Siemens 6GK5534-5TR00-2AR3 SCALANCE XR502-32 Layer 3 Switch, 24V DC, 8x SFP+ 10G

The Siemens SCALANCE XR502-32 (6GK5534-5TR00-2AR3) is a 19-inch rack, Layer 3 managed Ethernet switch with 2x combo 1G/2.5G/5G/10G RJ45 ports, 24x SFP ports, and 8x SFP+ ports for 10 Gbit/s uplinks. It runs from a single 24V DC supply, supports installation up to 4000m altitude, and integrates a redundancy manager for ring topologies.

Selection Notes

The 2AR3 variant is the DC-only version: a single 24V DC input with a spare terminal block for a second, redundant 24V feed - the option to pick when the cabinet already runs on a 24V DC bus. Pick the 3AR3 sibling instead for AC mains supply. With 24 SFP slots and only 2 RJ45 uplink ports, the XR502-32 is built for fiber-heavy access layers rather than copper-dense ones - use the XR526-8 or XR522-12 instead where most drops are RJ45.

Applications

The 24x SFP port count fits distribution cabinets aggregating long-haul fiber runs from multiple remote panels or rings, with the 8x SFP+ ports carrying the 10 Gbit/s uplink back to the plant core.
