Replacing the Disk I/O Card

NOTE:
The Disk I/O Card is hot-swappable.
1 Locate and verify which is the faulty Disk I/O card.

Remove the Fibre Channel data cables from the transceiver(s) that are to be
removed. Insert the dust covers on the data cable connector(s). This will
protect the optics.
3 Each transceiver model has a slightly different mechanism for ejection. Refer
to the illustration below and note the model you have.
4
Using the ejector, release the transceiver and pull it from the SFP cage.
a The type A model uses a pivoting mechanism. Use the edge of your
finger tip or the finger nail to engage the ejector and pull towards you.
This will release the transceiver.
b The type B model uses a similar mechanism to the type A except it
rotates about a pivot point. Use the edge of your finger tip or the finger
nail to engage the ejector and pull towards you. This will release the
transceiver.

the tab to release the transceiver.
