The Cisco NCS-57B1-6D24H-S is a fixed 1RU router from the Cisco Network Convergence System (NCS) 5700 Series. Specifically, it combines 4.8 Tbps of 400GE/100GE forwarding capacity with 30 QSFP-DD ports. As a result, it serves aggregation, distributed core, and peering roles in a compact, power-efficient package.

6x 400G and 24x 100G QSFP-DD Ports

In addition, the router provides six 400G QSFP-DD ports and twenty-four 100G QSFP-DD ports. Consequently, operators can mix 400G core uplinks with dense 100G service ports in a single rack unit. Moreover, every port accepts QSFP28 optics, and an optional QSA adapter adds SFP+ support.

400G ZR/ZR+ for Routed Optical Networking

Furthermore, the six 400G ports and the top row of twelve 100G ports support coherent ZR and ZR+ optics. Therefore, operators can connect routers directly over DWDM links without separate transponders. Likewise, the 400G ports support breakout, although breakout disables the lower row of 100G ports.

Security, Timing, and Control Plane

Also, the router delivers full line-rate MACsec encryption, Class C IEEE 1588 PTP, and Synchronous Ethernet, with GNSS, 10 MHz, and ToD timing ports. For this reason, it suits mobile transport and 5G networks that need precise timing. In addition, an 8-core 2.0 GHz x86 CPU with 32GB of memory and a 128GB SSD runs 64-bit Cisco IOS XR.

Perpetual Licensing (H-S) vs. Flexible Consumption (-SYS)

The NCS-57B1-6D24H-S uses Cisco’s perpetual licensing model. By comparison, the NCS-57B1-6D24-SYS shares the same hardware but uses the Flexible Consumption Model with Smart Licensing. Meanwhile, the NCS-57B1-5D24H-SE (SE variant) offers five 400G ports with higher scale.

Redundancy and Hardware

Finally, the NCS-57B1-6D24H-S uses two 2000W power supplies in 1+1 redundancy, in either AC or DC versions, plus a redundant fan tray. As a result, it keeps running through a single power or fan failure.

Key Features

• First, it provides 6x 400G and 24x 100G QSFP-DD ports in 1RU.
• Second, it delivers 4.8 Tbps of forwarding capacity.
• Additionally, it supports 400G ZR/ZR+ coherent optics.
• Furthermore, it offers full line-rate MACsec encryption.
• Moreover, it supports Class C PTP, SyncE, and GNSS timing.
• Finally, it uses perpetual licensing rather than a consumption model.

Why Lease from Telecom Leasing?

• First, you deploy 400G routing without a large capital outlay.
• Second, we test every unit so it’s ready to deploy.
• In addition, flexible terms cover spares, upgrades, and project builds.
• Finally, you get fast quotes and quick shipping.

Best of all, Telecom Leasing offers the NCS-57B1-6D24H-S for lease or purchase, so you can build 400G aggregation at a fraction of new cost.

Frequently Asked Questions

What is the Cisco NCS-57B1-6D24H-S?

In short, it’s a 1RU Cisco NCS 5700 Series router with 6x 400G and 24x 100G QSFP-DD ports, 4.8 Tbps of forwarding, and perpetual licensing.

What’s the difference between the NCS-57B1-6D24H-S and NCS-57B1-6D24-SYS?

Both share the same hardware and ports. However, the H-S uses perpetual licensing, while the -SYS uses Cisco’s Flexible Consumption Model.

Does the NCS-57B1-6D24H-S support 400G ZR and ZR+ optics?

Yes. In fact, all six 400G ports and the top row of twelve 100G ports support ZR and ZR+ coherent optics.
