Removing I/O Modules
3 Simultaneously rotate the ejector/injector handles outward to disengage the module
from the backplane.
4 Slide the module out of the chassis.
5 If you are not going to install a replacement I/O module, cover the slot with a blank
faceplate. Otherwise, follow the I/O module installation procedure above.
6 Repeat this procedure for additional modules, if applicable.
7 Leave the ESD strap permanently connected to the chassis, so that it is always
available when you need to handle ESD-sensitive components.
