Seems like the "new" card may have an internal short in it.

BUT FIRST, where did you put the new card? at the end in an empty slot? or did you stick it in just anywhere? If you installed the card in a slot that had a different card before - you can screw everything up. You would have to do a board renumber - but that could also screw up all of your prior programming. So first, let us know how the system was set up (modules left to right) BEFORE you put in the new card. The describe the system (modules from left to right) AFTER you installed the new card - and maybe we can figure out what is going on.

Hi
What i did first was turn off the system and took out my old mlx 408 card and replace it with the 408 mlx ID and turn the system back on .

For the cards i have

MLX 408 408 for classic merlin phones and 12 ring gen just 3

Now when i put the new card the system turn on but the phones were dead

Thank for the help

If the card you removed was a 408 MLX - and that is where you put the new card - then it is most likely that your new 408 ID module is defective (has an internal short). If you put the new 408 MLX where there had been a 408 ATL card - then you would have to do a "frigid" start on the processor - for it to recognize the new MLX card in a slot previously occupied by a 408 ATL card.

So - if what you say is true - you have a "bad" 408 MLX ID module.

How do i do a frigid" start on the processor ?


Thank you very much

You would erase all programming done by doing a "frigid" start. If you did what you say you did - there is no need to do a "frigid" start. Your new 408 ID MLX module is probably defective.

But, for future reference, you can open up the Legend processor case. You will see two large oval battery-like objects close together. They will have blue tape around the edges. They are capacitors for programming backup. Just below them is a jumper clip. Remove it and leave it off for 20 seconds - then reinstall it. Put the processor case back together and reinstall the processor. Turn it back on - and it will show an "F" on the display - indicating a full erase frigid startup. If you reinstall it and turn it on with the "bad" MLX ID module still installed - it may do nothing at all - because of the possible short circuit.

Sometimes I have found a board renumber will resolve the issue.

Pull out that board. Check both the edge connector on the board and the backplane slot for debris. If both are clear, then reinstall the card and make sure it seats ALL the way in. If the symptoms persist, I would agree that the board is hosed.

BTW, it's true that board renumbering is the usual technique for getting the processor to recogonize a new card. However, boards added in the next available empty slot are frequently identified automatically after a reboot. Swapping like-for-like cards doesn't require this step, which is impossible anyway if the system is dead.

Side note: There has been a little debate about whether any difference exists between "frigid start" and "system erase". But I've never had any trouble after going to Maintenance, Slot, entering "00", Demand Test, pressing F3 twice (hidden option), then responding "Yes" to the System Erase prompt. This technique also produces an "F" on the processor during boot, indicating a frigid start.

Using the "maintenance" routine to do a "frigid" start is equivalent to pulling off the jumper for 20 seconds. I only use the jumper method when you cannot access system programming from the 20L or WinSPM - which does happen if the admin port is "bad" and/if there is a mismatch in the installation order of the cards from when the system was last used.

I agree a board renumber should not be required for a like for like board. I have seen it on numerous occasions fix the issue. It is worth the 5 seconds a board renumber takes to test.
