Hirschmann MS2108-2 Replacement for MICE Series

Product Overview

Hirschmann MS2108-2 Replacement for MICE Series: Smooth Migration from Legacy Industrial Ethernet Infrastructure

The Hirschmann MS2108-2 is a managed media module designed for the MICE (Modular Industrial Communication Equipment) Series platform — one of the most widely deployed industrial Ethernet switch architectures in process automation, power distribution, and manufacturing environments. As legacy MICE installations approach end-of-life or require capacity expansion, the MS2108-2 serves as both a direct replacement for discontinued slot-in media modules and a validated upgrade path for engineers modernizing their control network infrastructure.

This module supports fiber-optic and copper media conversion within the MICE chassis, enabling seamless integration into existing ring topologies (HiPER-Ring, MRP) without requiring changes to upstream PLC programming or SCADA configurations. Whether you are replacing a failed unit in a Siemens S7-300 or S7-400 networked environment, migrating from older RS2-XX or RS20 unmanaged switches, or expanding an existing MICE chassis to add redundant fiber uplinks, the MS2108-2 provides a plug-compatible solution that minimizes engineering rework and field downtime.

Compatibility Comparison Table

Seamless Upgrade Solutions

A successful MICE platform migration rarely involves a single component. In practice, engineers replacing or expanding a MICE chassis installation will also evaluate adjacent modules and system elements to ensure end-to-end compatibility. The MS2108-2 is commonly deployed alongside the Hirschmann MICE MS2126-4 power supply module, which provides the 24 VDC backplane feed required for all slot-in media modules. For sites running fiber ring topologies, the Hirschmann RS20-0400M2M2SDAEHH or similar RS20-series compact switches are often used as edge nodes feeding into the MICE chassis uplink ports.

Where PROFINET communication is the primary protocol, the MS2108-2 integrates transparently with Siemens S7-300 CP343-1 and S7-400 CP443-1 communication processors — no GSD file changes or hardware configuration updates are required in STEP 7 or TIA Portal when performing a like-for-like module swap. For installations that have migrated to Siemens S7-1500 controllers with CM 1542-1 PROFINET interface modules, the MS2108-2 continues to operate as a transparent Layer 2 switch module, preserving existing IP addressing and device naming.

Sites using Hirschmann SPIDER II unmanaged switches at field level — common in older conveyor, packaging, and press control cabinets — can retain those edge devices while upgrading the backbone MICE chassis with the MS2108-2 to gain managed switching, VLAN segmentation, and SNMP monitoring capabilities. For control cabinets where space is constrained, the slot-in form factor of the MS2108-2 eliminates the need for additional DIN rail space compared to standalone switch alternatives.

If your migration also involves updating the network management layer, the MS2108-2 is fully supported by Hirschmann Industrial HiVision network management software, enabling topology discovery, port-level diagnostics, and firmware updates from a central engineering workstation. For sites requiring signal isolation between fiber and copper segments — particularly in high-EMI environments such as variable frequency drive (VFD) panels or arc furnace control rooms — pairing the MS2108-2 with a dedicated fiber media converter or signal isolator module on the copper side is a recommended best practice.

Retrofit Guidance FAQ

Q: Can I hot-swap the MS2108-2 into a running MICE chassis without shutting down the system?
A: The MICE platform supports module insertion with the chassis powered; however, Hirschmann recommends placing the affected port in a disabled state via Industrial HiVision before physical insertion to prevent transient network events. Ring redundancy (HiPER-Ring/MRP) will maintain network continuity during the swap if properly configured.

Q: Do I need to update PLC programs or PROFINET device configurations after replacing the module?
A: No. The MS2108-2 is a Layer 2 switch module — it is transparent to PROFINET device names, IP addresses, and GSD/GSDML configurations. Your existing TIA Portal, STEP 7, or RSLogix project files require no modification for a direct replacement.

Q: Is the fiber connector type compatible with my existing cabling?
A: The MS2108-2 uses SC-type fiber connectors. Verify your installed fiber patch cables terminate in SC connectors. If your existing infrastructure uses ST or LC connectors, SC adapter sleeves or short patch cable replacements will be required — a minor field change that does not affect backplane or software configuration.

Q: What if my MICE chassis uses an older backplane revision?
A: The MS2108-2 is designed for the standard MICE 8-slot backplane. If your chassis predates the current MICE generation, confirm the backplane revision with the chassis label before ordering. TOPNLMS technical support can assist with compatibility verification based on your chassis serial number.

Q: Can this module support both single-mode and multi-mode fiber?
A: The MS2108-2 variant designation specifies the fiber type. The “-2” suffix typically denotes multi-mode fiber (MM, 50/125 µm or 62.5/125 µm). If your installation uses single-mode fiber (SM, 9/125 µm), confirm the exact variant required before ordering. TOPNLMS stocks multiple MICE media module variants to match your fiber plant.

Warranty Assurance

Every Hirschmann MS2108-2 unit shipped by TOPNLMS is covered by a 12-month replacement warranty from the date of delivery. Prior to dispatch, each module undergoes functional verification including power-on self-test, port link-up confirmation, and backplane interface check. Units are packed in anti-static ESD-safe packaging with foam cushioning to prevent transit damage.

In the event of a warranty claim, TOPNLMS provides advance replacement support — a replacement unit is dispatched before the defective module is returned, minimizing production downtime for critical installations. Our standard lead time for in-stock units is 3–7 business days for international shipments from Xiamen, China, with DHL Express and FedEx International Priority available for urgent requirements.

For procurement teams requiring documentation, TOPNLMS can provide a test report, packing list, and commercial invoice with HS code declaration for customs clearance. Volume pricing is available for orders of 3 or more units. Contact our technical sales team to discuss blanket order arrangements for MRO (Maintenance, Repair & Operations) stocking programs.
