Fan Modules

There are four fan modules on the chassis for the leafs. They are located on both sides of
the chassis; two on the leaf side corners and two on the spine side. 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.
1.9.4.1 Leaf Fan Module
There are four leaf fan modules. Two leaf fan modules are found on the leaf side and two
leaf fan modules are found on the spine side.
The leaf side fans are not interchangeable with the spine side fans. Air flow through the
leafs is independent of the air flow through the spines.
