8.14.2 Adding/Replacing Boards
Except for the PowerCPU EE, any board can be plugged/unplugged when the system is powered
up.
To replace a PowerCPU EE board:
• Press the ON/OFF button, the
RED
led will flash.
• Wait for the LED to go to steady red (about 30 seconds): the system is turned off.
With OMC you can save and subsequently restore the configuration after replacing the PowerCPU EE
board.
Note:
A PowerCPU EE C25 can be replaced by a PowerCPU EE C25 only. Migration from a PowerCPU EE board to a
PowerCPU EE C25 board is not supported.
