Removing a hot-plug memory board
Note: If you remove a memory board from the server, you must
either replace it with a new memory board or install a memory
board air baffle.
1 Observe the ESD precautions described on page 33.
2 Press the attention button on the memory board. The power LED
will begin to flash. Refer to "Memory board LED indicators" on
page 21 for the location of the power LED.
3 After the hot-plug attention LED stops flashing, make sure the
power LED for the memory board is also off.
Caution! Do not attempt to remove any memory board while any
of the LEDs are either on or blinking. If the attention LEDs do not
turn off, your configuration may not support hot-plug memory
board activity. For instructions on non-hot-plug memory board
maintenance, see "Cold removal of memory board" and "Cold
insertion of a memory board".
4 Once all the board LEDs are off, press the latch on the memory
board handle to release the handle (A) and lift the handle up (B).
5 Lift the memory board from the server (C).
