Troubleshooting

If you find problems in your network, check following points: 

Check Network Status

Network Status can be check in two ways: 

modem LEDs state

The modem has two status LEDs: LED Medium: Only for Coaxial (Green) 

or Hybrid (Orange) and  a link status LED: Connection  Optima (Green), Normal  (Orange) or 
poor   (Red).   Check   the   color   of   the   LEDs   to   verify   that   the   installation   was   successful, 
particularly if the status LED is light off no connectivity with any other device. 

CoaxManager

: Connect the application CoaxManager to master device on headendand check 

the network includes all slave modems and link status is rigth. Check that you have correctly 
configured   modems:   MxU   Mode/HomeNetworking,   Master/Slave,     Network   Key   ,...For 
questions about how to configure the modem See CoaxManager Manual. 

In MxU Installations some modems don't appear

If   any   slave   modem   is   installed   fails   or   does   not   appear   in   the   device   list   check   the   following 
assumptions: 

Verify slave  modem  is operating (CoaxManager   can  connect  to)  and leds  are  lighted 
(Coaxial/Hybrid led, link state led and Ethernet leds). Check led colours are right: green, 
red or orange. 

Verify  slave  modem  is configured    correctly  and check  that NPW  (Network password 
key), transmission mode and transmission mask is set to appropriate values.

Verify distance between master and slave farthest. Not recommended distances

 greater 

than 1 km. 

If you are using AccessControl™ Sofware or used it earlier in the installation, verify that 
the device is enable for transmissions.  Please note that AccessControl can enable or 
disable device transmissions.
