pump red light and no connection to Chromeleon

Question

I have an 1100 agilent HPLC system which gives a red light for the pump, also it makes no connection at all to Chromeleon. Anyone experienced this before? 
 
 Thankyou

Hard to troubleshoot without further details. First things first: Assign a fixed IP address to your LAN card, e.g. 192.168.254.1 with subnet mask 255.255.255.0. From the command line, see if you can ping "yourself". If not, you might have to check Windows device manager to see if the LAN card has been identified correctly. Then look at the LAN card in the LC stack (hopefully in the detector). If it's a G1369A/B/C, turn off the power, remove the card and examine the eight DIP switches on the card. All need to be down (=off position), but 5 and 6 need to be on. That's the setting for the default IP address. Reinstall the card, power on the module, connect the LAN cable from the PC to the communication card and try ping 192.168.254.11. There should be a reply.
