IBM EMX0 PCIe3 Installing page 38

Remember: Before you can connect a system to an EMX0 PCIe3 expansion drawer, the 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.
v For instructions about installing a PCIe3 cable adapter, see PCIe adapters (http://www.ibm.com/
support/knowledgecenter/POWER8/p8hak/pciadapters.htm).
v For instructions about installing a PCIe3 6-slot fanout module, see Installing the PCIe3 6-slot fanout
module in the PCIe Gen3 I/O expansion drawer (http://www.ibm.com/support/knowledgecenter/
POWER8/p8egv/p8egv_emx0_kickoff_install.htm).
Important: To avoid damage to the connectors on the expansion drawer cables, do not remove the
protective covers until just before you need to plug the cable into the host system or the EMX0 PCIe3
expansion drawer.
To connect the EMX0 PCIe3 expansion drawer to a system, complete the following steps:
1. Determine the expansion drawer cable pair that can be used to connect the system to the EMX0
PCIe3 expansion drawer.
Notes:
v 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.
v 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.
v 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.
v If your system and EMX0 PCIe3 expansion drawer are in separate racks, use the 10-meter cables.
v If you have a 9080-MHE, 9080-MME, 9119-MHE, or 9119-MME system and the EMX0 PCIe3
expansion drawer is in a separate rack, you might need to use the 20-meter cables.
2. If the system is not already powered off, turn off the system. For instructions, see "Stopping a
system or logical partition" on page 31.
3. If the system has a rear cover, remove or open it.
4. Ensure that you have the electrostatic discharge (ESD) wrist strap attached. If not, attach it now.
5. Carefully remove the expansion drawer cable from the packaging. Do not remove the protective
covers now.
6. Select from the following options:
v If you are connecting the EMX0 PCIe3 expansion drawer to a 9080-MHE, 9080-MME, 9119-MHE,
or 9119-MME system, you will need to label the cables. Continue with step 7.
v If you are not connecting the EMX0 PCIe3 expansion drawer to a 9080-MHE, 9080-MME,
9119-MHE, or 9119-MME system, continue with step 14 on page 24.
7. Locate the following items that you need later in the procedure:
v Expansion drawer cable pairs
v Host system label sheet
v EMX0 PCIe3 expansion drawer label sheet
v Optional: Labeling diagram
8. Attach the host system location labels to the expansion drawer cable.
Note: While you are completing these steps, refer to Figure 17 on page 23 as a reference.
a. Locate the host system (A) that you are attaching to the EMX0 PCIe3 expansion drawer.
b. Locate the host system serial number label sheet (B).
c. Match the host system serial number (C) to the serial number shown on the host system label
sheet.
