Emerson FP20-6TX2TX KJ1611X1-BA1 12P4448X032 is intended for compatible DeltaV control-network installations that use 10/100BASE-TX copper Ethernet, RJ45 field connections, a nominal 24 VDC supply, and supported DeltaV switch-management tools.
Compatibility requires verification of the complete switch identity, copper-port configuration, network topology, firmware and configuration support, power and grounding design, cabinet environment, redundancy method, and port-security settings. Do not substitute a fiber-uplink FP20 variant or another VE6041 configuration without reviewing the controlled Emerson network documentation.
Lifecycle and support status for DeltaV Smart Switch hardware can vary by ordering number, system release, and service program. Confirm current availability, supported firmware, cybersecurity guidance, and migration recommendations for FP20-6TX2TX and its associated assembly references with Emerson before planning a new installation.
For replacement, preserve the eight-port all-copper architecture, six access-port and two uplink-port arrangement, 24 VDC supply, grounding, DIN-rail installation, network addressing, redundancy design, port locking, and managed-switch configuration. Back up the approved network settings and revalidate communications and diagnostics after commissioning the replacement.
