4. Remove power to the subsystem by turning off both AC input boxes for all
BA370 enclosures, and then disable the ECBs.
Caution: The ECB cable has a 12-volt and a 5-volt pin. Improper handling or
misalignment while connecting or disconnecting it can cause these pins to
contact ground, resulting in cache module damage.
5. Replace the ECB:
■ For a single ECB:
a. Remove the old ECB and insert the replacement ECB into the same
location.
b. Connect the replacement ECB to the open end of the ECB Y-cable
attached to the old ECB, and then quickly disconnect the Y-cable
from the old ECB.
■ For dual ECBs:
a. Connect the replacement ECB to the open end of the ECB Y-cable
attached to the old ECB, and then quickly disconnect the Y-cable
from the old ECB.
b. Place the replacement dual ECB in a temporary location.
6. Restore power to the subsystem.
The controllers automatically restart.
Note: A controller restart can take as long as 60 seconds, indicated by the temporary
cycling of the port LEDs and a flashing Reset button.
Note: If the controller did not restart, press the Reset button.
7. Set the controller time.
8. Start FRUTIL with the following command:
RUN FRUTIL
9. Enter Y(es) to confirm the intent to replace the “this controller” ECB with
power off.
