Replacing an ATM3SA CRU

Installing an ATM3SA CRU

Note: Whenever you handle an ATM ServerNet adapter (ATM3SA) CRU, you

should follow standard operating practices to avoid damage to the equipment.

1 Put on the electrostatic discharge (ESD) wriststrap and attach the

grounding clip to the antistatic mat.

2 Place the package containing the ATM3SA CRU on the antistatic mat.

Caution: When opening the packing container, be careful not to cut

into the ESD protective bag.

Open the packing container and remove the ATM3SA CRU.

4 Disconnect the grounding clip of your ESD wriststrap from the antistatic

mat and connect it to an exposed, unpainted metal surface on the

ATM3SA CRU.

5 Grasp the ATM3SA CRU by its ejector in one hand, support the bottom

edge of the ATM3SA CRU with the other hand, and carry the ATM3SA

CRU to the service side of the system enclosure and set it down.

Note: The ATM3SA CRU weights 6.75 pounds (3 kilograms).

6 Disconnect the grounding clip of your ESD wriststrap from the ATM3SA

CRU and connect it to an exposed, unpainted, metal surface on the

service side of the system enclosure, such as the processor

multifunction (PMF) CRU or I/O multifunction (IOMF) CRU ventilation

holes.

The figure shows how to connect the grounding clip to the ventilation

holes on the PMF CRU or IOMF CRU .

7 With the ejector on the ATM3SA CRU in the full-open position, grasp the

ATM3SA CRU by the ejector with one hand and support the bottom edge

of the ATM3SA CRU with the other hand. Hold the ATM3SA CRU so that

its ejector is at the top and insert the ATM3SA CRU into the upper part of

the carrier.
