User Manual
FAQ
What is the total PoE budget of this switch?
The Intellinet 508278 provides a total PoE budget of 240 watts across its eight Gigabit Ethernet ports. This budget supports simultaneous power delivery to multiple PoE+ devices such as IP cameras, wireless access points, and VoIP phones, with intelligent power allocation managed through the switch's PoE capabilities.
How many SFP uplink slots does this switch have?
This switch includes two SFP (Small Form-factor Pluggable) slots that support 1000Base-X fiber optic modules. These slots enable fiber uplink connections for extending network distance, connecting to fiber backbones, or overcoming electromagnetic interference in industrial environments where copper connections may be problematic.
Is this switch manageable, and what management features does it offer?
Yes, this is a fully manageable Layer 2 switch. It supports essential management features including VLAN configuration, Quality of Service (QoS) prioritization, port mirroring, and SNMP monitoring. The switch is also compatible with Domotz cloud management platform with a firmware upgrade, enabling remote monitoring and management capabilities.
What mounting options are available for this switch?
The switch is designed for DIN-rail mounting with an included bracket, making it ideal for industrial control panels and electrical cabinets. The compact dimensions (6.89" L x 5.51" W x 2.17" H) and metal construction ensure secure installation in space-constrained environments while providing durability for demanding applications.
What environmental conditions can this switch withstand?
With an IP30-rated metal housing and operating temperature range of -40°C to 85°C (-40°F to 185°F), this switch is built for harsh industrial environments. The metal construction provides protection against solid objects larger than 2.5mm while offering excellent heat dissipation across the full temperature spectrum.
What is the Powered Device Monitor feature?
The Powered Device Monitor (PDM) is a self-healing network feature that automatically detects when connected PoE devices become unresponsive or stop sending network traffic. When this occurs, the switch can automatically restart the affected device by cycling power to that port, minimizing downtime without manual intervention in critical network deployments.
