Ethernet Troubleshooting

Troubleshoot Ethernet connection issues caused by hardware or network configuration problems.

Use this when a device connected by Ethernet isn't responding, transaction prompts won't display, or the Ethernet cable is physically damaged.

Symptoms

You may see one or more of the following:

• The device isn't responding
• Transaction prompts don't display
• Physical damage to the Ethernet cable

Most likely cause: a loose or damaged Ethernet cable, or an incorrect network configuration.

Resolve the issue

1

Check the hardware

Trace the cable connection from the back of the device and confirm all cables, including the Ethernet cable, are securely connected.

• If the Ethernet cable is damaged, it needs to be replaced — contact your Helpdesk to arrange a replacement.

✅ Issue fixed — stop here. ❌ Still not working — continue to the next step.

2

Check the network configuration

Access Comm Control or System Mode to review the device's network configuration. See Network Configurations for what each field means.

• If the configuration is incorrect, adjust it using the correct values from your company's Level 1 Helpdesk, Merchant Services Provider, or Verifone.

✅ Issue fixed — stop here. ❌ Still not working — continue to escalation below.
