Replacing External Compact Flashes

The external compact flash is an optional component on J2320 and J2350 Services
Routers. It provides secondary storage for the router and can accommodate software
images, configuration files, and microcode. If the internal compact flash fails on
startup, the router boots from the external compact flash.
For information about configuring the external compact flash, see the JUNOS Software
Administration Guide.

external compact flash. If no external compact flash is installed, proceed directly to
Step 10 to install the compact flash.
