Replacing the Host I/O Card
WARNING: The Host I/O card is NOT HOT SWAPPABLE. You must POWER
DOWN the storage system to replace this card.
1 Power down the storage enclosure, refer to “Powering Off the Storage
System” on page 70.
2 Identify the faulty Host I/O card. Refer to “Troubleshooting” on page 107 for
information on identifying the card.
3 Remove the Fibre Channel data cables from the transceiver(s). Insert the dust
covers on the data cable connector(s). This will protect the optics.
4 Using the ejector, release the transceiver and pull it from the SFP cage.
Each transceiver model has a slightly different mechanism for ejection. Refer
to the illustration below and note the model you have.
a The “A” model uses a pivoting mechanism. Use the edge of your finger
tip or finger nail to engage the ejector and pull towards you. This will
release the transceiver.

b The “B” model uses a similar mechanism to the “A” model except it
rotates about a pivot point. Use the edge of your finger tip or finger nail to
engage the ejector and pull towards you. This will release the transceiver.
