Switch gerido TP-Link TL-SG1428PE 28 portas Gigabit com 24 portas PoE+

The TP-Link TL-SG1428PE is a managed 28-port Gigabit switch with 24 PoE+ ports and a 250 W total PoE power budget. Designed for mixed deployments of powered devices and regular wired equipment, it delivers gigabit connectivity for PCs, printers and IPTV while supplying IEEE 802.3af/at PoE+ power to IP cameras, access points and IP phones. The switch offers a 56 Gbit/s switching capacity, an 8000-entry MAC table and rack-mountable 1U form factor suitable for small business, office and surveillance networks.

Advantages

The TL-SG1428PE combines centralized power delivery and managed switching capabilities: 24 dedicated PoE+ ports provide up to 30 W per port within a 250 W budget, while management features such as VLAN, QoS and IGMP snooping help optimize traffic and improve security. Built-in PoE auto recovery and intelligent power management maintain stable operation by rebooting unresponsive powered devices and reallocating power when the budget is exceeded. A metal casing and professional thermal design support reliable operation in typical indoor environments.

Suitable for

• IP surveillance systems with multiple PoE cameras
• Wi‑Fi deployments using PoE access points
• Small to medium office networks with mixed PoE and non‑PoE devices
• Dormitory or hospitality networks requiring centralised power and management
• IP telephony with PoE IP phones

How to use

Mount the TL‑SG1428PE in a standard 19" rack or place it on a stable surface. Connect uplink and wired devices to the Gigabit RJ‑45 ports and attach PoE devices (IP cameras, access points, IP phones) to the 24 PoE+ ports. Use the web‑based interface or the management utility to configure VLANs, QoS, IGMP snooping and monitoring settings. Monitor PoE budget and device status from the interface; the switch will perform PoE auto recovery for unresponsive powered devices automatically.

Recommendations

For reliable operation, distribute high‑power PoE devices across ports to avoid concentrating load on adjacent ports; enable intelligent power management in the web interface to prioritise critical devices. Keep ambient temperature within the specified 0–50 °C range and ensure adequate rack ventilation.
