SCSI IDs and Expansion Boxes
Digital first introduced the VAXstation 3100 family of products .
in January 1989. Since that tim~ changes to existing Small
Computer System Interface (SCSI) products and the introduction
of new SCSI products have prompted questions from customers
about SCSI. For example, customers ask; How many expansion
boxes and SCSI devices may be connected to a VAXstation 3100?

SCSI Configuration Rules
The draft ANSI SCSI-2 specification (Revision lOb) provides up to
8 SCSI IDs (addresses). One of the 8 addresses is always used by
the system itself (by default address 6); the 7 remaining addresses
may be configured by the customer. SCSI-2 speci£es that the
cable should be no more than 6 meters.

Digital's SCSI Recommendations
To reduce potential problems with signal integrity that may occur
when transmission lines are poorly matched, Digital recommends:

• Cables should be no more than 4 meters.
• Use cables and terminators that are supplied by Digital.
• Connect no more than 3 expansion boxes to the VAXstation
3100 SCSI port. Remember the following:
Seven SCSI IDs are available for customer configuration.
Multiple SCSI devices may be housed in one expansion
bOL Count the number of SCSI devices (total cannot
exceed 7) and the number of expansion boxes (total cannot
exceed 3).
• In the future, some SCSI devices may not be housed in an
expansion box. Again, count the number of SCSI devices when
you configure your VAXstation 3100 system.

Connecting to a ThinWire Ethernet Network
When verifying the position of the ThinWIre Ethernet or standard
Ethernet network select button, remember the following:

• OUT position -standard Ethernet
• IN pOSItion - ThinW1l"e Ethernet

VAXstation 3100 Shutdown Procedures
Refer to your operating system documentation for shutdown
procedures before turning off your VAXstation 3100 system and
SCSI devices. Devices may not be added to the SCSI bus, removed
from the SCSI bus, or re-cabled while the operating system is
running.

Caution: Failure to meet this requirement may cause loss of user
data or system failure.
The order for hardware shutdown is:
1

Expansion box

Monitor and peripheral device

System unit

Display Monitors
Digital provides customers with the opportunity to select a
display monitor from an offering of several models. Digital's
newest monitor for the VAXstation 3100 workstation is a 16inch color display monitor that utilizes Trinitron technology.
As new products are offered for use with the VAXstation 3100
product family, configuration rules may change. For example, the
VAXstation 3100 system unit automatically adjusts itself to the
correct voltage. Likewise, some of the new monitors automatically
adjust to the correct voltage. Refer to your monitor guide to learn
the new features specific to the product you ordered.

Errata
The VAXstation 3100 documentation indicates that the erase disk
utility formats a hard disk. Please note the following in your
documentation: the erase disk utility erases all data on a specified
hard disk. Formatting of a Digital hard disk is unnecessary.
Add the following changes to your VAXstation 3100 Model 38
documentation:
• Add to Table ~~ System Specifications:
Input voltage - Automatically adjusting AC input.
Range: 100 to 120 VAC, and 220 to 240 VAC
Input current - 5.8 Amps @ 100 to 120 VAC and 3.2
Amps @ 220 to 240 VAC (maximum current for a system
and monitor)
Power consumption - 348 Watts maximum

• Change line 11 in the example on page 7-15, Section 7.6, to:

Note: the number of megabytes displayed on line 10 (for the
RRD40) varies with the size of the £les on your compact disc.
• Change the text at the top of page 9-44 to:
If you do not have a tape or a diskette drive, the first, second,
and third hard disks go on the drive plate in positions 3, 4,
and 2, in that order. See Figure 1.
