Disk mirroring provides the ability to run a second disk in parallel with
the first. For more detailed information about disk mirroring, see "Disk
Mirroring" in the NBX Administrator's Guide.
Disk Mirroring is an optional feature. If you do not install a second disk
when you first install your Network Telephone System, you can purchase
an upgrade kit at a later time. If you are not installing a second disk with
your Network Telephone System, you can skip this section and proceed to
"Powering Your SuperStack 3 NBX System"
This section describes how to install your second disk when you are
setting up your NBX system. While the primary disk is already mounted in
your Network Call Processor chassis, the second disk (if you purchased
one) is packaged separately for you to install.
CAUTION: To avoid damage to electronic circuits, always wear an
anti-static grounding strap when handling the disk drive or NBX system
components. When you ground the strap, do not ground it to an
NBX chassis because the chassis is not grounded until you install it in a
properly grounded setting.
To install an additional disk drive for disk mirroring:
1 Install the key code for your disk mirroring license.
2 Shut down system software.
3 Turn off power to your system. If your SuperStack 3 NBX Call Processor
has redundant power supplies you must disconnect both supplies.
4 Remove the disk drive tray on your Network Call Processor.
5 Unpack the second disk drive and install it in slot number 2 of the disk
tray.
6 Connect the ribbon cable correctly.
7 Re-insert the disk drive tray.
After you add power to the system, disk synchronization begins
automatically and finishes in approximately 60 to 90 minutes, depending
on the amount of information on disk 1 that must be mirrored on disk 2.
