The GE IS420ESWBH1AE, also cataloged as the IS420ESWB Ethernet IONet Switch, operates as a dedicated hardware component for deterministic industrial communication and real-time control network switching within GE Mark VIe and Mark VIeS platforms. The switch bridges sixteen 100Base-TX copper RJ45 channels with one 100Base-FX multi-mode fiber-optic port via LC connectors to route unmanaged time-critical telemetry across control racks.

Backplane Bus Communication Velocity and Network Density Scaling
The IS420ESWBH1AE manages local backplane bus communication velocity across distributed control node topologies, using high-density port arrays to maintain deterministic Ethernet data frame transport. Through hardware-level firmware flash compatibility, the unit provides zero-configuration boot sequences while preventing packet collisions across high-density I/O clusters. The dedicated 100Base-FX LC multi-mode fiber interface isolates noise-sensitive long-distance cabinet links from local copper loop transients.
Frequently Asked Questions
Q: What power input voltage range does the IS420ESWBH1AE switch accept?
A: The switch operates on nominal 24 / 28 VDC redundant power supply connections to maintain uninterrupted network fabric availability.
Q: What type of fiber-optic cabling is required for the single optic port on this model?
A: The onboard fiber port requires 100Base-FX multi-mode fiber terminated with a standard duplex LC-type connector.
Q: Can the IS420ESWBH1AE be mounted directly on a standard DIN-rail inside an enclosure?
A: Yes, the unit is constructed with a vertical DIN-rail mounting chassis designed for direct mechanical snap-on installation within industrial control cabinets.
Field Installation Guidelines
- Mount the switch vertically onto a grounded 35 mm DIN-rail inside the control enclosure, ensuring top and bottom ventilation clearances of at least 50 mm.
- Connect primary and secondary 24 / 28 VDC power feeds to the removable terminal block, observing proper terminal polarity.
- Attach chassis earth ground directly to the dedicated earthing stud using a short, low-impedance copper wire strap.
- Plug field Ethernet cables into the 100Base-TX RJ45 copper ports (1 through 16) until retaining clips snap into position.
- Clean the fiber optical interface end-face before inserting the LC multi-mode connector into the 100Base-FX fiber socket.
