8.4.6 Swapping EEPROM between Controllers
The following procedure describes removing the EEPROM from a defective
RAID controller and inserting it into a new RAID controller. This procedure is
used in the event that the existing configuration cannot be saved to a diskette.
CAUTIONS
To avoid static damage, follow adequate anti-
static procedures when handling the RAID control-
ler. For example, use the following procedure in a
static protected area and be sure to use a static
strap.
Take care not to bend the pins on the EEPROM.
The pins must be perfectly aligned with the con-
nector on the board before any insertion pressure
is applied to the EEPROM.
To remove the EEPROM from the controller, follow these steps.
1. Turn off the system.
2. Turn off the storage pedestal(s).
3. Disconnect the cable(s) connecting the controller to the storage pedestal(s).
Label cable(s) for future identification.
4. Remove the defective controller.
5. Make note of EISA slot where the board was located.
6. Carefully remove the EEPROM at U33 (Figure 8–5) from the new control-
ler. Label EEPROM as "new" and set it aside carefully.
7. Carefully remove EEPROM at U33 from the defective controller and set
controller aside (out of the way).
8. Carefully align the notches of the old EEPROM with the notch at connector
U33 on the new RAID board to ensure that pin 1 is aligned correctly. Care-
fully insert the old EEPROM into position U33.
9. Install the new RAID board with the old EEPROM into the same EISA slot
that the old RAID Board was in. Connect the previously labeled cable(s) to
the correct storage pedestal connector(s), and power on the pedestal(s).
