Procedure
Step 1. Make preparation for this task.
a. Remove the server cover. See “Remove the server cover” on page 135.
Attention: The heat sink and processor could be very hot. To avoid burning yourself, wait for a
few minutes after turning off the server before you remove the server cover.
b. Disconnect all PCIe adapter cables. See
Chapter 6 “Internal cable routing” on page 145.
Step 2. Remove the PCIe adapter.
a.
Rotate the PCIe adapter retainer clip to the open position.
b.
Press the retaining clip to release the PCIe adapter.
Note: This step is applicable only to the PCIe adapter installed in PCIe slot 1.
c.
Hold the PCIe adapter by both edges, and gently lift it out from the PCIe slot.
Note: The PCIe adapter might be clamped by the slot tightly. In this case, gently and evenly
shake the PCIe adapter until the clamping force from the connector is significantly reduced
and the adapter becomes easily removable.
