12V-PWR (12 Volt Power Supply)
The 12 Volt Power Supply unit in the TN777B NETCON circuit pack is required for
programming flash memory devices in circuit packs such as the TN786B or
TN790 Processor circuit pack and the removable translation card. During the
erase and write operations of a flash memory or translation card, the 12 volt
power supply must be turned on under the instruction of software. For the
read-only operation, the 12 volt power supply is not required.
If the 12-volt power supply cannot be turned on, all the erase and write
operations to a flash device fail. Features such as "save translation," "save
announcements," "system upgrade," "hard patching," and "core dump" always fail
in this case.
