DE100/DE200 Ultra2 (LVD) Hot Swap/Repeater Isolator Board
D89-0000-0087 Rev. B00 StorCase Technology, Inc.
Using the Isolator Board
Carrier Removal
Follow the procedures below to remove the Data Express carrier from the receiving frame
equipped with the isolator 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/DE200 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 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 Data Express carrier into the receiving frame e-
quipped with the isolator board.
1. Install the carrier into the receiving frame. A "u" will be present on the front panel, in-
dicating that the carrier is in an unlocked condition.
2. Turn the key lock mechanism, located on the front of the receiving frame, counter-
clockwise to the ON position. This locks the drive into the receiving frame and activates
the 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 de-
vice is ready to be used.
NOTE: No onboard termination is provided on the DE100/DE200. External termi-
nation must be provided.
