CRS520-4XS-16XQ-RM: future-proof 100G density with real CPU muscle

Step into the next era of networking with the CRS520-4XS-16XQ-RM—extra processing headroom, 4 GB DDR4 RAM, and the best price per 100G port we’ve seen yet.

Port layout that replaces whole stacks

• 16 × 100G QSFP28
• 4 × 25G SFP28
• 2 × 10G Ethernet (extra convenience for edge or management)

From complex enterprise cores and data centers to media studios and HPC labs, one CRS520 can do the work you’d usually split across multiple boxes.

Why so much CPU on a switch?

Powered by a familiar quad-core ARM at 2 GHz (yes, the one CCR users love), and for good reason:

1. More than a switch. Run OSPF/BGP, out-of-band / management VPNs, ACLs, Jumbo frames, and even L3 hardware-offloaded routing—on the same platform.
2. Built for tomorrow. As Marvell keeps expanding their stellar switch-chip feature set, our software team keeps unlocking new hardware-offloaded capabilities. Expect updates that push CRS520 even further—no paywalls, no subscriptions.

Redundancy & power options

• Two hot-swap PSUs included
• Four hot-swap fans for reliable cooling
• Optional telecom input: supports the PW48V-12V150W Hot Swap −48V DC PSU (sold separately)

CRS520-4XS-16XQ-RM—dense 100G, serious control-plane horsepower, and a roadmap that grows with you.
