​​Frequently Asked Questions​​

​​Q: Can the IE-4000-8GT8GP4G-E support 5G cellular backhaul?​​
A: Yes. Its 10G SFP+ uplinks can aggregate data from 5G small cells or private LTE networks.

​​Q: Is the switch compatible with Cisco DNA Center?​​
A: Limited. While it runs IOS-XE, full DNA Center integration requires additional licenses and is not optimized for OT environments.

​​Q: How to mitigate latency in real-time control systems?​​
A: Enable ​​TSN queuing policies​​ to prioritize traffic from time-critical devices like robotic arms or PLCs.

​​Deployment Best Practices​​

• ​​Cabling​​: Use Cat6a or higher shielded Ethernet cables for Multi-Gig ports to minimize crosstalk in high-noise industrial settings.
• ​​Redundancy​​: Deploy in a ​​HSR (High Availability Seamless Redundancy)​​ ring topology with sub-50ms failover for mission-critical systems.
• ​​Security​​: Activate MACsec on SFP+ uplinks and segment OT/IT traffic using VRF-lite to prevent lateral movement during breaches.
