V3001 Analog The V3001 Analog (3CR10800, 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.
V3001 platforms come with a base memory configuration. You must
install an optional memory upgrade to support some features. See
Table 13 on page 63 for more information.
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:
