MX301 Field-Replaceable Units

Learn about the field-replaceable units in the MX301.

Field-replaceable units (FRUs) are components that you can replace at your site. There are two types of FRUs:

  • Hot-insertable and hot-removable—You can remove and replace these components without powering off the device or disrupting the device functions.

  • Hot-pluggable—You can remove and replace these components without powering off the device, but the device function is interrupted until you replace the component.
