Step Action
1 Turn off power using the switch on the node power
supply.
2 Disconnect the item connected to J1 on the HDDT I/
O board. This is the SCSI interface cable to the
optional DAT/CD-ROM devices if they exist. It is a
terminator assembly if the optional devices do not
exist.
3 Remove the board by removing the two screws that
secure the face plate to the chassis. Non-CE
compliant HDDT I/O boards have extraction/insertion
levers instead of screws.
4 Insert the replacement board. Make sure it is properly
seated.
5 Reconnect the cable (or terminator assembly) onto
J1 of the new HDDT I/O board. This item was
removed in step 2.

the power switch located on the A
