shadowed system

To expand from a 1-node to a 2-node shadowed system, follow

these steps.

You must properly courtesy down the system before you

can power down. For more information on courtesy down

Before you install the disk units, verify their jumper

settings. Refer to Chapter 12, “Configuring the Meridian 1.”

3 Remove the VP4 or VP8 cards from slots 0 to 3 as necessary,

and install them, along with the VPs supplied for expansion, as

follows:

a. Install 24 ports in slots 8 to 11.
