Figure 5. Removing a tailstock filler from the cassette for the 9040-MR9 system
Note: Your cassette might not have the two adapter retainers (C) and strips.
d) Save the tailstock filler for a future use.
You must have a tailstock filler in an empty PCIe cassette in a system to ensure proper airflow.
6. Choose from the following options:
• To install a PCIe adapter into a cassette that has adapter retainers and strips, continue with step
"7" on page 10.
• To install a PCIe adapter into a cassette that doesn't have adapter retainers and strips, continue
with step 8.
7. If your cassette has two adapter retainers with strips, complete the following steps to install or
replace a PCIe adapter into the cassette:
a) If the adapter retainers (A) haven't already been removed, remove the adapter retainers (A) by
putting them in the open position and moving them all the way off the strips.
