5. Set the SCSI drive tray in a safe and secure area.
Caution -
![](12-Slot.fig.15.gif)
Circuit board components can be damaged by electrostatic discharge
(ESD). An electrostatic charge can build up on the human body and then
discharge when you touch a board or a magnetic storage device, such as a tape
drive. Such discharge can be produced by walking across a carpet and
touching a board, or by any other similar action. Before handling any board or
magnetic storage device, make sure you dissipate your body's charge by
following these instructions carefully.
Follow these instructions to unpack and inspect the drive:
1. Unpack the 5.0 Gbyte 8 mm tape drive.
2. Place the tape drive on top of the bag it was shipped in.
Placing the drive on the bag will prevent static discharge from accumulating
in the device.
3. Inspect the tape drive for evidence of damage.
If damaged, keep all contents and packing materials for the carrier's agent
to inspect.
4. Verify that the shipping container has all the contents you will need to
install the 5.0 Gbyte 8 mm tape drive.
The shipping container should have the following items:
-
one 5.0 Gbyte 8 mm tape drive
-
four manuals, including this one
5. Save packing materials for future use.
Follow these instructions to set the SCSI address on your 5.0 Gbyte 8 mm tape
drive:
1. Determine if there are any jumpers installed on the SCSI ID connector at
the rear of the tape drive (see Figure 2-5 for the location of the SCSI ID
connector).
A jumper is a small sleeve that slides over two adjacent pins in the SCSI ID
connector to provide an electrical connection. If there are jumpers installed
on the SCSI ID connector, remove the jumpers using the needle-nosed pliers.
