This article discusses a possible cause of the FortiGate interface status remaining 'down' after a power outage.
Scope
Any supported version of FortiOS.
Solution
In some cases, especially with FortiOS 6.4.X, the FortiGate interface's status stays as 'down' after a power outage.
The error message 'NP6: Switch INIT TIMEOUT, NP6 driver init failed!' shows in the console logs and/or COMlog after the recovery from the power outage. This issue occurs when the FortiGate disk scan takes a longer time. Normally, FortiGate must scan the disk after a power outage.
To fix the issue, perform the following steps:
Soft-reboot FortiGate using the 'execute reboot' command.
Upgrade FortiGate to one of the v7.2.x , v7.4.x or v7.6.x firmware, or a later release.
