Removing a PCIe adapter from the 5148-21L, 5148-22L, 8247-21L, 8247-22L, 8284-21A, or 8284-22A system with the power turned on in Linux

Learn how 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.

1. Ensure that you have the electrostatic discharge (ESD) wrist strap on and that the ESD clip is connected to an unpainted metal surface. If not, do so now.
2. To set the adapter latch (A) at the target slot into the open position, rotate the latch (A) on the rear of the system, in the direction shown in Figure 1.
3. Carefully grasp the adapter (B) by its top edge or tailstock, and remove the adapter from the slot, as shown in Figure 1.
   Attention: 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.

4. Place the removed adapter on an approved ESD surface.
5. 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 one, go to the procedure for replacing a PCIe adapter.
   • If you are not replacing with a new adapter, 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, as shown in Figure 2.
     2. Press the filler tailstock firmly into the slot.
