Replacing Hardware Components
Most of the router's hardware components are field-replaceable units (FRUs), which
means that you can remove and replace them yourself. When you need to replace
a router component, contact your customer support or sales representative to order
the field-replaceable unit (FRU) that contains the component. For instructions, see
“Contacting Customer Support and Returning Hardware” on page 189. For a list of the
FRUs on the M10i routers, see “Field-Replaceable Units (FRUs)” on page 3.
