Connect the SLM to the IF input cable.
Set the SLM to the appropriate known DS
frequency and measure the amplitude in
dBmV.
Verify that the peak amplitude of the IF
signal is compliant with the WMU input
signal level specification. If no signal is

10.4 Troubleshooting the NMS
If the main SNMPc window does not show the three parts of the panned window
(left, right and bottom), try to drag the pan bar. If this fails:
Exit SNMPc
1) Rename
<SNMPc directory (default: c:\program files\SNMPc Network
Manager)>\SSFAdministrator.ssf
to be <SNMPc directory>\SSFAdministrator.ssf_
2) Reinstall SNMPc
If the SNMPc installation is stuck, restart the computer and try again
If SNMPc gets corrupted (has been installed but fails to work):
Report error messages and other relevant datails to Vyyo NMS team
3) Uninstall SNMPc, according to instructions (see Appx C.4, Uninstalling
the NMS)
4) Reinstall the NMS according to instructions
5) If a ‘low virtual memory’ message appears:
Close unneeded applications
6) If the message re-occurs, report to Vyyo NMS team, close the NMS main
window and startup the NMS
