Services Routers Hardware Guide

Chapter 8
Replacing Hardware Components
Because many of the Services Router's hardware components are field-replaceable
units (FRUs), 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 169.
