1.10.4 Fan Modules

There are eight fan modules on the chassis for the leafs. They are located on both sides of
the chassis; four on the leaf side corners and four on the spine side corners. When a fan
module is not functioning the status LED on the fan will light up.
Each spine has an individual fan module that contains two individual fans. Should a sin-
gle fan fail the Fan Status LED on the spine and the S. Fan LED on the management
module will light, indicating the necessity to replace the fan module. Air flow through
the spines is independent of the air flow through the leafs.

numbers and are not interchangeable. The fans on the leaf side of the chassis are
MTF005001, whereas the fans on the spine side of the chassis are MTF005002.
