Description

The HP 1820-48G is a smart-managed, fixed-configuration 48 port Layer 2, Gigabit Ethernet switch. It’s designed for small businesses looking for key features in an easily-administered solution.

The fanless J9981A switch includes 4 x SFP ports for fibre connectivity, making it ideal for office deployments. Installation options are flexible since the HP 1820-48G can be mounted on a wall, under the desk, or on a desktop. Please see the ‘accessories’ tab for the HP X410 1U Universal 4-post rack-mounting kit.

The J9981A Gigabit switch is plug-and-play out of the box, yet network operation can be fine-tuned through features available from a simple Web browser-based GUI, if necessary. Customisable features include VLANs, Rapid Spanning Tree, IGMP Snooping, link aggregation trunking, and DSCP QoS policies.

This model features the latest energy-saving capabilities, including Energy Efficient Ethernet (EEE) and idle-port power down.
