Installation Guide
- Turn off all power before starting installation.
- Choose DIN-rail or panel mounting method.
- For DIN-rail, attach the required clips first.
- Snap the switch onto the DIN rail firmly.
- For panel mount, use screws through mounting holes.
- Connect primary power to the first input terminal.
- Connect redundant power to the second input terminal.
- Use Cat 5e UTP cables with RJ45 connectors.
- Plug each device into the 16 copper ports.
- Verify LED indicators show proper link status.
- Allow 2 inches clearance for convection cooling.
Diagnostic Tips
- Check the power LED first if switch does not work.
- Look for yellow link LED to confirm 10 MB connection.
- Look for green link LED to confirm 100 MB connection.
- No link LED means cable or device problem.
- Use the activity LED to see data flow.
- Monitor duplex LED for correct negotiation settings.

Buying Guide
When you buy a GE IS420ESWBH3A IONet switch, follow these tips. First, count your network devices. This switch has 16 copper ports. Second, check if you need fiber ports. This H3 model has no fiber. Third, verify your power source. You need 18-32 VDC with dual inputs optional. Fourth, measure your cabinet space. The switch is 188 x 86 x 56 mm. Fifth, plan your mounting method. DIN-rail is easiest for new panels. Sixth, consider your temperature range. The switch works from -40°C to +70°C. Seventh, confirm your system type. This switch is for Mark VIe and VIeS only. Eighth, order spare units for critical turbines. Ninth, review warranty terms. We offer 12 months coverage. Tenth, choose your shipping method. We use FedEx, UPS, and DHL. Finally, test the switch with your existing IONet before full deployment.
