Removing fan modules

Use the instructions to remove fan modules from the Flex System Carrier-Grade chassis, depending on the type of fan module.

Attention:
  • Do not operate the chassis for an extended period of time without both 40 mm fan modules installed. If you remove a 40 mm fan module, install a new 40 mm fan module within 5 minutes to maintain adequate cooling.
  • Do not operate the chassis without a 80 mm fan module or a 80 mm filler in each 80 mm fan bay. When you remove a 80 mm fan module in a typical environment, install a new 80 mm fan within 2 minutes to maintain adequate cooling. In an extreme environment, you must install a new 80 mm fan within 30 seconds to maintain adequate cooling.
  • Both the 40 mm and 80 mm fans can be hot swapped. It requires an estimated 15 seconds to remove and replace a fan module.
