Chapter 2. Installation and configuration.
2.1. Configuration L-502.
Here, the hardware settings of the L-502 are considered, which must be done before the L-502
module is installed in the computer. These settings are made by jumper, which you need to put (or
not) on the corresponding pair of contacts, indicated below in the tables with conditional numbers.
2.1.1. Backup boot configuration

Jumper for
1-2
FPGA is loaded with the main firmware from the
Flash-memory.
This loading mode is considered the main mode,
and the L-502 always comes with a jumper set to
contacts 1-2.
No jumper FPGA is loaded with a backup copy of the
firmware from Flash-memory.
This loading mode is considered auxiliary and the
user can apply it if, for some reason, the main flash
memory firmware has been corrupted and, as a
result, the L-502 device has ceased to be detected
by the operating system. See Note
.
Note
: Putting or removing the backup jumper should be done with the computer system's
completely de-energized computer (the usual shutdown of the computer - the software or the button
at the front of the system unit - is not enough, since the system unit has the "standby" power)
