Q
What are the key features of Huawei S7700 Series Switch line cards?
A
S7700 line cards deliver high port density, line-rate forwarding, hot-swappable design, VXLAN EVPN support, advanced QoS/security, and unified eSight management for campus and data-center deployments.
Q
How do I choose the right S7700 line card for my network requirements?
A
Select an S7700 line card based on required port speed (10/40/100 GbE), port count, power budget, backplane bandwidth, and feature support (VXLAN, MPLS, QoS), ensuring chassis compatibility.
Q
What port densities and speeds are available on S7700 Series Switch line cards?
A
S7700 line cards offer up to 48×10 GbE SFP+, 16×40 GbE QSFP+, 8×100 GbE QSFP28, and mixed-speed modules, enabling flexible aggregation and spine-leaf architectures.
Q
Are Huawei S7700 Series line cards hot-swappable?
A
Yes. All S7700 line cards support hot-swap without traffic interruption. Insert or remove modules safely while the chassis remains powered and forwarding traffic.
Q
How do I install an S7700 Series Switch line card?
A
Power off or disable the slot, slide the line card into an empty S7700 slot until it clicks, tighten front screws, then power on or enable the slot. Verify status via LED and CLI.
Q
What is the typical power consumption of S7700 line cards?
A
Power consumption varies by model: 48×10 GbE cards draw ~70 W, 16×40 GbE ~150 W, 8×100 GbE ~250 W. Refer to the datasheet for precise power budgets per module.
Q
How do S7700 Series line cards support network resiliency?
A
They support link aggregation (LACP), MLAG, VRRP-A, graceful restart, and multi-chassis trunking to ensure path redundancy and sub-50 ms failover.
Q
Which management and monitoring interfaces do S7700 line cards support?
A
S7700 line cards offer CLI (console, SSH), SNMP v2/v3, NetConf/YANG, OpenFlow, NetStream telemetry, and Huawei eSight integration for centralized management.
Q
Can I mix different S7700 line card models in the same chassis?
A
Yes. You can combine 10 GbE, 40 GbE, and 100 GbE cards in one S7700 chassis as long as total backplane and power budgets are not exceeded.
Q
What environmental conditions do S7700 line cards require?
A
Operating temperature: 0–45 °C; storage: –40–70 °C; humidity: 5–95% non-condensing; altitude: up to 5,000 m with derating above 2,000 m per Huawei guidelines.
Q
How do I troubleshoot a failed S7700 Series Switch line card?
A
Check module LEDs, run ‘display device’ and ‘display module’ CLI commands, review alarm logs, reseat the card, verify backplane connectivity, and replace if hardware faults persist.
Q
What is the maximum forwarding capacity per S7700 line card?
A
Depending on the model, each line card delivers up to 4.8 Tbps backplane capacity and supports wire-speed forwarding on all ports simultaneously.
Q
Are S7700 Series Switch line cards compatible with other Huawei chassis?
A
No. S7700 line cards are designed exclusively for the S7700 chassis family and are not supported in S9300, S9700, or other series.
Q
How do S7700 line cards enhance QoS and security?
A
They provide 8-level hardware queues, traffic policing, shaping, hierarchical scheduling, ACLs, port security, DHCP snooping, and IP source guard for comprehensive traffic control.
Q
What warranty and support options are available for S7700 line cards?
A
Huawei offers a 5-year limited hardware warranty, optional SMARTCARE services for on-site support, software updates, and 24×7 technical assistance.
Q
How do I upgrade firmware on an S7700 Series Switch line card?
A
Use the system upgrade command in CLI (system upgrade file flash://<package> force) or eSight to distribute the firmware package, then reboot the card to apply updates.
Q
How do S7700 Series line cards integrate with SDN and automation tools?
A
They support OpenFlow 1.3, NetConf/YANG APIs, RESTful interfaces, and integrate with Huawei CloudFabric and third-party controllers for programmable network automation.
