Cradlepoint TAA-MBA3-2155-5GB-GA 4-Port 2.5G Ethernet Switch
Overview
The Cradlepoint TAA-MBA3-2155-5GB-GA is a compact, fixed-port network switch designed for enterprise and managed service provider (MSP) deployments where procurement regulations or security policy mandate Trade Agreements Act compliance. This 4-port switch delivers 2.5 Gigabit Ethernet on every port—a step up from legacy 1G infrastructure—making it suitable for branch offices, secure network refresh projects, and environments where regulatory alignment is non-negotiable.
Key Features
- Four 2.5 Gigabit Ethernet Ports: All ports run at 2.5G, eliminating speed bottlenecks between connected devices. Unlike mixed-speed switches (which often reserve high bandwidth for uplinks), this design means every connected endpoint gets the same throughput tier—useful when branch offices need consistent performance across access points, cameras, or storage appliances. No port hierarchy to plan around.
- TAA Compliance Certification: Meets Trade Agreements Act requirements for federal procurement and regulated enterprise deployments. If your procurement process requires TAA-certified hardware (Section 889 of FISMA regulations, federal GSA contracts, or similar restrictions), the TAA-MBA3-2155-5GB-GA qualifies without workarounds or exemption requests. Eliminates a common gate in the approval cycle.
- Compact Form Factor: Fixed 4-port design means no modularity, but also no unnecessary chassis overhead or fan noise. Ideal for small branch offices, network cabinets with space constraints, or deployments where you need exactly four ports and nothing more.
- Standard Ethernet Connectivity: Supports any standard 802.3 Ethernet device—IP cameras, wireless access points, industrial controllers, or servers. 2.5G capability future-proofs branch links without requiring a hardware refresh when endpoint equipment upgrades to multi-gig NICs.
- 3-Year Warranty: Covers manufacturing defects and hardware failure. Standard replacement logistics apply; confirms vendor support commitment for the product lifecycle.
Integration and Deployment Context
Deploy the TAA-MBA3-2155-5GB-GA in branch office core networks where all connected devices need uniform 2.5G access—for example, between a building's access control controller, IP video NVR, Wi-Fi 6 mesh access point, and WAN gateway. The 4-port constraint is intentional: if you need more ports or mixing of speed tiers (1G + 10G), consider a larger modular switch family in the Cradlepoint line or another vendor's portfolio. The TAA compliance is the primary differentiator for regulated sectors; if your procurement rules don't require it, evaluate generic 2.5G switches on price and feature parity alone.
Typical Use Cases
- Branch office or remote site network core—consolidates access point, camera, and controller traffic on 2.5G links.
- Federal or GSA-contract-bound enterprise refresh—TAA compliance satisfies procurement audits without exceptions.
- Secure infrastructure lab or test environment—compact size, no modularity reduces management surface.
- MSP backbone refresh—homogeneous port speed simplifies inventory and reduces per-site configuration variance.
When to Choose a Different Model
If your deployment needs more than four ports, a larger managed or unmanaged switch from the same vendor or a third-party manufacturer is necessary. If you need mixed speed tiers (1G uplink + 10G trunk), look for modular or tiered switch families. If TAA compliance is not a procurement constraint, evaluate equivalent 4-port 2.5G switches from other vendors strictly on cost and warranty—functional differentiation at this tier is minimal.
Frequently Asked Questions
Q: Is the TAA-MBA3-2155-5GB-GA TAA-certified?
A: Yes. The TAA-MBA3-2155-5GB-GA carries TAA (Trade Agreements Act) certification, meeting federal procurement requirements and GSA contract compliance rules.
Q: What warranty is included with the TAA-MBA3-2155-5GB-GA?
A: A standard 3-year hardware warranty covers manufacturing defects and component failure under normal operating conditions.
Q: Can I use the TAA-MBA3-2155-5GB-GA with older 1 Gigabit Ethernet devices?
A: Yes. The 2.5G ports are backward-compatible with 1G and slower devices. Speed negotiation will drop to the device's maximum capability—no compatibility issue, but throughput will be limited by the slowest endpoint.
Q: Does the TAA-MBA3-2155-5GB-GA require special configuration or management software?
A: No. This is a fixed, unmanaged switch. Plug in Ethernet cables and power; no configuration interface or software licensing required. All ports are active by default.
Q: What power supply does the TAA-MBA3-2155-5GB-GA require?
A: Refer to the product datasheet for exact power specifications. Standard specifications are not confirmed in the available evidence; contact the manufacturer or distributor for power input details.
Q: Can the TAA-MBA3-2155-5GB-GA be wall-mounted or rack-mounted?
A: Physical mounting options are not detailed in the available evidence. Check the product datasheet or contact the manufacturer for form factor and mounting instructions.

The Cradlepoint TAA-MBA3-2155-5GB-GA is a straightforward, no-frills network appliance—and that's exactly the point. For a branch office core network or any TAA-regulated procurement scenario, this 4-port 2.5G switch eliminates complexity and certification risk in a single SKU.
Technical Highlights:
- Uniform 2.5G Port Configuration: All four ports operate at 2.5 Gigabit Ethernet, eliminating the speed asymmetry found in many entry-level switches (e.g., four 1G access ports + one 10G uplink). In a branch deployment connecting a Hikvision IP camera NVR, Wi-Fi access point, and access control reader, every device gets the same bandwidth tier—no scheduling or QoS gymnastics required.
- TAA Certification: Non-negotiable for federal procurement, GSA contracts, and regulated sectors. The TAA-MBA3-2155-5GB-GA carries this label in the hardware bill of materials—no workarounds, no exemption letters, no contract amendments. Saves weeks in approval cycles.
- Unmanaged Architecture: Fixed configuration, no VLAN management, no spanning tree tuning. Reduces attack surface (no management IP, no credentials) and eliminates operational overhead in small branches where IT staffing is minimal.
Deployment Considerations:
- 4-port hard limit: If your branch office grows beyond four networked appliances, this switch is inadequate. Plan for a larger sibling or replacement at design time.
- No managed features: Cannot isolate traffic, prioritize real-time video over data, or troubleshoot link issues remotely. Acceptable for simple branch topologies; problematic if you need granular control or analytics.
Best fit: federal or GSA-regulated enterprise branches with straightforward network architectures (router, access point, camera, controller—four devices, done). For commercial deployments without TAA constraints, equivalent unmanaged 4-port 2.5G switches from Netgear or Ubiquiti will cost 20–30% less with identical performance.
