RS20 M2 T1 switch: configuration change guide
RS20-0800M2T1TDAUHH is the complete Hirschmann designation for an eight-port system combining multimode SC and RJ45 uplinks. This newly written RS20 M2 T1 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.
Fiber And Copper Roles
Combining fiber and copper uplinks can reduce external media converters in a compact control cabinet. The requested unit belongs to the Hirschmann RS20 fiber-and-copper family and is a fanless managed Fast Ethernet DIN-rail switch with one multimode SC uplink and one RJ45 uplink position. The visible M2 and T1 codes combine a multimode 100BASE-FX SC interface with a 10 or 100 Mbit/s twisted-pair RJ45 interface.
Test the M2 optical route and T1 copper route independently. Therefore, one cable fault cannot be mistaken for a switch problem. Copper noise and fiber attenuation require different troubleshooting methods. These records support both troubleshooting and a technically useful quotation.
Separate Media Evidence
Review local port schedule, M2 fiber path, T1 copper destination, SC connector, cable test, speed, power, temperature code, software, and lifecycle. Keep RS20-0800M2T1TDAUHH unchanged in the RFQ. One suffix difference can affect the software, environmental class, approval set, or customer-specific construction.

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.
RS20 M2 T1 switch Mixed-Link 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.
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.

These nearby configurations can support spare and migration planning, but they are not direct substitutes. Check port count, connector style, fiber mode, optical reach, software level, temperature code, approvals, and the full suffix.
