Functional Design and Network Management
The GE IS420ESWBH3A connects directly to the Mark VIe backplane for power. It forwards IONet packets between controllers and I/O packs. Then, this switch supports IGMP snooping for multicast traffic filtering. Onboard LEDs indicate port link status and activity. Therefore, the IS420ESWBH3A simplifies troubleshooting of network connectivity issues.
Installation and Compatibility Notes
You must configure the IP address before connecting to the IONet. The GE IS420ESWBH3A fits exclusively into Mark VIe series cabinets. Always replace faulty units with identical GE switch revisions. Additionally, verify that each cable meets Cat5e specifications. This practice prevents packet loss due to signal degradation.
