Description

Ultra‑dense 400G line card for 8800-series modular chassis, providing 36x400G QSFP56‑DD ports for high-capacity spine and core aggregation. Supports 4x100G breakout on qualified optics to ease migration from 100G to 400G. Ideal for large-scale fabrics requiring maximum throughput per slot with operational simplicity.

Features

- Maximizes 400G density with 36 QSFP56‑DD ports
- Supports 4x100G breakout for phased migrations
- Hot-swappable for serviceability
- Engineered for high-scale spine/core fabrics
- Standards-based 400GbE interoperability

FAQs

Q: Can I break out 400G ports to 4x100G?
A: Yes, on supported QSFP56‑DD optics/DACs and with platform software that enables breakout profiles.

Q: Which transceivers are supported?
A: QSFP56‑DD 400G optics/DACs/AOCs. For 100G operation, use eligible 4x100G breakout optics or cables as listed in the platform’s compatibility matrix.

Q: Is any special license required to enable ports?
A: Port activation generally follows chassis and software licensing. The line card itself typically does not require separate per-port licensing.

Q: What environments is this card best suited for?
A: High-throughput spine, core, and aggregation layers where maximum 400G density per slot is needed.

Q: Will it work in any slot of my 8800 chassis?
A: Use in supported slots only; check the chassis hardware guide for slot compatibility and supervisor requirements.
