User Manual
FAQ
What is the total PoE budget of this switch?
The Transition Networks SISPM1040-3166-L provides a 250W total PoE budget, which can be distributed across its 16 Gigabit Ethernet PoE+ ports. This substantial power allocation supports multiple PoE+ devices simultaneously, such as wireless access points, security cameras, and VoIP phones, while maintaining optimal switch performance. The budget management ensures efficient power distribution without overloading the switch's power supply.
How many expansion slots does this switch have for uplink connections?
This switch includes six expansion slots total: four SFP slots for Gigabit fiber connections and two SFP+ slots for 10 Gigabit Ethernet uplinks. These expansion capabilities allow for flexible backbone connectivity using either copper or fiber optic media. The combination of SFP and SFP+ slots enables scalable network architecture with options for both current Gigabit and future 10 Gigabit requirements.
What does 'Layer 4 supported' mean for this managed switch?
Layer 4 support indicates this switch can inspect and manage traffic at the transport layer (TCP/UDP) of the OSI model. This enables advanced features like traffic classification based on application ports, bandwidth limiting per application, and quality of service policies that prioritize critical business applications. Layer 4 capabilities provide more granular control than basic Layer 2/3 switching, making it suitable for networks requiring application-aware traffic management.
Is this switch suitable for industrial environments?
Yes, the hardened design with IP30 protection makes this switch suitable for industrial environments. The IP30 rating provides protection against solid objects larger than 2.5mm, and the fanless operation prevents dust ingress that could affect cooling systems. The wide operating temperature tolerance and dual power input options (AC/DC) further enhance its suitability for manufacturing facilities, warehouses, and other challenging environments where conventional switches might fail.
What management protocols are supported?
This managed switch supports TFTP, HTTP, and HTTPS protocols for configuration and monitoring. These protocols enable secure remote management through web interfaces and automated configuration deployment. The HTTPS support ensures encrypted communication for management sessions, while TFTP facilitates firmware updates and configuration backups. The comprehensive management capabilities allow network administrators to configure VLANs, QoS policies, PoE settings, and monitor switch performance.
What are the physical dimensions and rack requirements?
The switch measures 1.73 inches (44mm) in height, 17.40 inches (442mm) in width, and 11.81 inches (300mm) in depth, conforming to a standard 1U rack-mountable form factor. It weighs approximately 10.58 pounds (4800g) and installs in standard 19-inch equipment racks using included mounting hardware. The compact design maximizes port density while maintaining adequate passive cooling through ventilation, making it suitable for space-constrained network closets and server rooms.
