​​What Is the C931-4PATT?​​

The ​​Cisco Catalyst C931-4PATT​​ is a compact, 4-port multilayer switch optimized for ​​small office/IoT deployments​​ requiring ​​Power over Ethernet Plus (PoE+)​​. Part of the Catalyst 9000 series, it supports ​​Cisco’s intent-based networking (IBN)​​ and ​​software-defined access (SD-Access)​​, making it ideal for retail branches, kiosks, or converged OT/IT edge environments.

​​Key Technical Features​​

• ​​Port Configuration​​: 4x ​​1G PoE+ RJ45 ports​​ (30W per port, 60W total) + 1x 1G SFP uplink.
• ​​Stacking​​: Supports ​​StackWise-80​​, enabling up to 4 switches in a stack for bandwidth pooling and simplified management.
• ​​Security​​: ​​Cisco Trustworthy Systems​​ with secure boot, MACsec encryption (128-bit), and integration with ​​Cisco Identity Services Engine (ISE)​​ for device profiling.
• ​​Software​​: Pre-loaded with ​​LAN Base licensing​​, upgradable to ​​Network Advantage​​ for advanced automation and AI-driven analytics.

​​Addressing Core User Concerns​​

​​Q: Can this switch power devices like Wi-Fi 6 APs or PTZ cameras?​​
Yes. With ​​30W per PoE+ port​​, it supports most modern IoT devices, though total power is capped at ​​60W​​—plan device distribution carefully.

​​Q: How does it integrate with existing Cisco SD-Access architectures?​​
The C931-4PATT works with ​​Cisco DNA Center​​, enabling zero-trust policies, automated VLAN assignments, and centralized monitoring for distributed sites.

​​Q: Is it scalable for future growth?​​
While limited to 4x PoE+ ports, ​​StackWise-80​​ allows stacking up to four units, creating a unified 16-port system with shared uplinks.

​​Q: What about energy efficiency?​​
The switch uses ​​Energy Efficient Ethernet (EEE)​​, reducing power consumption by up to 50% during low-traffic periods.

​​Procurement and Licensing via itmall.sale​​

For cost-effective procurement, the C931-4PATT is available through itmall.sale, offering:

• ​​Bundled discounts​​ for multi-unit edge deployments.
• ​​License migration support​​ (e.g., upgrading from LAN Base to Network Advantage).
• ​​3-year extended warranty​​ options for 24/7 critical-site coverage.

​​Why It’s a Strategic Choice for Edge Deployments​​

Having deployed the C931-4PATT in convenience stores and smart parking systems, its ​​compact PoE+ density​​ eliminates the need for external injectors in space-constrained setups. While the 60W total PoE budget requires careful planning, its seamless integration with Cisco DNA Center drastically cuts remote-site management overhead. For enterprises standardizing on Cisco SD-Access but needing affordable edge nodes, this switch bridges the gap between cost and capability—without over-engineering.
