Hot-Pluggable PCI Adapter
Removing a Hot-Pluggable PCI Adapter
Note: If you are removing an adapter and replacing it with an adapter that is identical to the adapter
removed, use the “Replacing a Hot-Pluggable PCI Adapter” on page 420 procedure.
To remove an adapter, do the following:
1. Place the I/O drawer in the rear service position:
a. If you have not already done so, open the front door of the rack unit.
b. Loosen the two thumbscrews that attach the front bezel to the drawer.
c. Grasp both sides of the front bezel and pull the bezel off the drawer.
d. If you have not already done so, open the rear door of the rack unit.
e. If present, remove the two retaining screws that secure the drawer to the rails. Refer to “Rear
Service Position” on page 463.
f. Ensure that the cables do not restrain drawer movement.
g. Grasp the bar at the rear of the drawer, and pull the drawer to the rear until it is stopped by the
detents.
2. Remove the two thumbscrews and remove the top cover from the drawer.
3. Determine the slot from which you are removing the adapter.
4. Ensure that any processes or applications that might use the adapter are stopped.
Note: Removing a hot-pluggable PCI adapter requires the system administrator to take the PCI
adapter offline before performing any PCI adapter hot-plug procedures. Before taking an
adapter offline, the devices attached to the adapter must be taken offline as well. This action
prevents a service representative or user from causing an unexpected outage for system
users.
For additional information about taking an adapter offline or removing it from the system
configuration, see the AIX System Management Guide: Operating System and Devices . This
publication is located on the AIX Documentation CD. The documentation information is made
accessible by loading the documentation CD onto the hard disk or by mounting the CD in the
CD-ROM drive.

to select PCI Hot Plug Manager . Then return here to continue.
