(isolated) ground circuit.
1 Verify Site Preparation
You may have received a copy of the system Site Preparation manual, which
describes the physical, environmental, and electrical requirements for your
system. A copy of that manual is also included in your Customer Hardware
Information Kit. If you have not done so, read that manual and follow its
instructions for preparing your site.
• The installation instructions that follow assume your site meets all the
requirements listed in the Site Preparation manual.
• These instructions also assume all terminal data lines, telephone lines,
and network lines that you plan to connect to your system are in place
and clearly labeled.
You will need the following tools to install your system. They are not
included in your shipment.
• Scissors
• Phillips (cross point) screwdriver
• Adjustable wrench
If you are installing a dual-host system, you must repeat each step in the
installation procedure for each host.
2 Check the Shipment
Before unpacking your system, find the Product Delivery Document. It is
attached to the outside of a carton and is labeled with a blue "i" symbol.
That document lists your order and how it breaks out into the items
shipped.
Your shipment may include several cartons:
• One carton contains the system.
• A smaller carton contains the console terminal, if ordered.
• Another carton contains hardware documentation, software documen-
tation, and software licenses. That carton also contains system software
and diagnostic software if you ordered those items separately.
VAX 4000 Model 200 (BA215) Installation 1
Depending on your order, your shipment may also include cartons
containing:
• Additional terminal(s)
• Printer(s)
• Modem(s)
• Expander(s)
Make sure your shipment is complete by checking that each item listed as
shipped on the Product Delivery Document appears on a Content Listing
or on a barcode label on the outside of one of the cartons in your shipment.
NOTE: Save all packing materials until you are sure you will not reship
any items in the shipment. And save all items in the shipment until you are
sure you will not use them.
Use the unpacking illustrations on the cartons as a guide to unpack your
shipment, one carton at a time. Check the contents of each carton against
the Content Listing on its side to ensure you received all items.
Release the shipping brackets according to the instructions on the yellow
label attached to the front of the system. Then remove the yellow label.
WARNING: The system weighs 38.5 kilograms (85 pounds) with all options
installed. Two or more people should move the system.
If any item is missing or damaged:
• Contact your delivery agent.
• Contact your Digital sales representative.
If you ordered a dual-host system, the carton containing the second system
includes the same items as the first carton plus a BC21M–09 DSSI cable.
DSSI stands for Digital Storage Systems Interconnect.

WARNING: Do not use the hand holds to lift the system.
• Roll it sideways.
• Slide or walk it backward or forward by gripping the hand holds on the
side.
Leave space behind the system for routing cables. Once installation is
complete, you can place the system base directly against a wall. The
oversized base ensures enough space for proper ventilation.
The next step in installing your system is to install the console terminal.
4 Install the Console Terminal
You will use the console terminal to communicate with your system.
1. Unpack the terminal and its documentation.
2. Use the instructions in the terminal installation guide to connect the
various parts of the terminal.
3. Turn on the terminal.
The terminal performs a self-test. The documentation for the terminal
describes a successful self-test and error messages you receive if the
terminal is not operating properly.
Once the terminal passes its self-test, you are ready to perform setup
operations.
4.1 Perform Setup Operations
Setup instructions for terminals vary according to model or according to
which read-only memory (ROM) is installed in the terminal. Be sure to:
• Read the documentation provided with your terminal.
• Follow the setup instructions for your terminal.
NOTE: A new terminal from Digital has the baud rate set to 9600. If your
terminal is new and you want to use that rate, you can skip the baud rate
setup instructions.
If you have a dual-host system, you can use one terminal with dual sessions
instead of two terminals. See your terminal documentation for instructions.
Once you test the terminal and perform setup operations, you are ready to
connect the terminal to your system.
VAX 4000 Model 200 (BA215) Installation 5
4.2 Connect the Terminal to the System
You will attach one end of a cable to the CPU cover panel and the other
end of the cable to a communication port on the back of the terminal.
• The CPU cover panel is on the front of the system and covers backplane
slots 1 and 2.
• The port on the back of the terminal varies with the type of terminal.
Refer to the instructions that follow to connect a VT300-series or VT400-
