Installing the DSU
"Procedure
To install the DSU:
1. Plug the end of the power cord into the POWER jack on the DSU. Plug the
power transformer into an ac outlet.
CAUTION:
Use no power supply except the one provided with the DSU. Using the
wrong power supply can destroy the DSU.
2. Plug the 8-pin connector on the RJ48S network cable into the NETWORK
connector on the DSU. Plug the other end of the cable into the RJ48S
modular jack.
3. Plug one end of the 34-pin V.35 cable into the DTE port of the DSU. Plug the
other end of the V.35 cable into the DTE connector.
4. Plug the 25-pin end of an EIA-232 cable into the TERMINAL port of the DSU.
Plug the other end of the cable into the VT100-compatible user interface

NOTES:
Your terminal or PC software must be set to communicate at a rate of
9.6 kbps, using characters of 8 bits, one stop bit, and no parity.
If you connect an external modem instead of an asynchronous terminal or
PC:
— Use an EIA-232 crossover cable as described in Appendix C,
Cables and
Pin Assignments, in the User’s Guide.
— If possible, configure your modem to use standard RS232 detection and
control for CTS, DSR, DTR, LSD, and RTS.
— If possible, disable AT commands on your modem.

reliable operation of the product and to protect it from overheating, these
slots and openings must not be blocked or covered.
3. Do not allow anything to rest on the power cord and do not locate the product
where persons will walk on the power cord.
4. Do not attempt to service this product yourself, as opening or removing
covers may expose you to dangerous high voltage points or other risks. Refer
all servicing to qualified service personnel.
5. General purpose cables are provided with this product. Special cables, which
may be required by the regulatory inspection authority for the installation site,
are the responsibility of the customer.
6. When installed in the final configuration, the product must comply with the
applicable Safety Standards and regulatory requirements of the country in
which it is installed. If necessary, consult with the appropriate regulatory
agencies and inspection authorities to ensure compliance.
7. Input power to this product must be provided by one of the following: (1) a UL
Listed/CSA certified power source with a Class 2 or Limited Power Source
(LPS) output for use in North America, or (2) a certified power source with a
Safety Extra Low Voltage (SELV) output for use in the country of installation.
8. A rare phenomenon can create a voltage potential between the earth
grounds of two or more buildings. If products installed in separate buildings
are interconnected, the voltage potential may cause a hazardous condition.
Consult a qualified electrical consultant to determine whether or not this
phenomenon exists and, if necessary, implement corrective action prior to
interconnecting the products.
9. In addition, if the equipment is to be used with telecommunications circuits,
take the following precautions:
— Never install telephone wiring during a lightning storm.

telephone line has been disconnected at the network interface.
— Use caution when installing or modifying telephone lines.
— Avoid using a telephone (other than a cordless type) during an electrical
storm. There may be a remote risk of electric shock from lightning.
— Do not use the telephone to report a gas leak in the vicinity of the leak.

Notice to Users of the Canadian Telephone Network
The Industry Canada label identifies certified equipment. This certification means
that the equipment meets telecommunications network protective, operational
and safety requirements as prescribed in the appropriate Terminal Equipment
Technical Requirements document(s). The Department does not guarantee the
equipment will operate to the user’s satisfaction.
Before installing this equipment, users should ensure that it is permissible to be
connected to the facilities of the local telecommunications company. The
equipment must also be installed using an acceptable method of connection. The
customer should be aware that compliance with the above conditions may not
prevent degradation of service in some situations.
Repairs to certified equipment should be coordinated by a representative
designated by the supplier. Any repairs or alterations made by the user to this
equipment, or equipment malfunctions, may give the telecommunications
company cause to request to disconnect the equipment.
Users should ensure for their own protection that the electrical ground
connections of the power utility, telephone lines and internal metallic water pipe
system, if present, are connected together. This precaution may be particularly
important in rural areas.
CAUTION:
Users should not attempt to make such connections themselves, but
should contact the appropriate electric inspection authority, or
electrician, as appropriate.
The Ringer Equivalence Number (REN) assigned to each terminal device
provides an indication of the maximum number of terminals allowed to be
connected to a telephone interface. The termination on an interface may consist
of any combination of devices subject only to the requirement that the sum of the
Ringer Equivalence Numbers of all the devices does not exceed 5.
If your equipment is in need of repair, refer to the procedures described in the
next section.
