In rare occurrences, the Baseboard Management Controller (BMC) might fail to initialize while booting up.
The BMC status displays during the BIOS POST check output:
The Baseboard Management Controller (BMC) is a chip on the S500, S400, and S200 series motherboards that supports the Intelligent Platform Management Interface (IPMI) specification.
Sensor values are gathered by the BMC and stored in the Sensor Data Register (SDR).
The operating system will then read the SDR and report the values, including if any critical preset thresholds have been exceeded.
The following examples show the serial output for a S200, S400 and S500 where the BMC failed to initialize:
The BMC failing to initialize has been fixed in updated BMC firmware for all the S-Series models (S200, S400 and S500).
The ability to upgrade the BMC firmware has been added to hardware diagnostics version 184.108.40.206 or later for S-Series appliances.

To reset the BMC, it is necessary to power down the appliance, disconnect all power cords, and wait 30 seconds.
After waiting 30 seconds, reconnect the cords and restart the unit.
For appliances that have a CLI shutdown command, use this command to gracefully shut down the unit.
WARNING: Abruptly removing power on these systems can result in irreparable data loss.
|Model||Products with CLI shutdown command|
|Advanced Secure Gateway|
|S400||ASG-S400||Advanced Secure Gateway|
|MTD-S400||Mail Threat Defense|
|ASG-S500||Advanced Secure Gateway|
NOTE: When a CLI shutdown command is used to power down the appliance, the unit will NOT automatically power on after the power cords are reconnected.
To turn the unit on, press the power switch on the rear of the appliance.
