Hirschmann DRAGON MACH4000-48G+4X-L3A-UR Buyer Reference for Interfaces, Installation and Configuration-Specific Supply
Confirm the exact DRAGON switch version
Hirschmann DRAGON MACH4000-48G+4X-L3A-UR identifies the Hirschmann managed industrial rack-mount Ethernet switch, model DRAGON MACH4000-48G+4X-L3A-UR, part number 942154002. Preserve the full suffix because L2A, L3A-MR and L3A-UR variants represent different software or routing scope and should not be treated as interchangeable ordering descriptions.
Build the copper and fiber port plan
The saved source lists Ports in total up to 52, Basic unit 4 fixed ports: 4x 1/2.5/10 GE SFP+, Modular: 48x FE/GE ports expandable with four media module slots, 12x FE/GE ports per module. Allocate access, aggregation and high-speed uplink interfaces before requesting supply. Confirm transceiver format, fiber medium, reach, breakout needs, link redundancy and spare capacity for the final topology.

Review rack power and cooling
The manufacturer data gives PSU unit input: 100 - 240 V AC; switch can be operated with either 1 or 2 field-replaceable PSU units (to be ordered separately), an operating reference of 0 to +60 °C °C, and dimensions of 480 mm x 88 mm x 445 mm. Check rack depth, airflow, fan and power redundancy, grounding, branch protection and service clearance against the project cabinet design.
Separate hardware and software scope
State the required switching, routing, redundancy, management, cybersecurity and time-synchronisation functions. Ask the quotation to separate the base hardware, software entitlement, power or fan modules, line cards, transceivers and accessories where they are not included in the requested part number.
Prepare an engineering RFQ
Send HKXY the exact reference Hirschmann DRAGON MACH4000-48G+4X-L3A-UR, part number 942154002, quantity, destination and target delivery date. Add the network diagram, rack elevation, port schedule, power-feed design, environmental conditions and required documentation.
Receipt and lifecycle documentation
Compare the delivered nameplate with the approved purchase line before installation. Retain photographs, module inventory, configuration backup and test results so future maintenance can distinguish the accepted build from nearby DRAGON MACH variants.
