a. Hold the board by the handle vertically with one hand. Place the other hand under the bottom
mounting rail.
b. Install the board in the chassis by tipping the handle of the board down so that the bottom rail meets
the bottom chassis guide rail.
c. When the bottom board rail is in the chassis guide rail, tip the board back up and align the top rail
into the chassis rail guide.
d. Slide the board into the chassis slowly until the ejector lever handles start to collapse inward.
3. Simultaneously rotate both ejectors until they are in the closed position (flush with the board).
When properly installed, the ejectors will lock automatically.
Note – The board will not be recognized by the system until the domain has been dynamically reconfigured
to include the board, or re-initialized and rebooted.
4. Reconfigure the CPU/Memory board back into the system by either of the two following procedures:
Dynamically reconfigure the CPU/Memory board into the domain.
Refer to the dynamic reconfiguration manual for your product.
Power on the board and initialize the domain.
Refer to the system administration manual for your product.
