7 TROUBLESHOOTING
7.1 Basic Troubleshooting flow
Immediately after you fully insert the Jack-PC device into the installed Flex-Jack housing, you
sould see the Power/Fail LED illuminated green. After about 30 seconds you should see the
Link LED illuminated orange (see figure 7.1). If nothing happens - no lights – use the basic
troubleshooting flow below. If only Power is lighted – go directly to LAN troubleshooting flow
(make sure you have read Chapter 6 – LAN and wiring configurations before continuing to
the troubleshooting flow).

Naturally troubleshooting the first installation in a particular site is the most difficult. If nothing
works after initial installation completed you have several potential suspects:
• The LAN cabling
• The patch panel at the far end
• The switch at the far end
• The terminal block at the Flex-Jack housing
• The Jack-PC used for testing
• The PoE equipment
The overall motivation (as in any troubleshooting flow) is to isolate and identify the faulty
component/s. Keep in mind that there may be more than one problem!
