Hot-Pluggable PCI Adapter
Replacing a Hot-Pluggable PCI Adapter
Note: Use this procedure only when you are replacing an adapter with an identical
adapter. If you are replacing an adapter with an adapter that is not identical to
the adapter removed, go to “Removing a Hot-Pluggable PCI Adapter” on
page 436 and “Installing a Hot-Pluggable PCI Adapter” on page 435.
To replace an adapter, perform the following steps:
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 467.
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
