• Supports DIN rail, S7-300 rail, and S7-1500 rail mounting.
• Integrated PROFINET IO device functionality with system redundancy.
• Office features include RSTP, VLAN, IGMP, and more.
• C-PLUG removable storage is included in the scope of supply.
• Layer 3 IP routing is integrated.
• Supply voltage rated at 24 V DC (19.2 ... 28.8 V).
• Power loss rated at 48 W.
• Ambient operating temperature range: -40 ... +70 °C.
• Protection class IP20.

One distinctive capability is the integrated Layer 3 routing, which allows the switch to route IP traffic between different subnets without a separate router, reducing latency and simplifying network design.

Real-World Applications

In a typical automotive assembly plant, the 6GK5408-8GR00-2AM2 can be deployed in a control cabinet to connect multiple PLCs, HMIs, and drives. Its combo ports allow mixing copper connections for nearby devices and fiber links for longer distances or noisy environments. The switch's PROFINET IO device functionality enables seamless integration into Siemens TIA Portal, and its support for MRP and HRP ensures network redundancy to avoid production stoppages.

Installation and Setup

Mount the switch on a 35 mm DIN rail or an S7 mounting rail using the integrated fastening clips. Ensure adequate clearance for air circulation and cable bends. Connect the power supply to the 4-pole terminal block, observing the rated voltage of 24 V DC. For initial configuration, use the dedicated RJ45 management port or the console port (RJ11). The C-PLUG stores the configuration and can be transferred to a replacement unit for quick service.

Maintenance and Reliability

With an MTBF of 28 years, the 6GK5408-8GR00-2AM2 is designed for long-term reliability. Periodically inspect the unit for dust accumulation and ensure the ambient temperature stays within the -40 to +70 °C range. Verify that the signaling contact is wired to an alarm system to detect power failures. The C-PLUG simplifies replacement, reducing downtime.

Solving the Port Density Challenge with the 6GK5408-8GR00-2AM2

This SCALANCE XM408-8C managed switch starts with 8 combo ports, each supporting either 10/100/1000 Mbit/s RJ45 or SFP connections. You can expand it to a maximum of 24 ports using optional extender modules, making it a flexible foundation for both current needs and future growth.

Compatibility and Integration

This switch supports a wide range of protocols, including PROFINET IO, EtherNet/IP, RSTP, MSTP, MRP, and Layer 3 routing protocols like OSPF and VRRP. It can be configured via CLI, web-based management, or STEP 7, and supports SNMP v1/v2/v3 for network management. The switch is also approved for hazardous locations (ATEX, IECEx, Class 1 Div 2) and marine applications (ABS, BV, DNV GL, LRS, NK, PRS, RINA).

Troubleshooting Common Issues

If ports are not linking, verify that the SFP transceivers are compatible and seated correctly. For power issues, check the supply voltage and the fuse (F 15 A / 125 V). If the switch is not appearing on the network, confirm the IP settings via the console port. Use the port diagnostics and statistics functions to isolate faulty cabling or devices.
