Why the Work Mattered

Purpose and Operating Need

The OT fiber cutover required field-level understanding of what Studio 5000 can monitor, what must be configured through Stratix Device Manager or CLI, and how trunk uplinks, native VLANs, LACP, REP, and CIP traffic behave.

Engineering Approach

Engineering Approach

Worked through StackWise naming, LACP active mode, Port-Channel / EtherChannel validation, managed access switches / 5800 capabilities, SmartPort order of operations, REP / DLR concepts, VLAN native-port setup, Studio 5000 AOP monitoring limits, firmware.tar upgrades, boot-variable recovery, Express Setup, EIPMOD alarm troubleshooting, Alarm Out faults, and CIP class distinctions between HMI, VFD, and POINT I/O communications.

Engineering scope and design basis

Reduced dependence on external IT during OT cutovers and improved ability to diagnose live network faults during commissioning.

Improved OT commissioning and cutover readiness, measured by defined configuration sequence, LACP uplink standard, Studio 5000 / Stratix monitoring boundary, CIP Class 1 versus Class 3 understanding, and practical fault-recovery procedures, by building a field-usable OT switch configuration and troubleshooting playbook.

Project ownership and delivery context

Owned the full project lifecycle: capital planning and prioritization, need definition, feasibility and scope development, engineering and AFE justification, procurement and vendor coordination, construction sequencing and field oversight, commissioning, turnover, and post-startup support. Connected operating requirements with technical scope, funding decisions, execution readiness, and the needs of operations and maintenance.

Developed the fiber and managed-switch architecture, resilient power arrangements, configuration and rollback requirements, and cutover sequence. Network drawings, device labeling and validation connected the installation with operator and maintenance needs. The work included a 10 Gbps backbone and 13 UPS-backed resilience points.
