IBM EMX0 PCIe Gen3 Installing page 34

Procedure
1. Ensure that you have the electrostatic discharge (ESD) wrist strap on and that the ESD clip is plugged
into a ground jack or connected to an unpainted metal surface. If not, do so now.
2. Select from the following options:
• If you are working on a POWER9 processor-based 9080-M9S system or a POWER8 processor-
based 9080-MHE, 9080-MME, 9119-MHE, or 9119-MME system, you must label the cables.
Continue with step "3" on page 20.
• If you are not working on a POWER9 processor-based 9080-M9S system or a POWER8 processor-
based 9080-MHE, 9080-MME, 9119-MHE, or 9119-MME system, continue with step "10" on page
22.
3. Locate the following items that you need later in the procedure:
• Expansion drawer cable pairs
• Host system label sheet
• EMX0 PCIe3 expansion drawer label sheet
• Labeling diagram
4. Attach the host system location labels to the expansion drawer cable.
While you are completing these steps, refer to the following figure 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.
d) Determine the location of the PCIe3 cable adapter on the host system where you attach the first
expansion drawer cable pair.
e) Locate the labels on the host system label sheet (B) that correspond to the location of the PCIe3
cable adapter on the host system.
f) Select one of the expansion drawer cables as the top cable (D) that you will attach to port T1.
g) Attach the leftmost Cx-T1 label to the connector end of the cable (E).
Wrap the label with the blank end first so that the location information (F) is visible.
h) Take the second label Cx-T1 from the host system label sheet (B) and place it on the opposite end
of the cable that attaches to the EMX0 PCIe3 expansion drawer. Ensure that the label is placed
more than 100 mm (4 in) from the end of the cable (G).
i) Leave the cable near where it will be plugged.
j) Route the other end of the cable to the EMX0 PCIe3 expansion drawer to which it attaches.
k) Leave the cable near where it will be plugged.
