DMS-100 Family NA100 Trouble Locating and Clearing Procedures Volume 2 of 2 LET0015 and up
Trouble locating and clearing procedures (continued)
DANGER
Loss of data
Do not twist the ribbon cable. Failure to route the ribbon
cable correctly can result in signal interference, which can
cause a loss of data.
To reconnect the ribbon cable, hold the connector in place and snap the
retainer clips into place. Refer to the diagram in step 18.
Connect the power cable into the back of the DDU.
Go to step 47.
Disconnect the power cable from the back of the DDU.
WARNING
Equipment damage
The retaining clips hold the ribbon cable in place, and the
cable disconnects when the clips release. Do not pull on the
cable to disconnect it because you might rip the connector
socket away from the disk drive unit.
To disconnect the DDU end of the ribbon cable, release the retaining clips to
unplug the connector.
Carefully slide the DDU out of the frame. Slide the DDU until the spring clips
on the sides of sliders cause the DDU to stop.
Remove the four screws that mount the DDU to the two mounting brackets on
the drawer.
