Controller Boxes
To replace a Host I/O Board on CBXSS/CBXSL/CBSS/CBSL Controller Boxes:
1. Remove the host connector from the Host I/O Board to be removed.
2. Loosen the two blue screws that secure the Host I/O Board.
3. Pull out and remove the Host I/O Board.
4. Place the removed Host I/O Board and host connector in a temporary
location where anti-static measures are observed.
5. Wait at least 30 seconds, and then install the new Host I/O Board. If you
insert the Host I/O Board without waiting at least 30 seconds, the
controller might not recover normally. If this occurs, remove the inserted
Host I/O Board from the storage system, wait at least 30 seconds and
then re-insert it into the storage system.
6. Remove the host connector on the new Host I/O Board.
7. Insert and push the new Host I/O Board into the slot on the controller.
8. Push the levers at the same time in the direction shown by the arrows

12.Be sure the orange WARNING LED on the front side of the Controller
Box is OFF. If it blinks slowly, visit the HDS Support Portal at
The controller usually recovers in about three minutes;
however, if the I/O load from the host computer is high, it may take
about 30 minutes to recover.
13.Connect all the cables you removed.
14.Confirm that the green READY LED on the front of the Controller Box is
ON. This LED might blink quickly for 30-to-50 minutes before it goes ON.
If this LED blinks slowly, visit the HDS Support Portal at

replacing components (see
Checking recovery after replacing
NOTE: Although the red ALM LED might be ON when you insert the Host
I/O Board, it goes OFF after the controller recovers.
NOTE: When connecting Fibre Channel interface cables, insert the cables
until they are securely connected to the host connectors. If the Fibre
Channel interface cables are inserted half way into the host connectors, the
controller detects Fibre Channel failures and I/O processing can deteriorate
