NETGEAR GS748TP PROSAFE 48-PORT 10/100/1000 SMART POE SWITCH

• Brand: NETGEAR

• Model: GS748TP

• Series: ProSafe

• Type: 48-Port Gigabit Smart PoE Switch

• Management: Smart Managed (Web-based management)

• Stackable: Yes

• Dimensions: 440 x 438 x 43 mm

• Noise Level: 44.8 dB

• MTBF: 147,559 hours

• Status: Discontinued by NETGEAR

• Ideal for: growing businesses, classrooms, workgroups, and environments requiring multiple PoE connections

• Connects and powers up to 48 devices (Access Points, VoIP phones, IP cameras) over a single Ethernet cable

• Perfect upgrade for networks requiring advanced management without the complexity of a fully managed switch

• Saves installation time and costs by eliminating the need for separate power adapters for PoE devices

Note: This switch offers a total PoE budget of 384 W, allowing all 48 ports to be powered simultaneously (provided devices are within the power limit). For more demanding devices (such as PTZ cameras), it supports up to 4 PoE+ ports with up to 30 W per port.

Ports and Speed

• 48x Gigabit Ethernet ports (10/100/1000 Mbps) with Auto-Sensing and Auto Uplink™

• 4x Combo Gigabit SFP ports for fiber optic connectivity

• All ports support Power over Ethernet (PoE) per IEEE 802.3af

• MAC Address Table: 4,000 entries

• Switching Capacity: 96 Gbps (non-blocking)

• Forwarding Rate: wire-speed

Power over Ethernet (PoE)

• Total PoE Power Budget: 384 W (across all 48 ports)

• Max power per port: 15.4 W (802.3af)

• Supports up to 4 PoE+ ports (802.3at) with up to 30 W per port (for power-hungry devices like PTZ cameras)

• Intelligent power management: the switch only supplies power to devices that need it, optimizing the total budget

Management and Features

• Web-based management: intuitive interface for easy configuration and monitoring

• Security: 802.1x port authentication, Access Control Lists (ACL) for traffic filtering based on MAC or IP

• QoS (Quality of Service): traffic prioritization based on 802.1p and DSCP for latency-sensitive applications (VoIP, video)

• Rate Limiting: bandwidth control per port

• IGMP Snooping: multicast traffic optimization for more efficient streaming

• VLAN: supports IEEE 802.1Q for network segmentation

• Link Aggregation: port combining for extra bandwidth

• Broadcast Storm Control: protection against broadcast storms

• Jumbo Frame: support for larger frames for better performance

• Flow Control: supports IEEE 802.3x
