5. Troubleshooting

If you encounter a problem when you install or operate the Plug and Play Phone
Line Manager XLO unit, please review this section for likely causes and what to do
if you eliminate these possibilities, and the problem continues to occur.

5.1 Common Problems and Solutions

Problem 1—Power LED does not light.
Check whether the power supply is properly connected to the power receptacle on
the back panel of the Plug and Play Phone Line Manager XLO. Also, check
whether the power supply is connected to a live power outlet. Verify that the power
supply connected to the Plug and Play Phone Line Manager XLO is the original
power supply provided with the Plug and Play Phone Line Manager XLO.
Problem 2—IST Port receives no dial tone when going "OFF Hook."
First, determine whether a LINE Port is available (not being used by another IST
Port). Second, check the switch settings on the front panel of the Plug and Play
Phone Line Manager XLO. All switch settings corresponding to the Line
Present/Not Present switches should be in the "ON" position for each LINE Port
that a live telephone line is connected to. The Line Present/Not Present switches
should be in the "OFF" position for each LINE Port that does not have a live
telephone line connected to it. Third, check the telephone line before it is
connected to the Plug and Play Phone Line Manager XLO for dial tone. Fourth,
verify that the telephone line cords connected to the LINE Ports and IST Ports are
working properly.
Problem 3—Modem or other IST device does not access dial tone on outgoing calls.
Check all connections for proper installation. Determine whether the IST Port that
the modem is connected to is operating properly. Do this by connecting a standard
telephone to that port. If you receive dial tone when going "OFF Hook" with the
telephone, the Plug and Play Phone Line Manager XLO is operating properly.
Check the Operations/User's Manual of the modem or other IST device for
proper operating procedures for that device. Try all of the troubleshooting
solutions listed in Problem 2.
