Propagation delay or delay skew gives FAIL result
• Cable is too long (may need to remove coiled service loops)
• Cable uses different insulation materials on different pairs

• Electrical devices near the cabling are generating noise pulses.
• There is an active link in the same bundle as the cabling under test.
• Verify that the tester and smart remote are operating correctly. Connect the units together and run an Autotest.
