CRS504-4XQ-IN: bring 100G to everyday networks

Our 100 Gigabit lineup keeps growing—after the CCR2216 router, here comes the matching switch: CRS504-4XQ-IN. It’s compact, sips power (~25 W without attachments), and makes stepping up to 100G practical outside of data centers—perfect for upgrading 10G/25G environments at offices, labs, and studios.

Flexible high-speed optics

• 4 × 100G QSFP28 ports
  • Direct 100G links to other 100G devices
  • Or use breakout cables: each port splits into 4 × 25G, for up to 16 × 25G connections total
• Mix and match per port: 100G, 40G, 4×25G, even 10G/1G—the Marvell DX4310 switch chip handles it with ease.
• Dedicated Ethernet management port included.

Proven in real science

We’ve run this switch in our Genomics Data Network—a high-capacity backbone for researchers working on cutting-edge cancer treatments, where massive genome datasets demand extreme throughput. With these devices, Latvia became the first Baltic country to connect at 100G to the pan-European research network.

Practical by design

Multiple power input options and wall-mount capability keep admins happy, whether it’s a tidy closet, a lab bench, or a field deployment.

CRS504-4XQ-IN—small, efficient, and ready to bring 100G performance to your everyday setup.
