A
The S9700 chassis supports up to six full-height line cards in a 19-slot frame or four line cards in a 14-slot compact frame, allowing flexible scaling of port density.
Q
Are S9700 Series line cards hot-swappable?
A
Yes. S9700 line cards are fully hot-swappable, enabling live insertion or removal without interrupting switch operation or traffic forwarding.
Q
What uplink interface types are supported on S9700 line cards?
A
Depending on the model, S9700 line cards offer SFP+, QSFP+, or CFP2 interfaces for uplinks, supporting 10 GbE, 40 GbE, and 100 GbE connectivity respectively.
Q
What is the typical power consumption of an S9700 line card?
A
Power consumption per line card ranges from 150 W (48×10 GbE) to 300 W (16×100 GbE), subject to traffic load and port utilization.
Q
Which OS versions are compatible with S9700 line cards?
A
S9700 line cards require Huawei VRP (Versatile Routing Platform) version V100R005C00 or later to ensure full feature support and stability.
Q
What key performance features do S9700 line cards offer?
A
S9700 line cards provide hardware-based QoS, large and dynamic packet buffers, advanced ACLs, and traffic monitoring (sFlow/NetStream) for deterministic performance.
Q
Do S9700 line cards support network virtualization?
A
Yes. They support VXLAN, NVGRE, and VRF-lite for network segmentation, enabling multi-tenant data center and cloud deployments.
Q
Can S9700 line cards handle MPLS traffic?
A
S9700 line cards fully support MPLS L2/L3 VPNs, MPLS TE, and Segment Routing, delivering carrier-grade forwarding and programmability.
Q
What redundancy and high-availability features are available?
A
Features include dual control-plane redundancy, Graceful Insertion and Removal (GIR), Bidirectional Forwarding Detection (BFD), and MLAG for zero-packet loss failover.
Q
What environmental conditions do S9700 line cards require?
A
Line cards operate at 0–45 °C, 5–95% relative humidity (non-condensing), and 500–1,096 hPa altitude, conforming to NEBS and ETSI standards.
Q
How do I choose the right S9700 line card for my network?
A
Select based on required port speeds, density, uplink bandwidth, and feature needs—10 GbE for access layers, 40/100 GbE for spine or core aggregation.
Q
What warranty and support options are available for S9700 line cards?
A
Huawei provides a limited lifetime warranty with 8×5 NBD hardware replacement and optional software support packages including updates, patches, and 24×7 technical assistance.
Q
Where can I purchase genuine S9700 Series line cards?
