Zyxel GS1900-48HPv2 Gigabit Ethernet gestionado L2 (10/100/1000) Power over Ethernet (PoE) negro

The Zyxel GS1900-48HPv2 is a managed L2 Gigabit Ethernet switch with 48 PoE ports and a switching capacity of 100 Gbit/s. It supports IEEE 802.3af and 802.3at PoE standards and a MAC address table of 8000 entries. Designed for rack mounting and full-duplex operation, the switch provides reliable wired Gigabit performance suitable for small and medium businesses that need to power APs, IP cameras and VoIP phones over the network.

Advantages

The GS1900-48HPv2 offers near-silent operation thanks to either fan-less design or a smart fan that adjusts speed based on device temperature, making it suitable for office environments. Intelligent PoE+ management delivers only the actual power required by connected devices and optimizes the switch power budget so a single switch can power more endpoints. The series provides full non-blocking bandwidth of up to 1 Gbps per port and web-based smart management for VLAN, QoS, IGMP Snooping, Link Aggregation, IPv6 and DoS prevention.

Suitable for

• Small and medium business wired networks
• Powering access points, IP cameras and VoIP phones via PoE/PoE+
• Rack-mounted network closets and office network rooms
• Environments requiring quiet operation such as open offices

How to use

Mount the switch in a standard 19" rack or place it on a flat surface according to the rack-mounting instructions. Connect power and attach network devices to the RJ-45 ports; PoE-capable ports will supply power automatically to compatible devices following IEEE 802.3af/at. Access the web-based management interface via a browser to run the setup wizard, configure VLANs, QoS, IGMP Snooping, Link Aggregation and any security settings such as DoS prevention. Monitor PoE consumption and device status from the management interface to ensure optimal power distribution.

Recommendations

Place the switch in a well-ventilated area and ensure connected PoE devices do not exceed the total available PoE budget. Use the built-in wizard for initial configuration and enable only required services (VLANs, QoS, IGMP) to simplify management and reduce potential attack surface.
