Industrial 3G HSPA+ router with VPN, firewall and NAT for remote Ethernet automation networks

SCALANCE M874-3 connects Ethernet devices over cellular HSPA+ and combines a two-port switch with routing, VPN, firewall, NAT, digital input and digital output functions. Cellular service, antenna design and the complete security configuration must be verified before deployment.

Cellular service and VPN checkConfirm regional 3G service and approvals, SIM card, APN, antenna and signal path, 24 V supply, Ethernet addressing, firewall and NAT rules, VPN certificates and remote-management settings. Siemens lists this model as discontinued.

Description

6GK5874-3AA00-2AA2 is the SCALANCE M874-3 industrial mobile router for connecting Ethernet automation equipment through GSM and UMTS HSPA+ networks. It provides two 10/100 Mbit/s RJ45 ports, one digital input, one digital output and security functions for controlled remote access.

Before replacement, export the router configuration and preserve SIM, APN, IP, NAT, firewall, VPN, user and certificate information. Confirm that the destination country and mobile operator still support the required 3G bands and service before planning a like-for-like exchange.

Cellular Integration

Network service, SIM provisioning and the complete antenna path determine whether the router can register reliably.

Service check

Confirm supported 3G bands, destination-country approval and ongoing operator service before shipment.

SIM and APN

Record SIM format, PIN policy, APN, credentials, roaming limits and expected public or private addressing.

Antenna path

Verify SMA connection, 50-ohm antenna system, cable loss, lightning protection and safe clearance.

FAQ

How can I confirm that 6GK5874-3AA00-2AA2 will operate in the destination country?

Check the local approvals, supported GSM and UMTS bands and whether the mobile operator still provides compatible 3G service. Confirm SIM, APN, roaming and antenna requirements before dispatch because the model is discontinued.

What settings should be saved before replacing 6GK5874-3AA00-2AA2?

Export the router configuration and preserve APN, SIM policy, Ethernet addresses, routes, NAT and firewall rules, VPN profiles, certificates, users, digital I/O settings and a copy of relevant logs.

Why can 6GK5874-3AA00-2AA2 detect the SIM but fail to establish a data session?

Verify SIM activation and PIN, APN and credentials, roaming permission, cellular bands, antenna connection and signal quality. Review mobile-network and system logs before changing the VPN configuration.

How should the antenna for 6GK5874-3AA00-2AA2 be installed?

Use a compatible 50-ohm antenna on the SMA connector, minimize cable loss and follow the required user clearance. For outdoor antennas, implement the full site lightning-protection and grounding concept rather than relying only on an inline protector.

What should be checked when the VPN on 6GK5874-3AA00-2AA2 remains down?

First confirm cellular registration and IP connectivity, then check device time, peer reachability, certificates or keys, authentication, tunnel proposal, routes and firewall rules. Compare both endpoints and retain the failure log.

How should 6GK5874-3AA00-2AA2 be commissioned after replacement?

Install and ground the router, connect the approved antenna and SIM, restore the reviewed configuration on an isolated path and verify cellular registration. Then test VPN, NAT, required application traffic, alarm I/O and blocked traffic before production release.
