HPE OfficeConnect 1820 Switch Series devices are basic, smart-managed, fixed-configuration Gigabit Ethernet Layer 2 switches designed for small businesses looking for key features in an easy-to-administer solution. This series is part of the OfficeConnect portfolio of Hewlett Packard Enterprise small business networking products.
These switches are plug-and-play out of the box, yet network operation can be fine-tuned from a simple Web browser-based GUI, if necessary. Customizable features include VLANs, Rapid Spanning Tree, IGMP Snooping, link aggregation trunking, and DSCP QoS policies. All models include the latest energy-saving capabilities, including Energy Efficient Ethernet (EEE) and idle-port power down.

In the box

HPE OfficeConnect 1820 24G PoE+ (185W) 1U height switch with 12 RJ-45 autosensing 10/100/1000 PoE+ ports, 12 RJ-45 autosensing 10/100/1000 ports, 2 SFP 100/1000 Mbps ports, mounting hardware

Ideal for

The HP 1820 series switches are ideal for open offices that require silent operation or businesses making the transition from unmanaged to managed networks.


SFP ports for fiber connectivity

Provides fiber connections for uplinks and other connections across longer distances than copper cabling can support

Intuitive Web browser-based management

Allows easy customization of the switch even by non-technical users

Network Time Protocol (NTP)

Synchronizes timekeeping among distributed time servers; keeps timekeeping consistent among all clock-dependent devices within the network so that the devices can provide diverse applications based on the consistent time

Loop protection

Ff the switch detects a loop, it disables the source port from forwarding data packets originating from the switch to avoid broadcast storms

Port mirroring

Enables traffic on a port to be simultaneously sent to a network analyzer for monitoring

Broadcast control

Allows limiting of broadcast traffic rate to reduce unwanted network broadcast traffic

IEEE 802.1p/Q

Delivers data to devices based on the priority and type of traffic; supports IEEE 802.1Q.


Automatically adjusts for straight-through or crossover cables on all ports

Secure Sockets Layer (SSL)

Encrypts all HTTP traffic, allowing secure access to the browser-based management GUI in the switch.

Automatic denial-of-service protection

Monitors nine types of malicious attacks and protects the network by blocking these attacks.

IGMP snooping

Improves network performance through multicast filtering, instead of flooding traffic to all ports

IEEE 802.1p/Q VLAN tagging

Delivers data to devices based on the priority and type of traffic; supports IEEE 802.1Q
