Maybe the card is bad or not set properly causing the failover? Try resetting it. Does it have the latest firmware?

Just realized it is integrated as per eeRoot.

Recently, we received the following error on our primary ASA5515-X which caused the unit to failover to the secondary ASA (same model) - &nbsp;&quot;%ASA−1−104001: (Secondary) Switching to ACTIVE − Service card in other unit failed&quot;<br />
<br />
The interesting thing here is that we have NO IPS purchased or configured in either model. There is however AVC (Application visibility and control) and WSE - Web Security Essentials (URL Filtering) on both, but never been setup or used. The ASAs have been running for about 2 years without issue.<br />
<br />
We were able to fail back to the primary without making any changes. Thoughts?

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
