This section contains the test procedures for the IBM Cabling System data
paths and includes the following tests:
• Test for cable drop from distribution panel to control unit
• Test for cable drop from distribution panel to workstations except the last
workstation on the data path
• Test for cable drop to last workstation on the data path
• Test for cable drop between distribution panels.
A typical IBM Cabling System data path is shown in Figure 65. A test
connector like the one shown in Figure 59 on page 125 is needed for these
tests.
