The SCALANCE XB008 is a fixed-configuration unmanaged industrial Ethernet switch from Siemens, positioned in the XB unmanaged switch family. The part number prefix indicates the unmanaged XB series (6GK5‑008‑0…).
Engineering Verification Checklist
- Confirm supply voltage matches branch design (record lists no voltage spec — check project documentation)
- Verify RJ45 connector polarity and termination standard for each port segment
- Check DIN rail clearance for side-by-side XB008 installation if multiple units are needed
- Validate that enclosure IP20 rating is adequate for the intended mounting environment
- Confirm operating temperature range covers the expected ambient at installation point
- Verify wall-mount option spacing matches mounting surface preparation
- Ensure cable bend radius clearances are met at all eight ports during routing
- Confirm compatibility of end devices with 10/100 Mb/s auto-negotiation on all ports

Why the alternates share family proximity
XB008G (6GK50080GA101AB2): Shares the same eight RJ45 port count and fixed unmanaged architecture. The difference is package style (Box vs Bulk). No change to port count or speed class.
XB005 and XB005G (6GK50050GA101AB2, 6GK50050BA001AB2): Reduce the copper port count from eight to five while preserving DIN rail mounting and IP20 rating. XB005G introduces gigabit capability on copper; the seed does not list this.
XB004 variants (6GK50042BD001AB2, 6GK50041BF001AB2, 6GK50041GL101AB2, 6GK50041GM101AB2): Shift to four copper ports plus one or two fiber uplink ports using SC connectors. These are not eight-port variants and differ in port media.
FAQ
Can the SCALANCE XB008 be mounted on a standard 35 mm DIN rail in a control cabinet? Yes, the record lists DIN rail mounting as a supported option alongside wall mounting.
Does the XB008 support auto-negotiation between 10 Mb/s and 100 Mb/s devices? The copper type field lists 10/100 Mb/s, indicating speed auto-negotiation is a characteristic of the port design.
What is the operating temperature limit for this switch? The switch is rated for operation from 10°C up to 60°C according to the catalog record.
