Modern campus edges have to push more traffic than ever—Wi-Fi 6/6E backhaul, cloud SaaS, UHD video, and IP surveillance—without adding operational drag. The NS-S5310 Switches from Network-Switch give you that balance: robust Layer 3 switches with gigabit copper access, SFP+ 10G uplinks, and mature O&M—delivered as your product (front-bezel logo, exterior style, and day-0 software templates are all customizable).
In other words, you get the same-class “speeds and feeds” you expect from premium Ethernet switches, plus the freedom to ship a consistent, branded experience across every closet.
The NS-S5310 family follows the widely deployed S5310 class: full-gigabit access with 4× 1G/10G SFP+ uplinks, VSU stacking, ERPS ring protection, IPv4/IPv6 routing (static, RIP, OSPF, IS-IS, BGP), and strong edge security and manageability. These capabilities are documented in publicly available series datasheets and product pages.
Product Overview
Where it fits. NS-S5310 Switches are campus/enterprise Access Switches that can also serve as compact distribution nodes thanks to Layer 3 features and 10G uplinks. Highlights include:
- Ports & uplinks: 24/48 × 10/100/1000 RJ45 ports for access, plus 4× SFP+ (1/10G) uplinks across the family. Fiber-access variants provide 24/48 SFP downlinks for all-optical floors.
- L3 & virtualization: Dual-stack IPv4/IPv6 at line rate; static, RIP/RIPng, OSPFv2/v3, IS-IS(v4/v6), and BGP4/BGP4+; VSU virtualization/stacking for single-plane management and millisecond failover.
- Resiliency: ERPS (G.8032) ring protection, RSTP/MSTP, BFD for fast convergence, and RLDP/loop-guard tools for edge hygiene.
- Security: DHCP Snooping, IP Source Guard, Dynamic ARP Inspection, CPU Protect Policy (CPP) / NFPP, 802.1X (port/MAC), and granular ACLs.
- PoE+ models: PoE SKUs support IEEE 802.3af/at with scheduled power, priorities, and hot-start continuity; published budgets reach 740 W (24-port PoE+) and 1440 W (48-port PoE+), with 370 W / 740 W modular PSUs.
- Operations: Web UI, CLI/SSH, SNMP, Syslog/RMON, sFlow, zero-touch via CWMP; hot-swap SFP+ optics with live optics telemetry.
Customization (your differentiator). With Network-Switch, you can pre-load VLAN plans, QoS/AAA/SNMP/Syslog, port-role templates (AP/phone/camera/user), banners/CLI prompts, and ship the chassis with your logo and colorway. That makes day-0 truly plug-and-go—at scale.

Deployment Scenarios
10G-uplink access with PoE (NS-S5310-24/48GT4XS-P-E)
Deploy PoE+ Access Switches where APs, VoIP, and PTZ cameras cluster. Use 2× or 4× SFP+ uplinks in LACP for active-active throughput and fast failover. Schedule PoE by policy windows; leverage port priority to protect mission-critical endpoints during power budget contention. Published budgets of 740 W (24-port) and 1440 W (48-port) give you planning headroom.
High-density copper floors (NS-S5310-48GT4XS-E)
When you don’t need inline power, 48 copper drops with 4× SFP+ uplinks provide ample backplane (176 Gbps / 131 Mpps) for traffic spikes, and you still keep full L3/VXLAN capabilities for segmentation.
All-fiber wings & labs (NS-S5310-24/48SFP4XS-E)
For EMI-heavy environments or long runs, Fiber Switch variants give you SFP downlinks and the same SFP+ uplinks—ideal for optical-first closets and research labs. Pair with VSU for single-plane management across wings.
Compact distribution / routed access (any NS-S5310)
Use static/OSPF or IS-IS at the floor, push default routes from aggregation, and let BFD drive fast failover. VXLAN allows gradual migration to overlay-friendly designs without forklift upgrades.
Optics & Cabling Guidance
| Uplink Type | Recommended Optics / Cables | Typical Use Case | Notes |
| SFP+ (10G) on all “4XS” models | 10G SR/LR SFP+; 10G DAC/AOC | Campus/distribution 10G backbones | SR for OM3/OM4 short runs; LR for SMF up to 10 km; hot-plug with optics telemetry. |
| SFP (1G) on fiber-access models | 1G SX/LX/BiDi SFP | All-fiber access, EMI-sensitive areas | Use BiDi to halve strands; follow IEEE/MSA optics guidance. |
| RJ45 access (10/100/1000) | Cat5e/Cat6 twisted pair | PCs, phones, printers, cameras | ≤100 m runs; enable EEE where supported to reduce draw. |
| Redundancy | LACP over SFP+; ERPS rings between closets | Active-active uplinks; ring protection | ERPS delivers sub-50 ms recovery on rings; pair with MSTP at edges. |
NS vs. Fixed-Brand Access Switches
| Feature / Aspect | NS-S5310 Switches | Fixed-Brand OEM Access Switches | Other Third-Party Resellers |
| Performance & Specs | Same-class hardware: 1G access + 4× 10G SFP+; L2+/L3 with VXLAN, VSU, ERPS | OEM-grade; features sometimes tied to proprietary optics/licensing | Mixed; may include re-badged/refurb gear |
| Customization | Full exterior + software defaults (logo, bezel, VLAN/QoS/AAA templates) | Branding/defaults fixed; little personalization | Minimal cosmetics; config done post-purchase |
| Compatibility | Standards-aligned SFP+/SFP/RJ45; multi-vendor optics flexibility | Potential vendor lock on optics/features | Varies; CLI workarounds often required |
| After-Sales Support | 24/7 helpdesk, fast RMA, ongoing EEPROM/firmware updates | Business-hours support; 5–7-day RMA typical | Limited support; 7–14-day RMA common |
| Pricing & TCO | Often ~30% below OEM; no hidden licenses | Premium list price; feature licenses possible | Slightly cheaper than OEM with fewer guarantees |
| Inventory & Lead Time | Custom SKUs; pre-configured “ready-to-deploy” units | Standard SKUs only | Inconsistent stock; long-tail lead times |
Operations, Visibility & Security
- Zero-touch day-0: We ship your standard image/config—VLAN plan, LACP/RSTP defaults, ERPS topologies, AAA, SNMP/Syslog endpoints, and per-port roles—so installers just patch and power.
- Faster troubleshooting: With CLI/SSH, SNMP, Syslog, RMON, and sFlow, plus optics power readouts and temperature/fan signals, you can diagnose remotely without truck rolls.
- Edge hygiene by default: Enable DHCP Snooping + IP Source Guard + DAI and ARP-rate-limit; turn on BPDU guard and storm controls; let CPP/NFPP shield the CPU from floods.
