1. You can upgrade the CPLD and BMC on the BMC plane, and upgrade service
software on the Base and Fabric planes.
2. The total capacity of the /tmp directory to which an upgrade file
is uploaded is .The available capacity is
3. The Base and Fabric planes must be restarted after upgraded to a later
version, but patch installation does not require a restart.
4. Restarting a switching plane interrupts all links on the plane. Exercise
caution and avoid restarting all switching planes at the same time.
5. Restarting the primary switching plane in a stack will restart all
switching planes in the stack.
6. After switches are stacked on the Base or Fabric plane, you need to
upgrade only the master switch in the stack. After the master switch
is upgraded, it automatically upgrades the standby switch and slave
switches.
7. Do not refresh the page or close the web browser during an upgrade.
8. Upgrading the CPLD of a switch module automatically restarts the BMC
