Removing Hot-Swap Drives

CAUTION
You must slowly remove the drive to ensure that the drive heads
are parked prior to removal. Be sure to follow these instructions
carefully to prevent damage such as head slaps or head actuator
unlocking.
1. To unlock the drive, push in the locking latch, and then pull the ejector
handle toward you.
2. Gently pull out the drive about an inch to disengage the power connection.
3. Wait about 30 seconds for the drive to stop spinning and for the drive
heads to park.
4. Using your hand to support the bottom of the drive, slowly pull out the
drive in a straight and forward direction. Do not let the drive fall.
5. Place the drive in an electrostatic protected container. Do not stack drives.
6. Use a filler panel to cover the space created by the removal of the drive.
See the "Removing a Filler Panel" section for instructions.
NOTE
Leave the filler panels in place unless you are installing a SCSI
device. They are required for proper ventilation.

Connecting SCSI Subsystems

The external SCSI connector, Channel B, is used for connecting external SCSI
subsystems, such as the HP Rack Storage/12.
CAUTION Do not mix high-voltage differential (HVD) drives and
receiver devices with the SE, LVD (Ultra 2), or multimode
devices on the same SCSI channel.
