Q
What are S12700 Series Switch line cards?
A
S12700 Series Switch line cards are modular hardware units that plug into S12700 chassis to deliver high-density Ethernet, OTN and MPLS switching capabilities.
Q
Which port densities do S12700 line cards support?
A
S12700 line cards support port densities from 10GE to 400GE per slot, enabling flexible scaling from small to ultra-high-throughput environments.
Q
How do I choose the right line card for my network?
A
Select based on required port type (SFP/SFP+/QSFP+/QSFP28), bandwidth capacity, and feature set such as OTN, MPLS, or EVPN-VXLAN.
Q
Are S12700 line cards hot-swappable?
A
Yes. S12700 line cards support hot-swap capability, allowing installation or replacement without powering down the chassis.
Q
What is the maximum throughput per S12700 line card slot?
A
Each slot delivers up to 1.6 Tbps of switching capacity, supporting line-rate forwarding under full load.
Q
Do S12700 line cards require additional licensing?
A
Advanced features like MPLS-TP, EVPN-VXLAN and BGP-EVPN may require software licenses that can be activated per chassis or chassis cluster.
Q
How is power consumption managed on S12700 line cards?
A
Power is allocated dynamically across slots, with per-card consumption profiles documented in the datasheet for efficient planning.
Q
Can S12700 line cards be mixed in one chassis?
A
Yes. You can install line cards of different port speeds and features in the same chassis, respecting power and cooling requirements.
Q
What redundancy features do S12700 line cards support?
A
They support control-plane and data-plane redundancy, including dual-supervisor engines and bidirectional forwarding detection (BFD).
Q
How do I monitor S12700 line card performance?
A
Use the built-in CLI, SNMP, NetStream or third-party NMS integration to track throughput, error statistics, and port status.
Q
Are S12700 line cards compatible with virtualization features?
A
Yes. They fully support Huawei VRP-powered virtualization, including EVPN, VFI and multi-tenant QinQ.
Q
What environmental specifications apply to these line cards?
A
Line cards operate between 0°C to 45°C (32°F to 113°F) and 10%–90% non-condensing humidity, per chassis environmental guidelines.
Q
How do I upgrade firmware on S12700 line cards?
A
Use the VRP TFTP/FTP upgrade commands or iMaster NCE-View for centralized, non-disruptive software updates.
Q
What warranties and support are available?
A
Huawei provides a standard five-year warranty and offers optional Huawei SMARTCare support contracts for accelerated RMA and 24×7 technical assistance.
Q
Can I mix OTN and Ethernet line cards in S12700?
A
Yes. The chassis supports simultaneous deployment of OTN and Ethernet line cards for unified packet and optical transport.
Q
What migration strategies exist for legacy switches to S12700?
A
Use hot-swap line card installation, VLAN/QoS rule consistency, and dual-homing designs to ensure seamless cutover with minimal downtime.
