FAQ
How many devices can this switch connect directly?
The Cisco SF350-48P provides 48 Fast Ethernet ports for direct device connections, supporting up to 48 wired devices simultaneously. This includes workstations, IP phones, security cameras, access points, and other network-enabled equipment. The switch also includes two additional Gigabit Ethernet network ports and four SFP expansion slots for uplink connections to other network segments or core infrastructure.
Does this switch support Power over Ethernet (PoE)?
Yes, the SF350-48P is a PoE switch that can deliver power to connected devices over the Ethernet cables. This eliminates the need for separate power adapters for compatible devices like IP phones, wireless access points, and security cameras. The built-in power supply provides stable voltage to all PoE-enabled ports, simplifying deployment and reducing cable clutter in office environments.
What is the difference between Layer 2 and Layer 3 switching on this device?
This switch operates at Layer 3, which means it can perform routing functions between different network segments or VLANs in addition to basic switching. Layer 3 capability allows for inter-VLAN routing, advanced traffic management, and improved network segmentation compared to Layer 2-only switches. This enables more sophisticated network designs with better traffic control and security isolation between departments or user groups.
Can I use fiber optic connections with this switch?
Yes, the switch supports fiber optic connections through its four SFP expansion slots. These slots accept standard SFP transceivers for connecting to fiber optic network segments. The switch is compatible with both multimode and single-mode fiber optics, providing flexibility for short-distance intra-building connections or longer-distance campus links. The shared SFP slot design allows for flexible uplink configuration based on your specific network requirements.
Is this switch rack-mountable or designed for desktop use?
The Cisco SF350-48P features a desktop form factor primarily designed for placement on shelves, under desks, or in equipment cabinets. While it doesn't include built-in rack ears for standard rack mounting, the included mounting kit provides options for wall mounting or under-desk installation. The compact dimensions of 1.45"H x 17.30"W x 13.78"D make it suitable for space-constrained environments where traditional rack space may not be available.
What management features are available on this managed switch?
As a fully manageable switch, the SF350-48P offers comprehensive management capabilities including web-based configuration, SNMP monitoring, VLAN configuration, QoS settings, and security features. The Layer 3 functionality adds routing protocol support, access control lists, and advanced traffic management options. The switch can be managed locally through the console port or remotely via network management systems, providing flexibility for network administrators to configure and monitor the device according to their specific requirements.
