Replacing an E4SA CRU

Removing 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 Disconnect the communications cables from the E4SA CRU.
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) 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.
3 Unlatch the ejector on the E4SA CRU by pressing the blue-green tab on the ejector and
pulling the ejector outward to unseat the E4SA CRU from the backplane.
4 Grasp the E4SA CRU by its ejector with one hand and slowly pull the E4SA CRU out of the
slot while supporting the bottom edge of the E4SA CRU with the other hand.
Note: The E4SA CRU weighs 6.75 pounds (3 kilograms).
The figure shows how to pull the E4SA CRU out of the slot.
5 Place the E4SA CRU in the ESD protective bag and return it to its original packing container.
