Installing an EMX0 PCIe Gen3 I/O expansion drawer
Learn how to install an EMX0 PCIe Gen3 I/O expansion drawer (EMX0 PCIe3 expansion drawer) into a
rack or remove the shipping bracket from a preinstalled EMX0 PCIe3 expansion drawer. Then, learn how
to connect the EMX0 PCIe3 expansion drawer to your system and activate the PCIe link.
Notes:
• If you have a POWER9 processor-based 9080-M9S system and it is being installed at the same time as
your EMX0 PCIe3 expansion drawer, the service provider completes the installation of the EMX0 PCIe3
expansion drawer. If you already have the 9080-M9S system that is installed, and you ordered an EMX0
PCIe3 expansion drawer, the installation and setup of the EMX0 PCIe3 expansion drawer is a customer
task. You can complete this task yourself, or contact a service provider to complete the task for a fee.
• If you have a POWER8
it is being installed at the same time as your EMX0 PCIe3 expansion drawer, the service provider
completes the installation of the EMX0 PCIe3 expansion drawer. If you already have the 9080-MHE,
9080-MME, 9119-MHE, or 9119-MME system that is installed, and you ordered an EMX0 PCIe3
expansion drawer, the installation and setup of the EMX0 PCIe3 expansion drawer is a customer task.
You can complete this task yourself, or contact a service provider to complete the task for you for a fee.
• If you have any other type of system, the installation and setup of the EMX0 PCIe3 expansion drawer is
a customer task. You can complete this task yourself, or contact a service provider to complete the task
for you for a fee.
Installing or setting up an EMX0 PCIe3 expansion drawer
Learn how to install an EMX0 PCIe3 expansion drawer into a rack or set up a preinstalled EMX0 PCIe3
expansion drawer.
Complete the following tasks to install or set up an EMX0 PCIe3 expansion drawer:
1. Preparing to install or set up an EMX0 PCIe3 expansion drawer
2. Completing inventory for the EMX0 PCIe3 expansion drawer
3. Determining and marking the location in the rack
4. Attaching the mounting hardware to the rack
5. Installing the EMX0 PCIe3 expansion drawer into the rack
Preparing the system to install or set up an EMX0 PCIe3 expansion drawer
Find information about the prerequisites for installing your EMX0 PCIe3 expansion drawer.
About this task
Important: Changing the cable configuration of an existing EMX0 PCIe3 expansion drawer or drawers can
result in unintended I/O configuration changes, including a change to the bus numbers assigned to
existing expansion drawers. When bus numbers change, partition profiles cannot find existing I/O
resources.
To prepare the system to install an EMX0 PCIe3 expansion drawer, complete the following steps:
Procedure
1. Ensure that a PCIe3 cable adapter is installed in the host system before you install the EMX0 PCIe3
expansion drawer.
If you are working on a POWER9 processor-based system: For all systems except the 9040-MR9 or
9080-M9S, you must power off the system to install the PCIe3 cable adapter.
