Preparing the system to connect an EMX0 PCIe3 expansion drawer

To prepare the system to connect an EMX0 PCIe3 expansion drawer, complete the steps in this procedure.

About this task

Remember: Before you can connect a system to an EMX0 PCIe3 expansion drawer, your system must have the required number of PCIe3 cable adapters installed and the EMX0 PCIe3 expansion drawer must have the wanted number of PCIe3 6-slot fanout modules installed.

For instructions to install a PCIe3 cable adapter when you do not have an HMC, see PCIe adapters.
For instructions to install a PCIe3 6-slot fanout module when you do not have an HMC, see Installing the PCIe3 6-slot fanout module in the PCIe Gen3 I/O expansion drawer.
For instructions to install a PCIe3 cable adapter or PCIe3 6-slot fanout module when your system is managed by an HMC, see Installing a part by using the HMC.

Note: Before you attach your EMX0 PCIe3 expansion drawer to your system, ensure that you have the correct PCIe3 cable adapter and expansion drawer cables. Depending on the CCIN of the PCIe3 6-slot fanout module, use the following PCIe3 cable adapters and expansion drawer cables:

If you have a CCIN 50CB PCIe3 6-slot fanout module:
- You must install one of the following PCIe3 cable adapters:
  - FC EJ08 (CCIN 2CE2)
  - FC EJ07 (CCIN 6B52)
  - FC EJ05 (CCIN 2B1C)
- You must use one of the following expansion drawer cables: FC ECC6, FC ECC7, FC ECC8, FC ECC9, FC ECCR, FC ECCS, FC ECCX, FC ECCY, or FC ECCZ.
If you have a CCIN 50CD PCIe3 6-slot fanout module:
- You must install one of the following PCIe3 cable adapters:
  - FC EJ19 (CCIN 6B53)
  - FC EJ1R (CCIN 58FF)
  - FC EJ20 (CCIN 2CF5)
- You must use one of the following expansion drawer cables: FC ECCR, FC ECCS, FC ECCX, FC ECCY, or FC ECCZ.

Procedure

Determine the expansion drawer cable pair that can be used to connect the system to the EMX0 PCIe3 expansion drawer.
- Each cable pair must be the same length. You can verify the cable lengths by viewing the length labels that are on the plug ends or near the pull tabs on each cable.
- If your system and EMX0 PCIe3 expansion drawer are in the same rack and the system uses a cable management bracket, use the 2-meter cables.
- If your system and EMX0 PCIe3 expansion drawer are in the same rack and the system uses a cable management arm, use the 3-meter cables.
- If your system and EMX0 PCIe3 expansion drawer are in separate racks, use the 10-meter cables.
- If you have a 9080-M9S system and the EMX0 PCIe3 expansion drawer is in a separate rack, you might need to use the 20-meter cables.
If the system has a rear cover, remove or open it.
Carefully remove the expansion drawer cable pair from the packaging. Do not remove the protective covers now.
