  2. Verify that the SNMP Port specified during installation (161 by default) is not blocked for inbound communications by a firewall.

  3. Verify that SNMPv1 is enabled in the PowerChute.

  4. Verify that the Community Name specified in PowerChute matches the Community Name used by the NMS. The Community Name is case sensitive.

  5. Verify that the NMS IP or Hostname specified in PowerChute matches the IP/Hostname of the NMS.

  6. Verify that the Access Type specified in PowerChute is set to Read for SNMP Get requests, or Read/Write for SNMP Set requests.

The Network Management System (NMS) cannot connect to PowerChute via SNMPv3:

  1. Verify that there is a network connection between the NMS and PowerChute.

  2. Verify that the SNMP Port specified during installation (161 by default) is not blocked for inbound communications by a firewall.

  3. Verify that SNMPv3 is enabled in the PowerChute.

  4. Verify that the User Name specified in PowerChute matches the User Name used by the NMS. The user name is case sensitive.

  5. Verify that the Authentication Protocol. Authentication Passphrase, Privacy Protocol and Privacy Passphrase used by the NMS match those specified in PowerChute.

SNMP Traps sent by PowerChute are not received by the NMS:

  1. Verify that there is a network connection between PowerChute and the NMS.

  2. Verify that a Trap receiver has been added in PowerChute:

    • Verify that the UDP Port specified (162 by default) is not blocked for outbound communications by a firewall.

    • Verify that the SNMPv1 Community Name, or SNMPv3 User Profile used to send the Trap is configured in the NMS.

    • Verify that the Privacy Protocol selected is compatible with the Java JRE used by PowerChute:

    • Verify that the SNMP Trap Receiver Test was successful.
