  • Fanless metal chassis ensures silent operation
  • Dual boot between RouterOS and SwOS for flexible control

Compact 10G SFP+ Switch

The PISKEKAT CRS305-1G-4S+IN is a new desktop switch with four SFP+ ports delivering up to 10 Gbit per port and a single Gigabit copper port for management. It runs an 800 MHz CPU with 512 MB RAM and 16 MB storage inside a fanless metal chassis measuring 141 x 115 x 28 mm. Dual DC jacks provide power redundancy and the unit accepts 802.3 af/at PoE input.

Suits fibre uplinks not copper density

This switch suits builders who need a small, silent aggregation point for four 10G fibre links and a management port. It does not suit buyers who want multiple copper 10G ports, PoE output for access points or cameras, or a larger port count for rackmount deployments. The dual-boot choice between RouterOS and SwOS fits administrators who want either full Layer 3 routing or a simplified switch-only interface.

Four 10G ports with routing headroom

The four SFP+ ports comfortably handle 10 Gbit line-rate traffic for uplinks or server links while the CPU and RAM provide headroom for RouterOS routing features such as VLANs and ACLs. The single Gigabit management port and 16 MB storage limit the device to configuration duties rather than high-volume logging or proxy services. Fanless operation means thermal limits are reached only in extreme ambient temperatures.

Highlights

  • Four 10 Gbit SFP+ ports for high-speed fibre uplinks
  • Single 1 Gbit copper port provides management access
  • Dual DC jacks give power redundancy
  • Fanless metal chassis ensures silent operation
  • Dual boot between RouterOS and SwOS for flexible control

Questions about this item

What type of power supply is required for the two DC jacks on this CRS305 switch?

The switch accepts 802.3 af/at PoE input through its SFP+ ports or can be powered via the two DC jacks for redundant power supply.

Will the 1 Gbit copper management port limit throughput when connecting older 1 Gbit servers to the 10 Gbit SFP+ ports?

The management port is separate from the four 10 Gbit SFP+ ports, so older 1 Gbit devices connect at their native speed without affecting the 10 Gbit uplinks.

How can I verify the CRS305 is running the correct operating system after initial setup?

Check the boot selection in RouterBOOT loader settings or the running interface — SwOS provides a switch-only dashboard while RouterOS exposes routing and Layer 3 menus.
