Removing a Hot-Swap Module
This section describes a recommended procedure for removing a board
module from a chassis.
Before you remove your module, please read all cautions, warnings, and
instructions presented in this section and the guidelines explained in
Before You Install or Remove a Board
Hot swap compliant modules may be removed while the system is
powered on. If a module is not hot swap compliant, you should remove
power to the slot or system before removing the module. See
for more information.
To remove a board module, follow these steps:
1. Loosen the module’s captive screws at both ends of the faceplate.
2. Begin to remove your module by unlatching the ejector lever closest
to the blue LED (the lower lever on vertically mounted boards). See
Recognize Different Injector/Ejector Lever Types
. Do
not remove the module immediately.
!
Caution
Powering down or removing a board before the operating system or other
software running on the board has been properly shut down may cause
corruption of data or file systems.
If your module is hot swap compliant and you are running fully functional
hot swap-aware software, unlatching this ejector lever will start the
shutdown process on the board. Software will illuminate the blue hot swap
LED on the faceplate when it is safe to remove the board.
If your board or system is not running hot swap-aware software, the
blue LED may illuminate without regard to software processes still
running on the board. Be sure to manually shut down applications
or operating systems running on the board prior to board removal.
See
for more information.
3. Once the applications and operating system running on the board
have stopped and it is safe to remove the board, open both ejector
levers to partially unseat the module from the backplane connectors.
