(NCP), which manages call traffic and NBX Messaging, the system disk
drive and power supply, and front panel connections for 8 BRI channels (4
Ports), 2 ATC channels, and network connectivity. See
“NBX Licensing”
on page 59 for more information on the total number of supported

The first two BRI ports are enabled by default, the second two ports
require an optional software license.
CAUTION: Do not disconnect power during a system boot operation
after a software upgrade. On rare occasions, a system software upgrade
includes an upgrade to the system's flash memory image. The flash
upgrade occurs during the boot operation following a system software
upgrade. If you disconnect power during the flash upgrade, the boot
software may become corrupted and the system will need to be returned
to 3Com for repair. As the flash upgrade progresses, the system Console
displays these messages:

at a time is active. Typically, you would connect each port to a
different switch and subnet.
