Troubleshoot DHCP connectivity issues
Use the following tips to troubleshoot server connectivity issues:
Procedure
1. Ensure that the gas chromatograph (GC) is up and running.
2. Check that the SW1 switch is in the On position.
3. Check the following connections:
a) If you are using a Ethernet straight-through cable, ensure that the personal computer (PC) has an Ethernet network
interface card with auto-MDIX.
b) If your Ethernet network interface card does not support auto-MDIX, ensure that you are using an Ethernet crossover
patch cable.
c) Check to see if the GC's central processing unit (CPU) board link lights are on.
see Figure 28. The three Ethernet1 light-emitting diodes (LEDs) are located on the front bottom edge of the card. If
link lights are off, then check your connections. (see
