Replacing a PCI adapter in the 8203-E4A, 9407-M15, or 9408-M25 server, with the power on in Linux

You can replace a PCI adapter with the system power on in the Linux operating system.

You must have already completed the procedure Removing a PCI adapter from the 8203-E4A, 9407-M15, or 9408-M25 server, with the power on in Linux.

If your system is managed by the Hardware Management Console (HMC), use the HMC to complete the steps for replacing a PCI adapter. For instructions, see Replacing a part by using the Hardware Management Console. If you do not have an HMC, complete this procedure to replace a PCI adapter.

If your system is managed by the IBM® Systems Director Management Console (SDMC), use the SDMC to replace the PCI adapter in the server. For information about using the SDMC to replace a PCI adapter, see Replacing a part by using the Systems Director Management Console. If you do not have an SDMC, complete this procedure to replace a PCI adapter.

To replace a PCI adapter with the system power on in Linux, do the following steps:

Perform the prerequisite tasks described in Before you begin.
Take appropriate precautions for avoiding electric shock and handling static-sensitive devices. For information, see Avoiding electric shock and Handling static-sensitive devices.
If necessary, remove the adapter from the antistatic package.
Attention: Avoid touching the components and gold connectors on the adapter.
Place the adapter, component-side up, on a flat, static-protective surface.
Run the drslot_chrp_pci command to enable an adapter to be replaced:
For example, to replace the PCI adapter in slot U7879.001.DQD014E-P1-C3 run this command:
```
drslot_chrp_pci -R -s U7879.001.DQD014E-P1-C3
```
Follow the instructions on the display to complete the task.
Install the adapter in the system unit as shown in the following figure and steps:
Figure 1. PCI adapter installation
1. Carefully grasp the adapter (C) by its top edge, and align the adapter with the expansion slot and its connector on the system backplane.
2. Firmly press the adapter connector into the slot.
3. If applicable, close the long-adapter, front retention bracket (D). This step only applies to long, PCI-X adapters.
4. Slide the adapter latch assembly (B) into the closed position. Press down on the assembly until latch (A) engages.
Connect the adapter cables.
Run the lsslot command to verify that the slot is occupied.
For example, enter lsslot -c pci -s U7879.001.DQD014E-P1-C3
The following is an example of the information displayed by this command:
```
# Slot          Description             Device(s)
U7879.001.DQD014E-P1-C3 PCI-X capable, 64 bit, 133MHz slot 0001:40:01.0 
```
If you are servicing a rack-mounted system, route the cables through the cable-management arm.
Replace or close the service access cover and, if applicable, return the system to the operating position. Refer to the following procedures as needed:
Verify that the new resource is functional. See Verify the installed part.
