12. Determine if you can remove the board safely at this time.
You can remove the board only if all of the LEDs are in the following states:
■
Amber Okay to Remove LED on the system status panel is on
■
Green Power LED on the system status panel is off
■
Blue Hot-swap LED on the board is on
It might take several seconds or minutes for the LEDs to transition to the proper
states.
For detailed information on states of the system status panel LEDs, see Section 4.1,
“Troubleshooting the System Using the System Status Panel” on page 4-2 . Do not
remove a board unless all of the LEDs are in the proper states. If you remove a board
when any of the LEDs are not in the proper state, the action might cause
unpredictable results.
Caution – Do not attempt to hot-swap any other boards or rear transition modules
until you see that the first board is fully deactivated. Hot-swapping more than one
board at the same time might lead to unpredictable results.
Note – If the server is set to the default full hot-swap mode, unlocking the ejection
levers automatically starts the
cfgadm unconfigure
operation. If you decide that
you do not want to remove the board, you must wait until the LEDs are in the
correct state (as shown in Step 12 ), completely unseat the board, reseat it, then lock
the ejection levers again to start the
cfgadm configure
operation. Simply locking
the ejection levers after unlocking them does not start the driver attachment process.
13. When it is safe to remove the board, disconnect any cables connected to the board.
14. Press outward on the two ejection levers on the board to unseat the board from
the board cage.
