•
Verify that the Ethernet connection on the IEC has a heartbeat (i.e. both green lights around the
Ethernet port are lit). If not, check the cable connections.

Verify that the Ethernet cable is securely connected to the IEC and Ethernet port on a
wall/floor/cubicle/switch/router.

If the Ethernet cable is connected to an Ethernet port that is in a wall, floor, or cubicle, verify that
it is a working port by connecting another networked device into that port and accessing the network.

Unplug the IEC from the electrical outlet and plug it in again. If it is connected to a power controller,
recycle power thru the power controller.
recycle power thru the power controller.
•
Verify network connectivity by pinging to the IEC. If the ping test failed, check the network settings
on the device and Cisco IEM as well as the IP addresses, subnet masks and default gateways. If you
can ping to the IEC, the issue is not network connectivity. Troubleshoot the operating system and
browser.

Multiple IEMs on a Single Network
If more than one IEM is on the network, use static addressing. DHCP will only work for one of the IEMs.
IP Address Not Correct in Virtual Machine
If you are running Network Address Translation (NAT) as the virtual network cards, the virtual machine
will not pick up the IP address. Choose Bridged for the virtual network cards instead.
