Unpacking and
Examining the
Components
Unpack the system components and examine them. Depending on the
size and configuration of the system that was ordered, there may be
multiple chassis and line cards. If you have not received all components,
contact your 3Com NBX Voice-Authorized Partner.
Installing the
NBX System
Hardware
Before you begin to install the hardware, you can perform optional steps:
■
Recording MAC Addresses

Optionally Upgrading NBX Memory
Recording MAC
Addresses
After you install the system disk drive, you should record the MAC
addresses of the ports that interface with CO equipment. If you will be
installing optional cards into a chassis, 3Com recommends that you install
one card at a time, and that you install the cards in the order of the MAC
addresses of the ports on the card. This process ensures that the NBX
system assigns sequential, contiguous groups of device extensions to
each board. If you enable the Auto Discover process to configure the
cards, you can then use the NBX NetSet utility to view the MAC address
of each individual port.
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
V3000
■
To determine the MAC address of the analog lines of the NBX V3000,
view the label on the back of the NBX V3000. 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.
