9. Remove the screws holding the front bezel to the controller canister with a
phillips screwdriver.
NOTE The front bezel can suddenly pop loose and cause damage to either the front
bezel flex harness or the zero insertion force (ZIF) socket that is attached to the
controller card. Make sure that you gently move the front bezel away from the
controller canister to allow access to the HIC.
10. Remove the front bezel from the controller canister, carefully working it from
side-to-side until you can slide it off and gain access to the HIC.
11. Loosen the HIC thumbscrews that secure the HIC to the controller card.
NOTE If the thumbscrews were overtightened, you may use a phillips screwdriver to
help you loosen them.
12. Gently disengage the HIC from the controller card, and remove the HIC.
NOTE The connector is located on the edge of the HIC next to the thumbscrews.
13. If you are changing the HIC type, remove the HIC subplate from the front bezel.
14. Place the HIC that you removed on a static-free surface.
15. Go to "Removing the Controller Canisters from the E5460 Controller-Drive
Tray" on page 99.
Installing the Host
Interface Card in the
E5400 Controller-Drive
Tray
NOTE Make sure that you have the correct host interface card (HIC), Small
Form-factor Pluggable (SFP) transceivers, and host bus adapters or host channel
adapters. Because you are replacing one HIC with a potentially different type of HIC,
you might not be able to reuse the SFP transceivers. For more information, refer to the
Hardware Cabling Guide.
1. Install the new HIC by gently connecting the HIC to the HIC interface connector.
Do not scratch or bump any of the components on the bottom of the HIC or the
top of the controller card.
ATTENTION Potential loss of connectivity – If both controllers in a duplex
controller-drive tray are powered up at the same time with different types of HICs, a
mismatch results that causes both controllers to lock down (shut down and stop
operating). If one controller is already running, and you replace the alternate controller
with a different HIC, then only the replacement controller locks down, and the running
controller remains operational.
2. Install and tighten the HIC thumbscrews that secure the HIC to the controller
card.
