A well-organized physical configuration can simplify:
Management of incoming telephone lines, by associating line card
■
ports with specific telephone numbers
Troubleshooting, by associating groups of channel numbers with
■
specific cards
System expansion
■
To determine the MAC address of the analog lines of the NBX V3001 or
V3000:
View the label on the back of the unit. The MAC address is labeled
■
FXO MAC Address. All four analog line ports share one MAC
address. After the ports are discovered by the NBX Auto Discover
process, they are differentiated in the NBX NetSet utility by a channel
number, 1-4.
To determine the MAC addresses of the ports on optional NBX Analog
Line Cards, NBX Analog Terminal Cards, and NBX Digital Line Cards:
View the MAC address label attached to each card. MAC address
■
labels are located on the component side of NBX cards. All four ports
on a card share one MAC address and they are differentiated by a
channel number, 1-4. After a card is inserted into a chassis, the MAC
address is not visible.
Verify that the equipment rack is properly installed and grounded and
that the installation area is properly ventilated. Use a standard 486-mm
(19-in.) equipment rack. Allow at least 8 cm (3 in.) of space on either side
of the NBX chassis for proper ventilation.
Install the two rack mounting brackets on the front sides of the NBX
system using the screws that came with the unit
Install the chassis into the rack. Be sure to tighten all four screws securely.
Disk mirroring is an option that is supported on the V5000 and the
V3001R. Disk mirroring provides the ability to run a second disk in parallel
with the first. Data is kept current on both disks. If one disk fails, the
second disk takes over without any system interruption. The primary disk
is already mounted in your V5000 or V3001R chassis. The second disk (if
