handling or misalignment when connecting or disconnecting
could cause these pins to contact ground, resulting in cache
module damage.
6. Connect the open end of the ECB Y cable to the new ECB.
7. Restore power to the subsystem. The array controller automatically restarts.
8. Disconnect the ECB cable from the old ECB.
