Nature of Problem
Suggestion
LED3 – USB LED remains RED
 This means USB communications is not successful.
Check settings of the DSE892.
 Check USB cable is USB A to USB B type cable.
 Maximum length of USB cable is 6 m unless third
party powered USB extender is used.
LED4 - LINK LED remains OFF
 LINK LED only illuminates during Factory Reset and
firmware update procedure. At all other times, the
LED remains OFF.
None of the SNMP operations are
working (TRAP, GET, SET)
 Ensure the SNMP manager is configured to SNMP
V2c.
 Check that the DSE892 network settings are correct
(verify with the IT manager of the network it is
connected to).
 Check that any firewall between the DSE892 and the
SNMP Manager is configured to allow through the
traffic on the selected SNMP port and the port number
below this if using GET and/or SET.
SNMP Traps are not being received
by the SNMP Manager
 Check that any firewall between the DSE892 and the
SNMP Manager is configured to allow through the
traffic on the selected SNMP port.
 Check that the DSE892 is set to send TRAP
messages to the correct IP address of the SNMP
Manager.
 Check that the DSE892 network settings are correct
(verify with the IT manager of the network it is
connected to).
SNMP GET is not working
 Check the SNMP manager is configured with the
correct Read Community String. This is the DSE892
GET Password.
 Check the Port number. SNMP GET uses one port
below the SNMP Trap Port.
 For example if the DSE892 is configured to use port
162 for TRAP, GET uses port 161.
SNMP SET is not working
 Check the SNMP manager is configured with the
correct Write Community String. This is the DSE892
SET Password.
 Check the Port number. SNMP SET uses one port
below the SNMP Trap Port.
 For example if the DSE892 is configured to use port
162 for TRAP, SET uses port 161.
