Question : Pix 515e failover

I am having problems getting failover to work.

I have One PIX 515e UR and one PIX 515e restricted. Both are running 7.0(1).  I configured the UR PIX and everything is running well for a year now. I purchased a second restricted PIX.  I connected the cable between the two firewalls, then enabled failover on the primary, and then booted up the second pix after cabling everyting.

Did I miss something?  It will not failover.

Answer : Pix 515e failover

>I have One PIX 515e UR and one PIX 515e restricted
  Sorry, but a PIX with a Restricted license can't be used as a failover partner (neither primary or secondary).  You'd need one that's either got a UR or a FO (Failvoer) license.
