Will I receive an alert email notification if my security
appliance experiences a hardware failure?
appliance experiences a hardware failure?
Yes, and no. Cisco security appliances have self−monitoring capabilities and can generate alert email
notifications when certain hardware conditions occur. These alert notifications can be controlled using the
alertconfig command.
notifications when certain hardware conditions occur. These alert notifications can be controlled using the
alertconfig command.
Using alertconfig, you can establish a list of email addresses to receive all alert messages generated by your
security appliance. You can also have copies of these alert messages sent to Cisco customer support, as well
as a weekly summary of the performance characteristics of your appliance.

Alert messages are designed to let you know about critical system issues that require some intervention.
Because alert messages are sent through a different email system running on the appliance, they can even be
sent when there are problems within AsyncOS.
Because alert messages are sent through a different email system running on the appliance, they can even be
sent when there are problems within AsyncOS.
The AsyncOS operating system generating alert messages has limited visibility into the underlying hardware.
While AsyncOS does have knowledge of the status of the disk I/O RAID subsystem, it does not have
knowledge of problems reported by the system motherboard itself, such as a fan or power supply failure. This
means that problems within the disk subsystem, such as failure of a disk drive or the requirement for a cache
battery replacement, will be sent via the alert system.

Other problems, such as fan failure causing overtemperature within the system, will not be sent via alerts.
Instead, these problems will be detected by the system BIOS and will be reported by the front panel display.
AsyncOS does not have the capability to trap and alert based on these errors.

On all security appliances, the front panel has a visible status indicator that can be in one of four states:
