Replacing an E4SA CRU

Installing an E4SA CRU

Note: Whenever you handle an Ethernet 4 ServerNet adapter (E4SA) 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 E4SA 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 E4SA 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 E4SA

CRU.

5 Grasp the E4SA CRU by its ejector in one hand, support the bottom

edge of the E4SA CRU with the other hand, and carry the E4SA CRU to

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

Note: The E4SA CRU weights 6.75 pounds (3 kilograms).

6 Disconnect the grounding clip of your ESD wriststrap from the E4SA

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 E4SA CRU in the full-open position, grasp the

E4SA CRU by its ejector with one hand and support the bottom edge of

the E4SA CRU with the other hand. Hold the E4SA CRU so that its

ejector is at the top and insert the E4SA CRU into the upper part of the

carrier.
