Tools and Equipment
Obtain these necessary tools and equipment:
Ratcheting torque screwdriver with a number-2 Phillips head that exerts up to 15 pound-force inches
(lbf-in.) or 240 ounce-force inches (ozf-in.) of pressure.
Installation Guidelines
Observe these guidelines when removing or installing a fan module:
• Do not force the fan module into the slot. This can damage the pins on the switch if they are not
aligned with the module.
• A fan module that is only partially connected to the switch can disrupt the system operation.
• The switch supports hot swapping of the fan module. You can remove and replace the module
without interrupting normal switch operation.
• When replacing the fan module, complete the replacement procedure within 2 minutes to avoid
overheating the switch.
• Make sure that all fan module captive screws are tightened before moving the switch.
