Product overview
HP 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.
The series consists of 6 switches including 8-, 24- and 48 port Gigabit Ethernet switches and 8-, 24-, and 48 port Gigabit PoE+
models each providing non-blocking Gigabit per port performance. Some models include SFP ports for fiber connectivity and some
are fanless, making them ideal for office deployments. All 1820 Switches support flexible installation options, including mounting
on wall, under table, or on desktop. The 8-port Gigabit Ethernet model can be powered by an upstream Power over Ethernet (PoE)
switch for environments where no line power is available.
These Gigabit switches are 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. 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.
Features and Benefits
Management
Simple Web management
Allows for easy management of the switch—even by nontechnical users—through an intuitive Web GUI; supports HTTP
and HTTP Secure (HTTPS).
SNMPv1, v2c
Enables devices to be discovered and monitored from an SNMP management station.
Port mirroring
Enables traffic on a port to be simultaneously sent to a network analyzer for monitoring.
Dual flash images
Provides independent primary and secondary operating system files for backup while upgrading.
Network Time Protocol (NTP)
Synchronizes timekeeping among distributed time servers and clients; keeps timekeeping consistent among all clockdependent devices within the network.
Manual network time configuration
Manually set the date and time on the switch in the absence of an NTP server.
Default DHCP client mode
Allows the switch to be directly connected to a network, enabling plug-and-play operation; in absence of a DHCP server

on the network, the switch falls back to a default, fixed IP address.
Quality of Service (QoS)
Traffic prioritization
Provides time-sensitive packets (like VoIP and video) with priority over other traffic based on DSCP or IEEE 802.1p
classification; packets are mapped to eight hardware queues for more effective throughput.
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.
Connectivity
Auto-MDI/MDIX
Automatically adjusts for straight-through or crossover cables on all ports.
IEEE 802.3X flow control
Provides a flow throttling mechanism propagated through the network to prevent packet loss at a congested node.
Loop protection
If the switch detects a loop, it disables the source port from forwarding data packets originating from the switch to avoid
broadcast storms.
SFP ports for fiber connectivity
Provides fiber connections for uplinks and other connections across longer distances than copper cabling can support;
SFP ports are in addition to available copper Ethernet ports, providing a higher total number of available ports. SFP ports
available on 24- and 48 port models.
IEEE 802.3af PoE-powered device option
Obtains power provided by a standard PoE device connected to Port 1; deploy the switch wherever an Ethernet cable can
reach as a power outlet is not needed (8-port GbE non-PoE+ model only).
IEEE 802.3at Power over Ethernet (PoE+)
Provides up to 30W per port, which allows support of the latest PoE+-capable devices such as IP phones, wireless access
points, and security cameras, as well as any IEEE 802.3af-compliant end device; lowers the cost of additional electrical
cabling and circuits that would otherwise be necessary in IP phone and WLAN deployments.
PoE+ port availability
Ports 1-4 provide PoE+ on the HP 1820-8G-PoE+ (65W) switch. Ports 1 – 12 provide PoE+ on the HP 1820-24G-PoE+
(180W) switch. Ports 1-24 provide PoE+ on the HP 1820-48G-PoE+ (370W) switch.
Auto PoE power configuration
The switch automatically assigns the required power to a port for a PD device based on LLDP (Link Layer Discovery
Protocol). Optionally, the switch permits manual, per port, PoE power configuration.
PoE shut down mode
A PoE scheduler provides the ability to define the hours of PoE power being supplied on a group of switch ports based on
a 24 hour day. The scheduler enables the flexibility to select individual days of a week as well as reoccurrence on a weekly
basis with a start and end date.
Energy Efficient Ethernet
Compliant with IEEE 802.3az standard requirements to save energy during periods of low data activity.
Auto port shut-down
The switch saves power by automatically shutting down power to inactive ports. Power is restored on a port upon link
detection.
Energy savings status
The switch provides an estimated cumulative energy savings due to green Ethernet features enabled.
Security
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.
Management password
Provides security so that only authorized access to the Web browser interface is allowed.
Performance
Half-/full-duplex auto-negotiating capability on every port
Doubles the throughput of every port.
IGMP snooping
Improves network performance through multicast filtering, instead of flooding traffic to all ports.
Layer 2 switching
VLAN support and tagging
Supports up to 64 port-based VLANs and dynamic configuration of IEEE 802.1Q VLAN tagging, providing security between
workgroups.
Jumbo packet support
Improves the performance of large data transfers; supports frame size of up to 9220 bytes.
Resiliency and high availability
IEEE 802.1D Spanning Tree Protocol (STP) and IEEE 802.1W Rapid Spanning Tree Protocol (RSTP)
Provides redundant links while preventing network loops.
Link aggregation (trunking)
Brings together groups of ports automatically using Link Aggregation Control Protocol (LACP) or, manually, to form an
ultra-high-bandwidth connection to the network backbone; helps prevent traffic bottlenecks; the 8 port models support
four trunks, the 24-port models support eight trunks and the 48-port models support 16 trunks. The 8- and 24-port
switches can support up to four trunk members, the 48-port switches can support up to eight trunk members.
Ease of use
Locator LED
Allows users to set the locator LED on a specific switch to either turn on, blink, or turn off; simplifies troubleshooting by
making it easy to locate a particular switch within a rack of similar switches.
Comprehensive LED display with per-port indicators
Provides an at-a-glance view of status, activity, speed, and full-duplex operation.
Flexibility
Flexible installation
Allows mounting on wall, desktop, or under-table with supplied hardware.
Rack mountable
All models include rack-mounting hardware for mounting in a standard 19 inch telco rack.
Kensington lock slot
Allows switches to be physically secured in open-space deployments (8-,and 24 port models).
Convergence
LLDP-MED (Media Endpoint Discovery)
Defines a standard extension of LLDP that stores values for parameters such as QoS and VLAN to automatically configure
