Frequently Asked Questions - EKI-9728G-4X8CI Advantech

Default username is admin and password is admin. For security, change the password immediately after first login.
How do I configure VLANs on this switch?
Access the web interface, go to Switching > VLAN. Create VLANs, assign tagged/untagged ports. Use 802.1Q tagging for trunks. Refer to the manual for advanced options like VLAN translation.
Can I use SFP modules from other vendors?
Yes, the switch supports standard SFP/SFP+ modules. However, Advantech recommends using their own modules for best performance and compatibility. Third-party modules may require manual configuration.
How do I update the firmware?
Download the latest firmware from Advantech support website. Connect via web GUI, go to Maintenance > Firmware Upgrade, upload the file, and reboot. Do not power off during upgrade.
What is the maximum cable length for RJ45 ports?
Standard Ethernet cables (Cat5e or higher) support up to 100 meters. For longer distances, use fiber optic SFP modules.
How do I enable SNMP on the switch?
Go to Management > SNMP. Enable SNMP agent, set SNMPv2c community string (e.g., public) or configure SNMPv3 with user authentication. Also configure trap destinations.
What is the purpose of the console port?
The console port (RJ45) provides out-of-band management via a serial connection (RS-232). Use it for initial configuration or troubleshooting when the network is down. Settings: 115200 baud, 8 data bits, no parity, 1 stop bit.
How do I set up link aggregation (LACP)?
Navigate to Switching > Link Aggregation. Create a trunk group, assign member ports, and select LACP mode (active or passive). Ensure the peer device supports LACP and is configured accordingly.
The switch is overheating. What should I do?
Check that the ambient temperature is within range (-10°C to 60°C). Ensure proper airflow around the vents. If fanless, verify the unit is not in direct sunlight or near heat sources. For fan-equipped models, ensure the fan is spinning. Contact support if issue persists.
