Map trusted, untrusted and service interfaces
The manufacturer source lists 4 x GbE RJ45 ports. Assign every copper, fiber, WAN and service interface to its intended security zone before ordering. Confirm connector type, transceiver requirements, link speed, redundancy and upstream equipment instead of selecting a firewall from port count alone.
Review power, temperature and enclosure design
The saved data gives Dual 12- 24 V DC and an operating reference of -40 to +70 °C. Check grounding, branch protection, cabinet temperature, ventilation, mounting clearance and cable access. Environmental approval of the device does not automatically approve the complete installed panel or network design.
Define security and software requirements
Document the intended firewall rules, routing, VPN, NAT, user access, logging, time synchronisation, configuration backup and update process. Confirm required licenses, feature packages and support scope from current manufacturer documentation; do not infer entitlement from the hardware name alone.

Plan migration or replacement
For an installed unit, export the approved configuration and record firmware, certificates, addressing, port assignments and connected equipment before removal. A visually similar device is not necessarily a drop-in replacement. Schedule validation and rollback steps appropriate to the plant cybersecurity policy.
Prepare the RFQ
Request Hirschmann IAF-240 - ESSENTIAL, part number 942355001, quantity, destination and target delivery date. Include the network diagram, security-zone plan, port schedule, power source, environmental conditions and required documentation so the quoted scope can be checked against the intended industrial application.
Receipt and lifecycle record
Compare the delivered nameplate, hardware revision and included accessories with the approved purchase line before commissioning. Retain photographs, configuration backups, license records and acceptance-test results so future maintenance can identify the exact approved security appliance.
