Replacing the Controller (and Swapping the EEPROM)
The following procedure describes swapping the EEPROM from a defective SWXCR
controller to a new SWXCR controller. Use this procedure in the event that you cannot save
the existing configuration to a diskette.
______________________CAUTION ___________________________
To avoid static damage, follow adequate antistatic procedures when handling the
RAID controller. For example, use the following procedure in a static protected
area and be sure to use a static strap.
To remove the EEPROM from the controller, follow these steps.

"new" and set it aside carefully.
3
Carefully remove EEPROM at U33 from the defective controller and set it
aside (out of the way).
4
Take the new board and align the notches of the old EEPROM with the
notch at U33 on the new controller to ensure that pin 1 is aligned correctly.
Carefully insert the old EEPROM into position U33.
WARNING: Do not bend the pins on the EEPROM.
