Step 7. Connecting the Cables
Use the completed 3708 forms in Figure 4-2 on page 4-5 and Figure 4-4 on
page 4-7 to determine which cables and devices to connect to which 3708 ports.
Connect the cables and test the 3708 as follows:
1.
Turn off the 3708.
2. Use the completed 3708 network forms to make labels for each cable as follows:
a. Obtain a cable with the desired type and length. The cable type and length
are written on the factory labels (IBM cables only) at each end of the cable.
b. Using a self-adhesive strip or similar material, make two labels that contain
the following information from the form:
• The 3708 name
• The device name
• The port number.
c. Attach one of the new labels to the 3708 end of the cable. This is the end
that has a V.ll (EIA 422A) or V.24 (EIA 232C) on the factory-installed
label.
d. Attach the other new label to the device end of the cable (opposite the
3708).
3. Connect the 3708 end of the cable to the port that is identified on the label.
Connect the device end of the cable to the device that is identified on the label.
Secure the cable by tightening the connector screws.
4. Repeat steps 1 through 3 for all the cables listed on the network form.
5. Turn on the 3708. The 3708 automatically runs a self-diagnostic test. Do not
press the Test/Normal switch.
After approximately 10 seconds, the base Not Ready light and the cartridge light
begin blinking alternately or both will be turned off. This means that the 3708
is working correctly. Refer to Chapter 2, "Using Symptoms to Solve a
Problem" in IBM 3708 Network Conversion Unit Problem Determination for
more information about the light sequences.
Note: If you have any problems, refer to IBM 3708 Network Conversion Unit
Problem Determination.
