Use the instructions to replace fan modules in 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.
