Quick Start Procedure
The following procedure is for experienced DSU/CSU users who are familiar with the
3160/3164 DSU/CSU installation process and have no special requirements for their
application. See the
ACCULINK 316x Data Service Unit/Channel Service Unit
Operator’s Guide for more information.
1. Attach the power cord to the rear of the DSU/CSU and the other end to a grounded
115 Vac power outlet.
2. Attach the 3160/3164 DSU/CSU network connection to the T1 network using the
appropriate cable. Attach the 3160/3164 DSU/CSU to the customer premises
equipment via the DTE (DSX-1) and/or port connectors.
3. Power on the DSU/CSU to perform the power-up self-test.
4. If you intend to use front panel emulation, connect the cable from the PC to the
COM port on the rear panel of the DSU/CSU.
5. If you intend to manage the 3160/3164 DSU/CSU with SNMP, cable either the
COM or MODEM port (as appropriate for your configuration). Then, configure the
SNMP management link.
6. If you do not intend to use the DTE Drop/Insert T1 port, disable it using the
configuration procedures in Chapter 3,
Operation , and Appendix C, Configuration
Options
, of the Operator’s Guide . (The default setting for this port is Enabled.)
7. The Factory 1 configuration for ESF framing format and B8ZS line coding format is
the default configuration and is appropriate for most networks. If this configuration
does not work for you, try the Factory 2 configuration for D4 framing format and
AMI line coding format. To further customize configuration options, refer to
Changing Configuration Options in Chapter 3, Operation , and to Appendix C,
Configuration Options , in the Operator’s Guide .
8. During the power-up self-test, the FAIL LED flashes, then all LEDs blink twice.
When the test is complete, verify that the DSU/CSU is functional by observing that
the OK, NETWORK SIG, and DTE SIG LEDs are lit.
9. Configure the ports and channels you intend to use and assign channels to the
network interface.

Important Safety Instructions
1. Read and follow all warning notices and instructions marked on the product or
included in the manual.
2. This product is intended to be used with a 3-wire grounding type plug – a plug
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 until a qualified 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.
3. Slots and openings in the cabinet are provided for ventilation. To ensure reliable
operation of the product and to protect it from overheating, these slots and
openings must not be blocked or covered.
4. Do not allow anything to rest on the power cord and do not locate the product
where persons will walk on the power cord.
5. 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.
6. 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.
7. 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.
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. Input power to the ac voltage configuration of this product must be provided by a
UL-listed or CSA-certified power source with a Class 2 or Limited Power Source
(LPS) output. Input power to the dc voltage configurations of this product must be
provided by a National Electric Code (NEC) or a Canadian Electric Code (CEC)
Class 2 circuit.
10. This product contains a coin cell lithium battery that is only to be replaced at the
factory. Caution: There is a danger of explosion if the battery is incorrectly
replaced. Replace only with the same type. Dispose of used batteries according to
the battery manufacturer’s instructions. Attention: Il y a danger d’explosion s’il y a
remplacement incorrect de la batterie. Remplacer uniquement avec une batterie du
même type. Mettre au rebut les batteries usagées conformément aux instructions
du fabricant.
