Expected Results
The BER must be less than 1E-9 for lasting tests and display NO ERRORS for
brief ones.
Note: When placing the two TS5000 face to face you need to do:
1. Cover with a tape two of the three transmitters, leaving only one
transmitter free. Recommended distance for bench test is between
1.5 to 2m’ apart.
2. Before doing the BER test you have to verify that there are no
“reflections” from the front window: Shut down the power from
unit A and make sure that the RSSI value on unit B drops to “000”
or to the levels that the “Air RX” LED is OFF. Do the same
shutting down unit B. if you have RSSI reading when shutting
down one of the units, you need to fine align it until you get RSSI
value of “000” or the “Air RX” LED to OFF position.
3. Only when part 1 & 2 are done you can start the BER test of file
transfer test.
SNMP Management Setting and Operation
General: Given the small amount of information and parameters that the SNMP agent
module of the FSO product line deals with, the card has a moderate memory size and CPU
type. If the management Ethernet port is connected to a network with higher rate of broadcast
and multicast traffic, slow SNMP management response of the FSO may occur.
Recommendation:
The recommended solution for this symptom is to isolate the Switch port connecting the FSO
SNMP management module to the network from the network traffic by assigning it to a
dedicated VLAN usually used for network management. If possible also limit the ingress
broadcast rate to that specific port.
To set a new IP address, please refer to the “IP address setting procedure for TereScope
management card” file in the Manuals CD
