Paradyne 3172, 3174 manual Quick Start Procedure, Ferrite Choke

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 ACCULINK 317x E1 Data Service Unit/Channel Service Unit Operator’s Guide for more information.

Procedure

1.The DSU/CSU is shipped with a power cable appropriate to the country of 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 Operator’s Guide.

2.Attach the DSU/CSU network connection to the E1 network using the appropriate cable. Attach the DSU/CSU to the customer premises equipment via the DTE and port connectors.

3.Install ferrite chokes on cables attached to Ports 1 and 2 (Model 3172) or Ports 1–4 (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 choke with a cable tie.

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.Power on the DSU/CSU to perform the power-up self-test.

6.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.

7.If you intend to manage the DSU/CSU with SNMP, cable either the COM or AUX port (as appropriate for your configuration). Then, configure the SNMP management link.

8.If you do not intend to use the DTE Drop/Insert E1 port, disable it using the configuration procedures in Operation and Configuration Options of the Operator’s Guide. (The default setting for this port is Enabled.)

9.Configure the ports and channels you intend to use and assign channels to the network interface.
