Questions about this item

Can I keep using my 100-Mbps network cards with the SWJ-100A?

Yes, the switch operates at 100 Mbps so existing Fast Ethernet cards connect directly without speed mismatch.

How do I verify the SWJ-100A is routing traffic correctly after connecting the cables?

The manual toggle on the front panel selects the active link; watch the port LEDs to confirm the chosen path is lit and data flows.
