Replacing a fan tray
CAUTION:
•
To avoid injury, do not touch any wires, terminals, and parts with a high-voltage hazard sign.
•
Fan trays are hot-swappable. To replace a fan tray with the switch running, pull out the fan tray after it
stops rotating. Keep your hands away from the spinning fan blades when removing the fan tray.
•
To ensure normal operation of the switch, do not keep the switch working without a fan tray for a long
time.
•
When removing a fan tray, hold the bottom of the fan tray to pull it out thoroughly.
Preparing for the replacement
1.
Put on an ESD-preventive wrist strap, and make sure the wrist strap makes good skin contact and
is well grounded.
2.
Unpack the fan tray to be installed.
