Cisco VPN 3000 Concentrator displays the CPU power status as ALARM

Core issue

The CPU status on the Monitoring | System Status | Power screen appears as ALARM instead of OK. This problem can occur when the power thresholds are configured incorrectly.

Resolution

To resolve this problem, configure the thresholds correctly on the Configuration | Interfaces | Power screen. Refer to this table to configure the thresholds correctly:
