page.
2. How do I verify the network connection between my workstation and the
SNMP-NV6 card?
Answer:
Check the network connection by typing the following command
ping
HostName or IP
address at your workstation.
3. In the Web Browser, I can see the Login page but cannot login.
Answer: Please check the IP address of the SNMP-NV6 card and the PC you trying to
login from. If both of the IP addresses are not in the same LAN, run the
EzSetting program to configure the User Limitation to Allow Any.
4. How do I refresh the NetBIOS table in Windows operating system?
Answer: Sometimes the IP address of the SNMP-NV6 card will be changed, but the
host name will remain the same. Although Windows will update its NetBIOS
table periodically, you can force it to purge its cache immediately by typing the
command nbtstat –R in the shell. After that, you can connect to the SNMP-
NV6 card by its host name.
5. How can I get the IP address and MAC address of my computer?
Answer: For Windows system: type ipconfig /all at the DOS prompt. For UNIX system:
enter ifconfig in the shell.
6. I am unable to ping or connect to the SNMP-NV6 card?
Answer: Check the following items:
1) Check all the network connections.
2) Ensure that your PC and the SNMP-NV6 card are in the same network
segment. If you don't have a router, they must be in the same network
segment.
3) You can connect to the SNMP-NV6 card only, if your PC and the SNMP-NV6
cards are using the IP addresses from the same IP address block. Normally,
private LANs use the IP addresses from one of the following blocks.
10.0.0.0 ~ 10.255.255.255
172.16.0.0 ~ 172.31.255.255
192.168.0.0 ~ 192.168.255.255
The SNMP-NV6 card's default IP address (192.168.1.100) is from the last
block. If your LAN is using a different address block, you will not be able to
connect to the SNMP-NV6 card via the LAN.
Under such situation, you can choose to:
