Remove the Adapter

The following steps describe how to remove the adapter:

1. Disconnect the communications cables from the TRSA.

2. Put on your electrostatic discharge (ESD) wriststrap and connect the grounding clip

securely to an exposed, unpainted, metal surface on the service side of the system

enclosure, such as the processor multifunction (PMF) adapter or I/O multifunction

(IOMF) adapter ventilation holes

Figure 3-4

on page 3-17 shows how to connect the grounding clip to the ventilation

holes on the PMF adapter or IOMF adapter.

3. Unlatch the ejector on the TRSA by pressing the blue-green tab on the ejector and

pulling the ejector outward to unseat the TRSA from the backplane.

4. Grasp the TRSA by its ejector in one hand and slowly pull the TRSA out of the slot

while supporting the bottom edge of the TRSA with the other hand.

Figure 3-5

shows how to pull the adapter out of the slot.
