Siemens 6GK5408-0GA00-8AP2 SCALANCE PE408 Port Extender

Siemens 6GK5408-0GA00-8AP2 is a PE408 port extender for compatible SCALANCE XM-400 managed modular industrial Ethernet switches. It expands the host switch with eight RJ45 ports supporting 10, 100 or 1000 Mbit/s connections. The module supports structured copper network expansion where additional device connections are required within the documented SCALANCE architecture. Siemens reports a PLM discontinuation date of 2025-10-01 and provides replacement guidance through its support system. Procurement should verify the full suffix, host switch compatibility, available expansion position, port requirements and installed network design.
