Unpacking and Examining the Components 93 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. Optional NBX Cards ■ To determine the MAC addresses of the ports on optional NBX Analog Line Cards, NBX Analog Terminal Cards, and NBX Digital Line Cards,
