Removing a PCIe adapter from the 8408-44E or 8408-E8E system with the power turned on in Linux

To remove the Peripheral Component Interconnect (PCI) Express (PCIe) adapters from a Linux system or a Linux logical partition with the system power turned on, complete the steps in this procedure.

1. Ensure that you have the electrostatic discharge (ESD) wrist strap attached. If not, attach it now.
2. Remove the PCIe adapter.
   Attention:

   • Left and right I/O retention brackets must be opened before you can access the rear slots.
   • You only need to open the I/O retention bracket for the side you are accessing.
   • A pin on the tailstock of the adapter resembles a removable screw. Do not remove this pin. It is required for correct alignment and seating.
   1. Unscrew the I/O retention bracket captive thumbscrew until fully loose. See (A) in Figure 1.
   2. Open the I/O retention bracket by rotating it up and away from the system. See (B) in Figure 1.
   3. Carefully grasp the adapter (C) by its top edge or tailstock, and remove adapter from the slot, as shown in Figure 1.
      Note: If you are removing a low-profile (short) PCIe adapter, disengage the adapter by pushing in the tailstock while you are lifting the adapter out of the slot.

3. Place the removed adapter on an approved ESD surface.
4. Choose your next action from the following options:
   • If you are removing a PCIe adapter as part of another procedure, return to that procedure.
   • If you are replacing the failed adapter with a new adapter, go to the procedure for replacing a PCIe adapter.
   • If you are not replacing the PCIe adapter with a new one, you must install a PCIe tailstock filler in the empty slot. To install a PCIe tailstock filler, complete the following steps:
     1. Carefully grasp the filler tailstock and align the filler with the slot and its connector on the system backplane, see (A) in Figure 2.
     2. Press the filler tailstock firmly into the slot.
     3. Close the I/O retention bracket by rotating it down towards the system (B). See Figure 2.
     4. Screw the I/O retention bracket captive thumbscrew clockwise (C), as shown in Figure 2.
