Problems with MSE
Check the received power at ODU. If it is OK, switch off the opposite ODU and scan the band
(Radio / analyzer). By this, you will find the background noise in a given band. If the problem is
not caused by noise, check the RF cable (connectors, shielding and so on).
Problems with Failing Link
Check the counters on RFI (Count / rfi/hsi), erase (button Clear) and check the counters on RFI
again. If there are errors (the frames are not counted, the error frames are counted) check MSE
(General / status – MSE) and Rx Level at ODU (General / status – Rx Level). If you still face
problem, follow the instructions as mentioned earlier.
Problems with Ethernet Connection
Check the setup (Ports / parameters) of LAN ports. The setup has to be the same as setup on
the opposite terminal (switch, PC, router and so on). Try to analyze the problem with the help of
frame counters (Count / LAN basic) and detailed counters (Count / LAN detailed).
Problems with IP Management
IP parameters get saved in the memory only after device reboot. Change in the IP address can
be a router problem (before change of arp table). You can display the actual adjusted
parameters including the counters by the command “sh IP stat” (count / IP), actual routers by the
command “sh IP route” (IP / route).
Use program “ping ip_address_of_your_device” from Personal Computer and trace counters via
Personal Computer serial console (“sh ip stat”). Use “ping ip_address_your_PC” from device and
trace counters; Use “ping ip_address_starting_gate”, eventually “ping
ip_address_device_with_the_same_subnet” and trace printout and counters. With incorrect
visualization of opposite device status, check the IP address setup of remote rfi (“sh ip conf”) (IP /
address).
