![MikroTik RB493G | Router | 9x RJ45 100Mb/s, 3x miniPCI, 1x USB Ilość portów LAN9x [10/100M (RJ45)]](https://www.batna24.com/img2/500/682_1.webp?20989284221)
RB493G has nine Gigabit Ethernet ports, three miniPCI sockets and two switching circuits, so the Ethernet ports can be combined into two groups of switches to provide bandwidth. RB493G also has a USB 2.0 port and microSD card slot for adding more storage or 3G USB 3G for backup connection.
The device has a powerful Atheros AR7161 processor and has 256 MB of built-in RAM. RB493G contains RouterOS - an operating system that will turn this powerful system into a highly advanced router, firewall or bandwidth manager.

If you have not turned off the router, the filesystem has not been unmounted properly. During startup, RouterOS will perform a filesystem test. Depending on the size of your hard drive, this may take several minutes. Do not interrupt the file system test!
User name is 'admin' and there is no password (press 'Enter'). To change password use '/password' command.
RouterBOARD is a hardware platform from MikroTik, which is a line of routers with RouterOS operating system. Almost all models of RouterBOARD devices can be powered via Ethernet (PoE) and have a connector for external power source.
