V3000 platforms come with 128 MB of memory. You must install an optional memory upgrade to support some features. See Table 13 on page 60 for more information. The 3C10600A version of the V3000 Analog is no longer available. The system has been updated to 3C10600B. It includes a new front panel and updated internal components. The function and the layout of the front panel connectors and LEDs is the same for both models.
