Figure B-1: Attaching the Hot Swap Board
Jumper Options
Most jumper options are configurable via the receiving frame motherboard (Figures 5 & 8).
The Hot Swap Board provides three configurable jumpers, DTA, DTB, and DTC (Figure B-2).
When installed (factory default), these jumpers disable onboard termination at drives A, B, and
C, respectively. If a DE300 drive will be physically located at the end of a SCSI daisy chain,
remove the appropriate jumper to enable termination.
Using the Hot Swap Board
Carrier Removal
Follow the procedures below to remove the Data Express carrier from the receiving frame
equipped with the Hot Swap option.
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 DE300 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 Hot Swap 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.
