Using the Isolator/Repeater Board
Carrier Removal
Follow the procedures below to remove the DE100 carrier from the receiving frame equipped
with the Isolator/Repeater Board.
1. Verify that the drive is not active. If the system is on a network, make certain other users
are not accessing the target drive, then disable it from the network. Dismount the drive.
2. Turn the DE100 key lock mechanism (located on the front of the receiving frame),
clockwise to the OFF position. This unlocks the drive from the receiving frame and
activates the Isolator Board. The unit ID number on the display will begin flashing.
WARNING: Be careful not to remove or disturb the carrier unit at this point. Although
the carrier is physically unlocked, the drive requires a minimum of 15
seconds to spin down and is subject to vibration and possible damage
during this period.
3. As the unit ID number flashes, the board monitors the activity of the SCSI bus. When
activity is no longer present, the board will remove power from the drive and then
remove the device from the SCSI Bus. The unit ID number will continue to flash during
this period.
4. After a short length of time the unit display will turn from a flashing unit ID number to
a steady “u”, indicating that the device is powered down, unlocked and ready to be
removed from the receiving frame.
Carrier Installation
Follow the procedures below to install the DE100 carrier into the receiving frame equipped with
the Isolator/Repeater Board.
1. Install the carrier into the receiving frame. A "u" will be present on the front panel.
2. Turn the key lock mechanism, located on the front of the receiving frame, counterclock-
wise to the ON position. This locks the drive into the receiving frame and activates the
Isolator Board. The drive will begin to spin up and the unit ID number on the display will
begin flashing.
3. After a short length of time the unit ID display will stop flashing, indicating that the device
is ready to be used.
NOTE: No onboard termination is provided on the S20A102. External termination must
be provided.
