Replacing a PCI adapter contained in a cassette in the system with the power on in the Linux environment

You can replace a PCI adapter.

1. Complete the prerequisite tasks that are described in Before you begin.
2. Take appropriate precautions for avoiding electric shock and handling static-sensitive devices. For information, see Avoiding electric shock and Handling static-sensitive devices.
3. If the adapter needs to be placed in the PCI adapter cassette, see PCI adapter single-width and double-width cassettes.
4. At the back of the system, lift the cassette cover flap and identify the cassette slot you want to use.
5. Ensure the lower cassette handle is pressed up toward the retainer clip. This places the adapter in the correct position to be docked in the system.
6. Run the drmgr 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:

   drmgr -c pci -r -s locationcode

   Follow the instructions on the display to complete the task.

7. Remove the PCI adapter cassette from the system. Follow these substeps.
   1. Remove the PCI adapter EMC shield (A) as shown in Figure 1.
      Figure 1. Remove the EMC shield

      
   2. Slide the cassette (B) into the cassette slot as shown in Figure 2. When the cassette is fully inserted into the system, firmly press downward on the lower cassette handle (B) to lock the adapter in its connector.

   3. Replace the EMC shield (C) as shown in Figure 3.

8. 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
