 The switch supports dual boot of RouterOS and SwOS, so it can do L3 processing to some extent. Having said that, the processes which aren't handled by the chip are processed by CPU, and what is worse, an internal bandwidth between them is only 1Gbps. Therefore, we had better use it as plain L2 switch, or should keep lightweight L3 usage such as connecting to WAN with simple packet filtering. Otherwise its valuable performance will be completely dead. Fortunately it has enough 10GbE ports, so I think fit to pass on the L3 processes to a dedicated router with a LAG. AT-x510-28GTX which is a L3 switch I got some time ago will have tears of joy for this application. The switch supports dual boot of RouterOS and SwOS, so it can do L3 processing to some extent.

 +Following table shows rough power consumptions:
 +
 +^  Situation  ^  Power Consumption  ^
 +| Idle（No SFP modules) |  13W |
 +| Idle（Two 40GBASE-SR4 modules link up） |  15～16W |
 +| Run iperf with 40GBASE-SR4 interfaces |  17W |

 +Cooling fans were pretty noisy in factory default RouterOS version. I updated it to version 6.45.4, now they get quieter than before. The OS aggressively controls their speed between zero to full blast depending on the internal temperature. I think these specs are very kindly for common home use. Thank you, MikroTik. Well, when the fans is running, they cause a certain level of noise. It seems themselves' operating noise is louder rather than wind noise. It is acceptable for me, but not for someone, I guess.
