Problems with Disconnecting NICs
Genie cameras installed in environments with physical motion, vibrations, or high EMI may be disconnected by the NIC. The following items need to be reviewed to solve the problem.
•Motion or vibrations may cause data loss because the Ethernet cable connection is not secure. Use a locking Ethernet cable (see "Ruggedized RJ45 Ethernet Cables" on page 97).
•High EMI may cause the NIC to drop data or to disconnect and reconnect at a lower data rate. Such situations do not have simple solutions and may require an expert consultant.
•Some NIC products may not tolerate any data disruptions. Any condition causing the NIC to drop the connection may make it unrecoverable. Communication with the Genie can not be reestablished without power cycling. In this case, trying a variety of NIC products is suggested.
Ethernet Switch Issues
An Ethernet switch usually works transparently and presents no problems. Review the following list when troubleshooting switch issues.
•Is the Ethernet switch powered on.
•Are all ports used configured as active; not disabled.
•Are all ports running at gigabit
•Is the switch configured to use Jumbo Frames.
•Verify the Ethernet cabling. Poor cables will cause connections to
•When using a VLAN Ethernet switch, confirm that the Genie and controlling computer are on the same VLAN group setup on that switch.
•When using a chain of switches, ensure that
Multiple Camera Issues
•When using multiple cameras with a computer with multiple NIC ports, confirm each Genie has been assigned an IP address by checking the GigE server (see "Sapera GigE Server Details" on page 83).
•Do not use multiple NIC port configured in LLA. In this case use a DHCP server or persistent IP.
•When using multiple cameras connected to an VLAN Ethernet switch, confirm that all cameras are on the same subnet setup on that switch. See "Using Genie with a VLAN Ethernet Switch" on page 18.
