The RB493 has nine ethernet ports and three miniPCI slots, it also has a switch chip, so the ethernet ports 2-9 can be grouped together to make it act as a switch.
RB493 includes RouterOS - the operating system, which will turn this powerful system into a highly sophisticated router, firewall or bandwidth manager.
The RB493AH model includes the higher speed Atheros 680MHz CPU, more memory, and a Level5 license for more simultaneous tunnel interfaces and hotspot users.

- All tests are done with Xena Networks specialized test equipment (XenaBay),and done according to RFC2544 (Xena2544)
- Max throughput is determined with 30+ second attempts with 0,1% packet loss tolerance in 64, 512, 1518 byte packet sizes
- Values in Italic indicate that max throughput was reached without maxing out CPU, but because board interface configuration was maxed out
- Test results show device maximum performance, and are reached using mentioned hardware and software configuration, different configurations most likely will result in lower results
