it makes good skin
contact and is correctly grounded.
3. Use a screwdriver to loosen the captive screws of the fan tray. See
callout 1 in Figure 4.
4. Holding th
e handle of the fan tray, pull the fan tray out of the
chassis. See callout 2 in Figure 4.
5. Put the removed
fan tray into the antistatic bag.
6. Install a new fan tray. For more information, see "Installing a fan
tray."
