How to simulate system power cycle in remote without physically unplug power cords?

Purpose:

This is a workaround primary for the timing when SOC NIC after firmware upgrade or downgrade.

Power cycle is always required for this kind cases. The method prevents you to send someone in fields for physically unplugging and plugging power cords.

Target Audience:

1. Who has well experience on Linux OS and IPMI utility.

2. System platforms designed with CPU integrated Ethernet ports, such as FWA-3050, FWA-3051...

Steps:

1. Connect system IPMI port or the Ethernet ports can access BMC to a network environment.

2. (Target system) Assign an IP address via BIOS or in Linux OS for accessing BMC.

3. (Target system) Gracefully shut down the system.

# poweroff

4. (The other system) Install IPMI tools.

5. (The other system) Access the IP address via IOL, then run the command.

# ipmitool -I lanplus -H {IP address} -U {BMC username} -P {BMC password} raw 0x06 0x52 0x05 0x82 0x00 0x00 0x08

6. Wait at least 10 seconds.

7. (The other system) Access the IP address via IOL, then run the command.

# ipmitool -I lanplus -H {IP address} -U {BMC username} -P {BMC password} raw 0x06 0x52 0x05 0x82 0x00 0x00 0x00

8. (The other system) Access the IP address via IOL, then you may power on target system.

# ipmitool -I lanplus -H {IP address} -U {BMC username} -P {BMC password} raw power on
