The specs that decide what you can run, straight from the manufacturer's data sheet.
- 014x 100G QSFP28Four 100G ports link up to four workstations or servers directly at full speed.
- 02Breakout to 16x 25GEach port splits into 4x 25G with breakout cables, so the switch can serve up to 16 25G devices.
- 03394.9 Gbps Layer 2Non-blocking throughput means all four 100G ports can run at once without contention.
- 04AC or DC dual PSU slotsHot-swap slots take 100-240 V AC or 36-57 V DC supplies for redundancy in a lab or rack.
In practice
Built for the work.
Use case
Entry-level 100G for small AI teams
Connect two to four GPU workstations or servers over 100G to share datasets and move checkpoints between machines quickly. At 41 W max and with rack, wall or desk mounting, it fits a small office lab as easily as a server rack.
Integration
Rack, wall or desk mount, AC or DC
Interfaces are 4x 100G QSFP28 plus a 10/100 Ethernet management port, switched by a Marvell 98DX4310 chip running RouterOS v7. Dual hot-swap PSU slots take 100-240 V AC or 36-57 V DC. The 320 x 185 x 44 mm chassis draws 41 W max and has 2 fans.
