Figure B-2: Hot Swap Board Termination Jumpers

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.

As the unit number flashes, the Hot Swap Board monitors the activity of the SCSI bus.
When activity is no longer present, the Hot Swap Board will remove power from the
drive and then remove the device from the SCSI Bus. The unit number will continue to
flash during this period.

After a short length of time the unit display will turn from a flashing unit number to a
steady “u”, indicating that the device is powered down, unlocked and ready to be
removed from the receiving frame.
