SW Memory Banks
UHP software (SW) is placed in non-volatile flash memory. The built-in flash memory can contain up to three
different SW versions stored in so-called memory banks. The memory banks are numbered from 0 to 3. Memory
bank zero contains the boot-loader supporting selection of SW to be used and the configuration profile at startup.
By default, on its startup the router scans the memory banks and launches the first valid SW.
The equipment allows changing boot-loader settings, specifying the memory bank to be used on startup. When the
SW is updated, it is possible to check performance of the new SW on a temporary basis. The router will once load
the new SW and if any problem occurs (e.g. no connection) the router reboots after a while with the old SW. This
procedure is called “fallback”. If the user reboots the router while working with temporary software it will start
with its permanent SW from the main memory bank. To implement this mechanism one bank must be specified as
the main software storage and another memory bank – as temporary software storage.
The content of the Flash memory can be viewed in the Memory contents section (See Figure 47) and allows
downloading new SW (see Boot control section). This section is accessed by selecting Advanced -> System -> Flash
/ Boot in the Menu of commands.
To choose the bank that will be used upon startup follow Advanced -> System -> Flash / Boot and specify the
configuration bank number in Boot control section, Main boot -> Software bank setting (see Figure 47).
