Regulatory Compliance Notices
Federal Communications
Commission Notice
Part 15 of the Federal Communications Commission (FCC) Rules and
Regulations has established Radio Frequency (RF) emission limits to provide
an interference-free radio frequency spectrum. Many electronic devices,
including computers, generate RF energy incidental to their intended function
and are, therefore, covered by these rules. These rules place computers and
related peripheral devices into two classes, A and B, depending upon their
intended installation. Class A devices are those that may reasonably be
expected to be installed in a business or commercial environment. Class B
devices are those that may reasonably be expected to be installed in a
residential environment (i.e., personal computers). The FCC requires devices
in both classes to bear a label indicating the interference potential of the device
as well as additional operating instructions for the user.
The rating label on the device shows which class (A or B) the equipment falls
into. Class B devices have an FCC logo or FCC ID on the label. Class A
devices do not have an FCC logo or ID on the label. Once the class of the
device is determined, refer to the following corresponding statement.

other static-sensitive devices. This type of damage may reduce the life
expectancy of the device.
To prevent electrostatic damage, observe the following precautions:
■
■
■
Avoid hand contact by transporting and storing products in static-safe
containers.
Keep electrostatic-sensitive parts in their containers until they arrive at
static-free workstations.
Place parts on a grounded surface before removing them from their
containers.
■
■
Avoid touching pins, leads, or circuitry.
Always be properly grounded when touching a static-sensitive
component or assembly.
Grounding Methods
There are several methods for grounding. Use one or more of the following
methods when handling or installing electrostatic-sensitive parts:
■
Use a wrist strap connected by a ground cord to a grounded workstation
or computer chassis. Wrist straps are flexible straps with a minimum of
1 megohm 10 percent resistance in the ground cords. To provide
proper ground, wear the strap snug against the skin.
■
■
Use heel straps, toe straps, or boot straps at standing workstations.
Wear the straps on both feet when standing on conductive floors or
dissipating floor mats.
Use conductive field service tools.

■
Use a portable field service kit with a folding static-dissipating
work mat.
If you do not have any of the suggested equipment for proper grounding, have
an Authorized Compaq Reseller install the part.
NOTE: For more information on static electricity, or assistance with product
installation, contact your Authorized Compaq Reseller.

C-1 Drive Configuration Options
Appendix C
Drive Configuration Options
Your Compaq SLR SLR Drive has been configured by Compaq to meet the
requirements of the typical user. This chapter contains information on
changing the default configuration.
Most of the drive’s options are controlled internally. However, the user has
access to certain options via the jumper block located at the rear of the drive.
The options available to the user are:
■
■
■
Selecting the SCSI ID
Enabling/Disabling bus parity
Testing
Locating the Jumper Block
Locate the jumper block at the rear of the drive.

C-3 Drive Configuration Options
Selecting the SCSI ID
Since each device on the same SCSI bus must have a unique ID, the user may
need to set the drive’s ID before installation.
IMPORTANT: The drive has been configured by Compaq with SCSI ID = 6 selected. Do
not use SCSI ID = 7: this is reserved for SCSI controllers
Use the following table to obtain the appropriate jumper settings:

In the above table, “CLOSED” indicates that a jumper has been installed.
NOTE:
IMPORTANT: The drive reads the jumper block settings at power-on. For changes to
be effective, either the user must turn the drive OFF then back ON or the drive must
receive a SCSI Bus Reset.

C-4 Drive Configuration Options
Configuring the SCSI ID in a
SCO OpenServer environment
In the pre-configured kernel used to install SCO OpenServer, the following
SCSI IDs are automatically set:
■
■
■
Disk = 0
Tape = 2
CD-ROM = 5.
If required, the user may reconfigure the ID for the Compaq SLR Drive using
the mkdev tape command. To verify the ID, use the hwconfig command look
for the same %tape string or check the %tape string as it appears on the
console as the kernel starts up. The information will appear in a line such as
this:
%tape - - - type= S ha=0 id=2 lun=0 ht= ...
In the above example, “id=2” indicates that the drive’s SCSI ID = 2.
IMPORTANT: SCO OpenServer’s install kernel will only communicate with the first
SCSI controller in the system. Remove the generic tape at SCSI ID = 2 then install the
appropriate tape driver. Set the required SCSI ID, bus, and lun values.
Enabling/Disabling Bus Parity
Installing the PARITY jumper enables bus parity checking.
IMPORTANT: Compaq ships the drive with this jumper installed.
Testing
The TEST and TEST CONN jumpers enable selftest and off-line testing
capabilities which are beyond the scope of this guide.
