Caution! Electrostatic discharge can severely damage sensitive electronic circuits. Before handling any electronic hardware, be sure to wear a grounding wrist strap or other static-dissipating device.


Caution! If a high or critical reliability system, replace and restore the disk drives one at a time starting with the standby SPE. Never replace the active and standby disk drives at the same time.

Type busyout host-adapter and press Enter. Make sure it says PASS.

For high or critical reliability

Type busyout host-adapter [a | b] and press Enter . Make sure it says PASS.

  2. Insert the new TN1657 circuit pack into the DISK DRIVE slot.

    3. To properly seat the circuit pack, push firmly on the front of the faceplate until the latch reaches the bottom rail of the carrier. Then close the latch until it is fully engaged.

  3. Allow the disk to spin up.

    3. After the second disk drive has been replaced, a minor alarm for DISK appears. This is because of the memory mismatch between the disk drive and the system.


Note: If you type the list configuration command before you've replaced both disks, the replaced disk drive will not show the correct vintage. The vintage table is not updated until you replace both disk drives.
