RS20 SDAUHH fiber switch: configuration change guide
RS20-0800M2M2SDAUHH is the complete Hirschmann designation for an eight-port multimode SC replacement for a standard Hirschmann configuration. This newly written RS20 SDAUHH fiber switch article gives engineers and buyers a model-specific reference for interface planning, change evidence, lifecycle review, and sourcing.
Keep every character of the code in drawings and purchase requests. A family name helps discovery, but it cannot confirm the exact ports, connectors, software, environmental options, or revision.
Lifecycle And Successor Review
Belden currently marks the RS20, RS30, and RS40 configurator as Limited Availability or Passive and points users toward BOBCAT replacement options. Therefore, exact-code stock and lead time need a fresh check. A successor also needs engineering review for interfaces, mounting, power, software, security, and configuration migration.
Prepared Multimode Spare
A standard Hirschmann suffix is useful for installed-base consistency when maintenance teams keep matching shelf spares. The requested unit belongs to the Hirschmann RS20 multimode SC family and is a fanless managed Fast Ethernet DIN-rail switch with two multimode SC optical uplinks. On standard 0800 M2M2 variants, six local 10 or 100 Mbit/s RJ45 ports are paired with two 100BASE-FX multimode SC uplinks.
Load the stored configuration on a bench spare. Then verify alarms, management access, and optical links before warehouse storage. An untested shelf spare can still delay recovery through old firmware or missing configuration. These records support both troubleshooting and a technically useful quotation.

Bench And Storage Record
Review eight-port map, two M2 optical routes, multimode fiber grade, SC condition, link loss, power, software level, temperature code, approvals, and full suffix. Keep RS20-0800M2M2SDAUHH unchanged in the RFQ. One suffix difference can affect the software, environmental class, approval set, or customer-specific construction.

Quotation And Delivery Inputs
Send HKXY Instruments the quantity, destination, required date, old label, network drawing, and acceptable alternative policy. We can review availability, current price, lead time, export packing, and delivery options. Compare the result with the official Belden Hirschmann RS20 configurator.
RS20 SDAUHH fiber switch Spare Acceptance
Run acceptance in stages. First, verify power, mounting, and startup. Next, test each copper and optical path separately. Then restore management, VLAN, alarms, and redundancy functions. Finally, save the accepted configuration and link measurements with the site change record.
