Justification and Approval - LLA IGH - Cisco_Final_Redacted.pdf

This document is a J&A (Justification and Approval) Single Source Determination for Cisco networking equipment for the U.S. Army Corps of Engineers Walla Walla District. The procurement is part of the Lower Granite Turbine Intake Gate Hydraulic System Upgrade, which requires specific Cisco networking equipment including 3 managed switches (IE-3400-8P2S-E) and 7 Gigabit SFPs (GLC-SX-MM-RGD). The contract award is scheduled for 2025, with the estimated purchase price for the brand name equipment being approximately redacted, representing a small percentage of the total estimated contract price.

The justification emphasizes the need for Cisco equipment due to compatibility with the existing All-In-One Programmable Logic Controllers (PLC) system and cybersecurity requirements. The document notes that Cisco is the standard network switch used by the Generic Data Acquisition and Control System (GDACS) and is on the Department of Defense Information Network (DoDIN) Approved Products List. Alternative brands would require additional training, time, labor, and funding to program a new network system, potentially creating complications between different SCADA systems and risking non-compliance with cybersecurity standards.
