Deployment / Use Cases
The SISPM1040-3248-L-LA is ideal for environments requiring reliable, managed switching with both copper and fiber connectivity. Its feature set addresses common challenges in modern business networks.
In multi-tenant office buildings or business parks, the switch can segment network traffic between different tenants while providing PoE to shared devices like wireless access points in common areas. Educational institutions can use it to power classrooms full of VoIP phones and wireless projectors while maintaining separate VLANs for administrative and student traffic.
Medium Business Core Switching
Acts as a core or distribution switch for offices with 50-200 users, aggregating access switches and connecting to servers or storage via 10G uplinks.
IP Surveillance Backbone
Powers and connects multiple high-resolution IP cameras over PoE, with 10G uplinks ensuring smooth video feed aggregation to the NVR.
Physical Profile
Designed for standard 19-inch rack mounting, the switch occupies 1U of rack space with a depth of 11.81 inches. Its compact dimensions and moderate weight of 11.02 pounds make it easy to integrate into existing server cabinets or networking closets. The fanless construction not only reduces noise but also minimizes points of failure, contributing to overall system reliability.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 1.73" (43.94 mm), 17.40" (441.96 mm), 11.81" (299.97 mm), 11.02 lb (4998.59 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.
