Remove and Install the Adapter
6. Disconnect the grounding clip of your ESD wriststrap from the TRSA and connect it
to an exposed, unpainted, metal surface on the service side of the system enclosure,
such as the ventilation holes on the processor multifunction (PMF) adapter or I/O
multifunction (IOMF) CRU.
Figure 4-4
on page 4-18 shows how to connect the grounding clip to the ventilation
holes on the PMF or IOMF CRU.
7. With the ejector on the TRSA in the full-open position (Figure 4-6
), grasp the TRSA
by the ejector with one hand and support the bottom edge of the TRSA with the
other hand (Figure 4-7 on page 4-21). Hold the adapter so that its ejector is at the
top, as shown in Figure 4-6
, and insert the adapter into the upper part of the carrier.
8. Push the TRSA to the rear of the slot, but don't force it.

Caution. Apply equal pressure to both the top and bottom of the TRSA when pushing it into
the slot to avoid damaging the connector pins. If pins are damaged, both the TRSA and the
backplane (or enclosure) must be replaced.
