MikroTik CRS305-1G-4S IN Five-port desktop switch with one Gigabit Ethernet port and four SFP 10Gbp

The CRS305 is a compact yet very powerful switch, featuring four SFP ports, for up to 10 Gbit per port. The device has a 1 Gbit copper ethernet port for management access and two DC jacks for power redundancy. The device is a very sleek and compact metallic case without any fans, for silent operation.   The device has a “Dual boot” feature that allows you to choose between two operating systems – RouterOS or SwOS. If you prefer to have a simplified operating system with only switch specific features, use SwOS. If you would like the ability to use routing and other Layer 3 features in your CRS, use RouterOS. You can select the desired operating system from RouterOS, from SwOS or from the RouterBOOT loader settings. All the feature set comes with a disruptive price, providing the best price/performance on the market.     Specifications Details Product code CRS305-1G-4S IN Architecture ARM 32bit CPU 98DX3236 CPU core count 1 CPU nominal frequency 800 MHz Dimensions 141 x 115 x 28 mm License level 5 Operating System RouterOS / SwitchOS Size of RAM 512 MB Storage size 16 MB Storage type FLASH Tested ambient temperature -40°C to 70°C Powering Details PoE in 802.3af/at PoE in input Voltage 12-57 V Number of DC inputs 3 (PoE-IN, DC jack) DC jack input Voltage 12-57 V Max power consumption 18 W Max power consumption without attachments 10 W Ethernet Details 10/100/1000 Ethernet ports 1 Fiber Details SFP ports 4 Other Details CPU temperature monitor Yes Certification & Approvals Details Certification CE/RED, EAC, ROHS
