The cooling system in an optical ILA consists of three 12.4-W fan modules. These fan modules can be
hot-swapped—you do not need to power off the optical ILA or disrupt the functioning of the optical ILA
to replace a fan module. The optical ILA has two 150-W power supplies, either AC or DC depending on
your configuration. The power supplies need to be both AC or both DC. Only one power supply is required
to power the device, while the second power supply provides redundancy.
