Installing/removing fan trays

CAUTION:
The switch has four fan tray slots. To ensure good ventilation of the switch, follow these guidelines to
install and remove fan trays:
• The switch comes with the fan tray slots empty. For adequate heat dissipation of the switch, fully
configure the switch with fan trays of the same model. If the number of installed fan trays is less
than the minimum required number, the device will output an error message and does not power
up.
• Make sure all slots have a module or filler panel installed when the switch is operating.
• If multiple fan trays fail on an operating switch, do not remove the fan trays at the same time.
Replace the fan trays one after another and finish replacing a fan tray within 3 minutes.
CAUTION:
• Do not touch any bare cables or terminals on the fan tray.
• Do not place the fan tray in a wet area, and prevent liquid from entering into the fan tray.
• When an internal circuit or component of the fan tray fails, contact H3C Support. Do not remove
any component from the fan tray yourself.
The installation and removal procedures are the same for fan trays of different models. The following
installation and removal procedures use the FAN-40B-1-C fan tray as examples.
