Good Morning ,

This morning we had a overreaction by our maintenance group. They replaced a bunch of 22-COMM -E cards , without setting IP Addresses . Because of time they are running them in local. What I would like to do is put all the cards they took out and assign them their IP Addresses outside their drives and install later . The IP Addresses stay on the cards in and out of the drives , correct ?

Thanks again ,

Correct.

You will need to install each of the the 22-COMM-Es onto a 'live' VFD in order to set an IP Address either via on-board HIM module or BOOTP Server (if the communication modules are still DHCP enabled).

"if the communication modules are still DHCP enabled "

If not , how do I enable DHCP again ?

Depending on your switches, this may be an option for you. I'm a bit vague since our IT guy is the one who does the Cisco config.

Set the cisco switch as a DHCP server
Set the address 'range' for each port to begin and end on only one address.
- 192.168.2.81 for port 1, 192.168.2.82 for port 2, etc
Any DHCP enabled device that plugs into one of the ports set up this way will get the 'right' IP address.
*DON'T MIX UP THE CABLES!*

We have labels that strap around the cat6 and can be read - not easily, but they can be read.

The only negative I have found is that when you are trouble-shooting a cable, you can't plug into another port to verify whether it is a switch port problem or a cable end problem. You need to bother an IT guy to change the config of the switch, or check if the port is working for you.
 
DHCP =..."a network management protocol used on TCP/IP networks whereby a DHCP server dynamically assigns an IP address and other network configuration parameters to each device on a network so they can communicate with other IP networks."

All new Ethernet devices are defaulted to 'DHCP Enabled'; in order to set a Static IP Address one would need to disable DHCP; BOOTP Server is a network utility which allows the disabling of DHCP and the setting of a static IP Address.

Most of the automation world Ethernet devices carry static IP Addresses; if your 22-COMM-E adapters were previously functional, they most likely have a static IP Address assigned.
