The SPA will go out of service in this instance if the SPI4 synchronization fails 5 times. This can be the result of a mis-seated card or a hardware failure. Please try the following -
1) First, re-seat the SPA in the same slot that it is currently in to see if it comes back online.
2) If it doesn't, try to insert the SPA in a different slot of the same SIP if any are available.
3) If this still fails, try to insert the SPA into a different SIP if possible to see if it comes online there.
If the SPA comes online in a different slot of the SIP but fails in the current slot, this is likely a hardware issue with the SIP. If it fails to come online at all, this is likely a problem with the SPA. Hope this helps.
