Removing Adapter Cards
With this system, you can remove PCI adapters with the power on. These adapters are
referred to as hot–pluggable PCI adapters. Some adapters are not hot–pluggable and
power must be removed from the system for adapter removal.
Before you remove an adapter, determine if the PCI adapter you are installing is
hot–pluggable. See the PCI Adapter Placement Reference, on Appendix C. Also, review the
information in ”PCI Adapter Options” on page 3-7.
If you are removing a PCI adapter that is:
• Not hot–pluggable, continue with ”Removing a Non–Hot–Pluggable PCI Adapter” on
page 3-11.
• Hot–pluggable, go to ”Removing/Replacing a Hot–Pluggable PCI Adapter” on page 3-12.
Removing a Non–Hot–Pluggable PCI Adapter
Perform the following steps to remove a non hot–pluggable adapter:
1. If you have not already done so, shut down the system as described in ”Stopping the
System Unit” on page 3-2.
2. If you have not already done so, unplug the system unit power cable from the electrical
outlet.
3. If you have not already done so, remove the front, rear, and left covers as described in
”Removing the Covers” on page 3-4.
4. Determine the slot from which you are removing the adapter.
5. Disconnect any cables that are connected to the adapter being removed.
6. Turn the locking latch and lift the plastic stop for the adapter.Some full–length adapter
cards can be removed by rotating the blue adapter latch on the right end of the adapter
divider clockwise.
7. Carefully grasp the adapter by the edges and pull it straight out from the system board.
Store the adapter in a safe place.
