Learn how to replace the Peripheral Component Interconnect (PCI) Express (PCIe)
adapters in a Linux system or
a Linux logical partition with the system power turned
on.
To
complete this procedure, you must have removed a PCIe adapter from the system. For instructions,
see 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.
To replace a PCIe adapter in the system, complete
the following steps:
- 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.
- Ensure that the target slot is empty.
- 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, antistatic surface.
Note: Some PCIe adapters are
shipped from the manufacturer with a blue handle or support bracket
along the back edge of the adapter. To use adapters of this type,
you must remove the blue handle or the support bracket from the adapter.
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.
- Enter drmgr on
the console to enable an adapter to be replaced.
For
example, to replace the PCIe adapter in slot U7879.001.DQD014E-P1-C3
enter: drmgr -c pci -r -s locationcode
Follow
the instructions on the display to complete the task.
- Return to the system.
- If the adapter latch (B) at
the target slot is not already in the open position, pull the latch
into the open position by rotating the latch outwards from its clip
on the back of the system, as shown in Figure 1.
Attention: Before you insert the adapter in the PCIe
slot, ensure that the adapter has no cables, protective shields, or transceivers that are attached
to it. If the adapter has cables, protective shields, or transceivers that are attached, remove
them.
For instructions to remove protective shields or transceivers, see
Removing and replacing the tailstock on a PCIe adapter. The cables, protective shields, or transceivers must
be attached to the adapter after the adapter is inserted in the PCIe slot.
- Carefully
grasp the adapter by its top edge or tailstock, and align the adapter with the slot and its
connector on the system backplane (A), as shown in Figure 1.
- On the system, press the adapter firmly into its connector.
- To lock the adapter in
its slot, rotate the adapter latch (B) in the
direction that is shown in Figure 1.

8247-21L, 8247-22L, 8284-21A, or 8284-22A system
- If you replaced the PCIe adapter as part of another service
procedure, return to that procedure.
