4x10G card is PPA3 based
1x10G card is PPA2 based

In 12.1.1.7p1 ericsson has resolved important crash problem for PPA3 
based cards, while PPA2 cards problems still exists.

So, if you have only PPA3 based cards - use 12.1.1.7p1
Also several other issues have been fixed.

If you have a very heavy load in meaing of fetures and functions on a 
single node, probabilty of crash increases.. on a SE600 that acts as a 
BGP only - 12.1.1.5p2 and no crashes on record..


btw, as additional workaround for any possible future crashes - use 2x 
4x10G cards and create link-groups access mode (cross cards). In a case 
of a crash (single card crash) the other card in link-group continues 
operation with a little hiccup for switchover. No multiple simultanous 
crashes occur.

Regards,
Marcin
