Zyxel GS1900-48-EU0102F - 48-port Gigabit Ethernet switch, Black

The Zyxel GS1900-48-EU0102F is a smart managed, 48-port Gigabit Ethernet Layer 2 switch designed for medium-sized offices. It features 48 Gigabit Ethernet RJ-45 ports for connecting computers, network storage, and IP devices. This non-PoE model is dedicated to data transmission and offers a switching capacity of 100 Gbit/s. A forwarding rate of 74 Mpps maintains consistent traffic flow without internal bottlenecks. The switch manages local area network segmentation and standard endpoint connectivity.

The rack-mountable chassis measures 440 x 200 x 44 mm and fits into standard network infrastructure. Administrators can configure network policies via a web-based interface, with SNMP and RMON support for remote monitoring. Layer 2 features include VLAN support for traffic segmentation and Quality of Service (QoS) to prioritise critical data streams. An internal fan provides cooling, and the unit consumes 36.9 W under typical operating conditions. Two SFP slots allow for fiber uplinks to core switches or external networks.

• 8,000-entry MAC address table for medium-scale endpoint tracking.
• 1.5 MB packet buffer to manage traffic spikes.
• Support for 9 kB jumbo frames for more efficient transfer of large data payloads.
• Mean time between failures (MTBF) of 229,313 hours.
• Link aggregation and Spanning Tree Protocol (STP) support to optimise bandwidth and prevent network loops.
