NBX IP Telephony Platforms 29
V3000 Analog The V3000 Analog ( Figure 1) houses the Network Call Processor (NCP),
which manages call traffic and NBX Messaging, the system disk drive and
power supply, and front panel connectors for network and external
device connectivity.
V3000 platforms come with 128 MB of memory. You must install an
optional memory upgrade to support some features. See
Table 13 on
page 63 for more information.
The 3C10600A is an earlier version of the 3C10600B V3000 Analog. The
function and the layout of the front panel connectors and LEDs is the
same for both models.
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:
