Troubleshooting - Tripp Lite TLNETCARD User Manual

6. Troubleshooting

1. How do I confirm the link between the TLNETCARD and the UPS is established?
If the link between the TLNETCARD and the UPS is correctly established, the yellow LED on the TLNETCARD Network port should flash
rapidly.
2. I can access the TLNET Supervisor, but I cannot login.
Check the IP addresses of the TLNETCARD and the workstation on which you are trying to log in. By default, they must be within the same
LAN. To enable external connections, launch the TLNET Configurator and for that device's configuration, change User Limitation to Allow Any,
as shown below.
3. I am unable to connect to the TLNETCARD via its Host Name
If you just assigned a new static IP address to the TLNETCARD, you may need to refresh the NetBIOS table so that it corresponds with the
new setting. Although Windows updates its NetBIOS table periodically, you can manually force it to refresh by entering nbtstat –R in DOS
prompt mode. After that, you should be able to connect to the TLNETCARD its Host Name. Ensure that the Host Name assigned to the
TLNETCARD does not exceed 16 bytes.
4. I am unable to ping the TLNETCARD from my workstation
If the SNMP IPv6 is non-responsive, check the following:
a) If the green LED on the TLNETCARD's Network port is off, check that the network cable is correctly connected from the TLNETCARD to
the network equipment.
b) If the green LED is on, the current IP address may be unreachable. Manually assign a valid IP address to the TLNETCARD.
c) If the green LED flashes and your network configuration includes a DHCP server, verify that the DHCP service is working properly.
Otherwise, verify that the IP address is not already assigned to another device on the network. Note that if the current configuration
is not useable, the TLNETCARD will reset to default IP settings (IPv4 address: 192.168.1.100/ net mask: 255.255.255.0/ gateway:
192.168.1.254).
d) If the problem persists, use a network cable to cross link the TLNETCARD and the workstation. Ping the TLNETCARD's default or assigned
static IP address. If the ping is successful, indicating that the TLNETCARD is working properly, check your network equipment. If not,
contact your local dealer or service personnel for assistance.
5. I am unable to perform an SNMP Get or Set command
Refer to 3.3.2 Notification to check SNMP settings. Verify that the workstation's IP address is added to the NMS IP list with Read or Read/
Write (for Set) access. The community string on the workstation and the SNMP IPv6 must match.
6. I am unable to receive an SNMP trap
Refer to 3.3.2 Notification to check SNMP Trap settings. Verify that the workstation's IP address is added to the Target IP list.
