ATTENTION Possible equipment damage – When you remove the host interface
card, be careful not to disconnect the seven-segment display from the sheet metal
cover. If you need to remove the sheet metal cover, you must first remove the
seven-segment display ribbon cable from the motherboard connector. To disconnect
the seven-segment display from the motherboard connector, you must lift the center
piece of the motherboard connector, and remove the ribbon cable.
16. Locate the host interface card that you want to replace.
17. Loosen the thumbscrew on the host interface card that secures it to the controller
card.
18. Gently lift the host interface card to disengage the pins from the connector on the
controller card, and remove the host interface card from the controller canister.
NOTE The connector is located on the corner of the host interface card next to the
thumbscrew. Note how the card fits against the two guide posts. These guide posts help
to make sure that the connecting hardware is aligned.
19. Place the host interface card that you removed on a flat, static-free surface.
NOTE Make sure that you have the correct host interface cards (HICs), Small
Form-factor Pluggable (SFP) transceivers, and host bus adapters. If you are replacing
one HIC with a different type of HIC, you might not be able to reuse the SFP
transceivers. Use only the correct SFP transceiver for the interface type and speed of
your HIC.
1. Install the new HIC.
a. Align the new HIC with the guide posts.
b. Gently push down on the HIC to seat the pins into the connector on the
controller card.
2. Tighten the thumbscrew on the HIC to make sure that it is securely fastened to
the controller card.
NOTE Make sure that the seven-segment display ribbon cable is still connected to the
motherboard connector. If the ribbon cable is not connected, you must lift the center
piece of the motherboard connector, and insert the ribbon cable into the motherboard
connector.
3. Replace the faceplate, and tighten the thumbscrew that secures it to the controller
tray.
NOTE Make sure that the faceplate has the correct overlay, so that the information on
the front of the faceplate corresponds with the HIC.
