Compact 10G SFP+ Switch

The CRS305-1G-4S is a five-port desktop switch built around four SFP+ cages running at up to 10 Gbit per port. A single 1 Gbit copper Ethernet port provides management access. The fanless metal enclosure keeps operation silent.

Dual-Boot Layer 2 and Layer 3

RouterOS and SwOS both ship on the device so you can pick a pure switching stack or enable routing and other Layer 3 features without extra licences. The choice is selectable from either OS or the bootloader. Two DC jacks give redundant power input.

Limits of the SFP+ Uplink Design

Throughput tops out at the 10 Gbit line rate of each SFP+ port, so aggregated traffic above that must be shaped or split. The management port stays at 1 Gbit and does not participate in high-speed forwarding. The 800 MHz CPU handles control-plane tasks but is not a data-plane accelerator.

Questions about this item

What are the exact dimensions of the CRS305-1G-4S so I can check it fits my rack shelf?

The switch measures 5.51 inches long, 4.53 inches wide and .98 inches high, weighing .5 kilograms.

How do I power the CRS305-1G-4S and what is the common mistake to avoid?

Connect either of the two DC jacks for power; the common mistake is assuming Power over Ethernet is supported on the 1GbE port, which it is not.

Which replaceable parts or maintenance items will the CRS305-1G-4S need over time?

The fanless metal enclosure has no moving parts to replace; only the external power adapters plugged into the dual DC jacks may need replacement if they fail.
