Impact on the System During Installation

Impact on Services

After you upload the patch firmware through the iBMC, the firmware is not upgraded immediately. When the server is powered off, the TEE OS firmware is upgraded. The upgrade takes about 1 minute. After the firmware upgrade is complete, the server can be powered on to run service applications.

Impact on Network Communication

Upgrade the firmware only when the server is powered off. For details, see "Impact on Services."
