S.CON1M/MA System
17
11 – DIP Switches Setting
Each S.CON1M/MA unit is equipped with an array of DIP switches that facilitate the
proper setting of the TP and F/O ports for optimal operation.
Each port may have different settings.
A wrong setting will not necessarily result in a channel malfunction, but rather in non-
optimal operation (for instance - HDX operation instead of FDX).
The switches are recessed in the front panel to avoid incidental change of position.
Use a flat-head miniature screwdriver (or a similar tool), insert it through the slot, hold it
vertically to the panel against the switch to be set, and change its position up or down
according to the following table.
The below table shows that the S.CON1M/MA is configured in Auto-Negotiation mode.
The VLAN mode (when enabled via S7) implies that the internal management port
and the TP port form one VLAN. For local SNMP management (SNMP Manager
connected to local TP port) set switch the S7 to down position (VLAN enabled)
For remote SNMP management (SNMP manager station connected to remote
network), ensure that S7 is in UP position (VLAN disable)
