Quick Start Procedure
The following procedure is for experienced DSU/CSU users who are familiar with the
317x DSU/CSU installation process and have no special requirements for their
application. See the
Operator’s Guide
Procedure
The DSU/CSU is shipped with a power cable appropriate to the country of
1.
installation. Attach the power module cord to the rear of the DSU/ CSU and the other
end to a grounded AC power outlet. If you intend instead to use a 24 or –48 VDC
power supply, see the Operato r’s Guide.
Attach the DSU/CSU network connection to the E1 network using the appropriate
2.
cable. Attach the DSU/CSU to the customer premises equipment via the DTE and
port connectors.
Install ferrite chok es o n cables attached to Ports 1 and 2 (Mo del 3172) or Ports 1–4
3.
(Model 3174):
— Pull up on the latch to open
the ferrite choke.
— Place the ferrite choke on the
cable as close to the
DSU/CSU as possible.
— Close the choke around the
cable and press down on the
latch to fasten it.
— Secure the chok e with a ca b le
tie.

Important Safety Instructions
Read and follow all warning notices and instructions marked on the product or
1.
included in the manual.
This product is intended to be used with a 3-wire grounding type plug – a plug
2.
which has a grounding pin. This is a safety feature. Equipment grounding is vital to
ensure safe operation. Do not defeat the purpose of the grounding type plug by
modifying the plug or using an adapter.
Prior to installation, use an outlet tester or a voltmeter to check the AC receptacle
for the presence of earth ground. If the receptacle is not properly grounded, the
installation must not continue unti l a qua lif ied electrician has corrected the problem.
If a 3-wire grounding type power source is not available, consult a qualified
electrician to determine another method of grounding the equipment.
Slots and openings in the cabinet are provided for ventilation. To ensure reliable
3.
operation of the product and to protect it from overheating, these slots and
openings must not be blocked or covered.
Do not allow anyth ing to rest on the po wer cord a nd do not lo cate the pro duct wher e
4.
persons will walk on the power cord.
Do not attemp t to s ervice thi s p roduct your se lf, as openi ng or re moving covers may

expose you to dangerous high voltage points or other risks. Refer all servicing to
qualified service personnel.
General purpose cables are provided with this product. Special cables, which may
6.
be required by the regulatory inspection authority for the installation site, are the
responsibility of the customer.
When installed in the final configuration, the product must comply with the
7.
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.
A rare phenomenon can create a voltage potential between the earth grounds of
