Preparing the system to install a PCIe adapter in the EMX0 PCIe Gen3 I/O expansion drawer with the power turned on in AIX

Learn about steps you must complete before you install a PCIe adapter in the EMX0 PCIe3 expansion drawer.

1. Complete the prerequisite tasks. For instructions, see Before you begin.
2. Determine the slot in which you want to install a PCIe adapter. The PCIe adapter slots are located in the I/O module bay that is installed in rear of the EMX0 PCIe3 expansion drawer. Figure 1 shows the PCIe adapter location codes.

3. Use a console to access the PCI Hot Plug Manager.

   To access the PCI Hot Plug Manager, complete the following steps:

   1. Log in as root user.
   2. At the command line, type smitty.
   3. Select Devices.
   4. Select PCI Hot Plug Manager and press Enter.

      The PCI Hot-Plug Manager menu displays.

      For details about the menu options in the PCI Hot-Plug Manager screen, see PCI hot-plug manager menu.

4. From the PCI Hot-Plug Manager menu, select Add a PCI Hot-Plug Adapter, and then press Enter.

   The Add a Hot-Plug Adapter window displays.

5. Select the appropriate PCI slot from the ones listed on the screen, and then press Enter.
6. If applicable, open the rack door at the rear of the system.
7. Attach the electrostatic discharge (ESD) wrist strap. Your EMX0 PCIe3 expansion drawer has an ESD pin on the rear of the drawer. Attach the ESD wrist strap to the ESD pin on the rear of the drawer.
   Attention:

   • Attach an electrostatic discharge (ESD) wrist strap to the front ESD jack, to the rear ESD jack, or to an unpainted metal surface of your hardware to prevent the electrostatic discharge from damaging your hardware.
   • When you use an ESD wrist strap, follow all electrical safety procedures. An ESD wrist strap is used for static control. It does not increase or decrease your risk of receiving electric shock when using or working on electrical equipment.
   • If you do not have an ESD wrist strap, just prior to removing the product from ESD packaging and installing or replacing hardware, touch an unpainted metal surface of the system for a minimum of 5 seconds.

8. At the rear of the EMX0 PCIe3 expansion drawer, put the cable management bracket in the service position. See Figure 3.
   1. Pull out the quarter-turn fasteners (B) and turn them to disengage them while you lift the cable management bracket (A) to its raised position (1).
   2. Turn the quarter-turn fasteners (B) to engage and lock the bracket into position.
