Removing the Virtual Buffer Memory Module
If you are upgrading an ARE processor module from 16 MB to 32 MB or 64 MB,
you must first remove the existing VBM module before you can install the new
one.
If you are upgrading from 8 MB to 32 MB, there is no VBM module to remove. In
this case, go to the next section, “Installing the Virtual Buffer Memory Module.”
To remove the existing VBM module, you must first remove the ARE processor
module from the router. Refer to Installing and Maintaining BN Routers for
instructions on replacing a FRE
®
/FRE-2 module.
To remove the VBM module:
1.
Turn the ARE module over (component side down) and place it gently on
your work surface.
2.
Remove the Phillips screws from each of the four mounting holes.
