you purchased one) is packaged separately for you to install. If you are
not installing a second disk with your NBX system, you can skip this
section and proceed to
“Powering Your NBX System” on page 98 .
Disk Mirroring is enabled when you install the disk mirroring license key
in the NBX NetSet utility. The NBX NetSet utility prompts you to reboot
the system after you install the license key to activate mirroring. To
disable mirroring, you must remove the mirroring license.
Always perform a system backup that includes your licenses and voice
mail before you make a hardware change. Be sure to copy the backup file
to a remote location. When you install a second drive for disk mirroring,
the system automatically synchronizes the disks, but it is still good
practice to perform a data backup before you begin the operation.
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 check the status of the disk system:
1 Login to the NBX NetSet utility as administrator.
2 Click Reports > System Data .
3 Scroll to the bottom of the System Data screen and click the Disk Status
button.
Disk Mirroring is an optional feature. If you do not install a second disk
when you first install your system, you can purchase an upgrade kit at a
later time.

second disk when you are setting up your NBX system:
