Optical ILA Field-Replaceable Units
Field-replaceable units (FRUs) are components that you can replace at your site. The optical ILA FRUs are hot-removable and hot-insertable—you can remove and replace them without powering off the optical ILA or disrupting the optical ILA function.
Replace a failed fan module with a new fan module within 30 seconds of removal to prevent chassis overheating.
Table 1 lists the FRUs for the optical ILA and actions to take before removing them.

If you have a Juniper Care service contract, register any addition, change, or upgrade of hardware components at https://www.juniper.net/customers/support/tools/updateinstallbase/. Failure to do so can result in significant delays if you need replacement parts. This note does not apply if you replace existing components with the same type of component.
