Fan Modules

The fan modules in an optical ILA are hot-removable and hot-insertable FRUs. These fan modules can be
hot-swapped—you do not need to power off the optical ILA or disrupt the optical ILA function to replace
a fan module. The fan module slots are numbered 0 through 2 from left to right when viewing chassis from
the FRU panel side (see Figure 11 on page
ILA. The numbers are located on the top of the chassis.

NOTE: All three fan modules must be installed for optimal operation of the optical ILA. The
optical ILA continues to operate for a period of 30 seconds during the replacement of the fan
module without thermal shutdown.
