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 includes a Limited Lifetime Warranty.

Features and benefits management

  • Simple web managementAllows for easy management of the switch—even by nontechnical users—through an intuitive Web GUI; supports HTTP and HTTP Secure (HTTPS)
  • SNMPv1, v2cEnable devices to be discovered and monitored from an SNMP management station
  • Port mirroringEnables traffic on a port to be simultaneously sent to a network analyzer for monitoring
  • Dual flash imagesProvide 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 configurationManually set the date and time on the switch in the absence of an NTP server
  • Default DHCP client modeAllows the switch to be directly connected to a network, enabling plug-and-play operation; in the 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 30 W 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 OfficeConnect 1820-8G-PoE+ (65W) switch; ports 1–12 provide PoE+ on the HPE OfficeConnect 1820-24G-PoE+ (180W) switch; ports 1–24 provide PoE+ on the HPE OfficeConnect 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 Link Layer Discovery Protocol (LLDP). Optionally, the switch permits manual, per port, PoE power configuration\
  • PoE shutdown mode - A PoE scheduler provides the ability to define the hours of PoE power being supplied to 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 shutdown - 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 being 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 9,220 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 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)
