Key features |
|
Product overview |
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. The series is part of the OfficeConnect portfolio of Hewlett Packard Enterprise small business networking products.
The series consists of six 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 the 8-, 24-, and 48-port non PoE+ models are fanless, making them ideal for office deployments. All HPE OfficeConnect 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. HPE OfficeConnect 1820 Switch Series is covered by a Limited Lifetime Warranty. |
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 clock-dependent 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 HPE 1820-8G-PoE+ (65W) switch. Ports 1 – 12 provide PoE+ on the HPE 1820-24G-PoE+ (180W) switch. Ports 1-24 provide PoE+ on the HPE 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
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 4 trunks, the 24-port models support 8 trunks and the 48-port models support 16 trunks. The 8- and 24-port switches can support up to 4 ports per trunk, the 48-port switches can support up to 8 ports per trunk
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).
