2.3.6 Power-Up Details
WARNING: The Main Chassis redundant power supplies are NOT auto-ranging
like the IFD. These are factory configured for the expected voltage, but should
be VERIFIED by the customer before power is applied to the system.
When the RVP8 is powered–up or reset, the host Linux PC goes through an automated boot
process that ultimately starts the RVP8 application. The RVP8 then runs extensive internal
diagnostics. In most cases, there is no display connected to the RVP8 to monitor the boot
sequence. For troubleshooting it is useful to connect a display to view any error messages.
The RDA front panel display shows the status of the Linux boot sequence and summary status of
the diagnostic self-tests. During the Linux boot stage, the front panel shows the following which
indicates how much time has elapsed since the start of the boot process.
–––––––––––––––––––––––––––––––
| SIGMET Inc. Open RDA |
| Boot < 00:24 > |
–––––––––––––––––––––––––––––––
After the Linux boot process is complete, the RVP8 runs its internal self-tests during which the
front panel display appears as follows.
–––––––––––––––––––––––––––––––
| RVP8 V4.3 Starting |
| Running Diagnostics |
–––––––––––––––––––––––––––––––
After successful completion of the self-tests, the display will show the following,
–––––––––––––––––––––––––––––––
| RVP8 V4.3 Starting |
| Diagnostics Pass |
–––––––––––––––––––––––––––––––
and then switch to the standard operational display which shows the current azimuth and
elevation, the major mode, the number of range bins, the PRF and XXX:
–––––––––––––––––––––––––––––––
| 179.23 AZ/EL 14.96 |
| FFT 1646 1800 Hz x1 |
–––––––––––––––––––––––––––––––
In the event that the diagnostics do not pass, then the display will indicate the number of tests
that “Fail”. Note that the “dspx –nochat” utility “gparm” command or the “v” command in the
TTY setups can be used to learn the details of the failures.
