things to know about the AM++
How to insert it
If you don't do it the right way you may stripp off capacitors from the bottom.
Basically you HAVE to keep the board pushed a little bit to the right in order to keep it away from the front-panel of its left board that could strip off parts.
Get trained on how to insert/remove AM++'s!!!
What to check before putting it in
1) Check the 4jumpers, in a single block, located near the bottom right corner of the board. They set the board number 0 or 1. You should choose 0 or 1 depending on which board you are replaceing.
2) Check that all 3 main board fuses are installed. They are located near the P0 connector, i.e. the smallest of the 4 connectors on going to the backplane.
If you have time also check whether they are all good.
3) When you power on the board check the front panel LEDs.
All 3 power LED's should be on: 5V, LAMB PWR, 3.3V.
One of the two bottom LED's should be on. It is telling you the board number.
Know problems or issues
- Be careful when sliding the AM++ into, out of, a crate (see above).
- If the board does not coldstart, check the LED's.
- Always make sure that all 3 main board fuses located near the P0 connector are installed. Since two of them are used for the 3.3V power the board could work even without one of them. Sounds cool? The problem is that if one of those is missing, or it is burned, the board seems working but the power is critical and you could get funny behaviours.
