Module(s) failed test

Any error not listed requires that the unit be serviced.

Long test with loopback

This test is entered by pressing the ADVANCE switch only while powering up the unit

with the on/off switch. Special loopback connector should be connected to each Porter

port.

Tests 1-5

These are the same as tests 1-5 of the ‘Long test without loopback’>

Test 6 – Module test with loopback

This test verifies that all port signals are functional. In order for this test to pass, special

loopback connectors must be installed on each port, see TABLE VII. If this test fails

(see TABLE VI) then a port communication chip has failed and the unit must be serviced.

The ADVANCE switch may be pressed to determine which port is the failing port. BUF,

DATA, and BUSY will all be flashing. The LEDs of all ports which pass will be flashing. A

failing port will have its corresponding LED steadily lit. Ports not installed will have their

corresponding LEDs off. This test will continuously execute until all ports pass or the test

is bypassed. In order to bypass this test completely, both the ADVANCE and SELECT

switches may be pressed.
