Model Selection Guide for C1000-48T-4G-L

  • High-density access for large wired networks – Ideal for enterprise offices, call centers, and campus environments requiring 48 simultaneous Gigabit connections for PCs, printers, and departmental servers.
  • Perfect for quiet, open workspaces – Fanless design ensures zero noise output, making it suitable for libraries, classrooms, medical offices, and other noise-sensitive areas.
  • Reliable aggregation to core or distribution layers – 4 × 1G SFP uplinks provide flexible fiber connectivity, ensuring stable, long-distance links without bottlenecks.
  • Cost-effective for non-PoE deployments – For environments where all devices are self-powered (e.g., desktop PCs, printers), this model eliminates unnecessary PoE investment while maintaining enterprise-grade performance.
  • Alternative options – For networks requiring PoE power delivery to APs, IP phones, or cameras, choose C1000-48P-4G-L. For smaller networks, the C1000-24T-4G-L offers similar capabilities with fewer ports.

Questions & Answers

  • What roles suit the Cisco C1000-48T-4G-L best?

    It’s a 48-port non-PoE Gigabit access switch with four 1G SFP uplinks, ideal for small offices, branches, and classrooms that need reliable wired connectivity without power delivery. It’s easy to deploy, simple to manage, and budget-friendly for large edge rollouts.

  • How does C1000-48T-4G-L compare with C1000-48P-4G-L?

    Both share 1G uplinks, but the 48P adds PoE+ for devices like phones, cameras, and APs. Choose the 48T when you only transport data and want lower power, heat, and cost; pick the 48P when you must power many endpoints directly from the switch.

  • Does C1000-48T-4G-L support VLANs and segmentation?

    Yes. It supports 802.1Q VLAN tagging, private VLAN features, and basic Layer 2 controls. You can segment staff, guest, and IoT traffic, then enforce policies with ACLs and 802.1X. This helps isolate sensitive systems and improve overall LAN security without complex routing.

  • Can I manage C1000-48T-4G-L without deep CLI skills?

    Yes. Use the onboard Web UI for quick wizards, port setup, VLANs, and monitoring. Cisco Business Dashboard can centralize multiple Catalyst 1000 switches for inventory and firmware tasks. CLI remains available for administrators who prefer scriptable, precise configuration.

  • What uplink choices does C1000-48T-4G-L offer?

    It provides four 1G SFP uplinks compatible with common fiber modules such as SX and LX/LH. This is sufficient for many SMB backbones or stacked uplinks via link aggregation. If you anticipate 10G backhaul, consider the C1000-48T-4X-L instead.

  • Is C1000-48T-4G-L appropriate for quiet office spaces?

    Yes. While it includes internal fans due to port density, the acoustic design suits wiring closets and standard office racks. For deskside silence, smaller fanless C1000 variants are better. Proper ventilation will keep temperatures stable and prolong hardware life.

  • How does C1000-48T-4G-L stack up against Catalyst 9200?

    Catalyst 9200 introduces StackWise, advanced Layer 3, and deeper automation. C1000-48T-4G-L focuses on fixed Layer 2 access, easy management, and affordability. If you need routing at the edge or large campus scaling, consider 9200; for simple access, choose C1000.

  • What security protections are available on C1000-48T-4G-L?

    It supports 802.1X, MAC port security, DHCP snooping, and ACLs to block spoofing and unauthorized access. Storm control and BPDU Guard further harden the edge, protecting distribution and core tiers from misconfigurations and noisy endpoints.

  • Can I use link aggregation to increase uplink bandwidth?

    Yes. EtherChannel lets you bundle multiple 1G uplinks to a distribution switch, improving throughput and redundancy. It’s an effective way to scale within the 1G framework when 10G hardware is not required or budgeted.

  • What are typical migration paths from C1000-48T-4G-L?

    As traffic grows, you can upgrade to C1000 models with 10G uplinks or move to Catalyst 9200/9300 for stacking and Layer 3. Reuse existing optics where possible and transition gradually, keeping this model in less demanding segments.
