Replacing a TRSA CRU

Removing a TRSA CRU
Note: Whenever you handle a Token-Ring ServerNet adapter (TRSA) CRU, you should follow
standard operating practices to avoid damage to the equipment.
1 Disconnect the communications cable from the TRSA CRU to be removed
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 TRSA CRU by pressing the blue-green tab on the ejector and
pulling the ejector outward to unseat the TRSA CRU from the backplane.
4 Grasp the TRSA CRU by its ejector with one hand and slowly pull the TRSA CRU out of the
slot while supporting the bottom edge of the TRSA CRU with the other hand.
Note: The TRSA CRU weighs 6.75 pounds (3 kilograms).
The figure shows how to pull the TRSA CRU out of the slot.
5 Place the TRSA CRU in the ESD protective bag and return it to its original packing
container.
