HP 1820 Switch Series
Smart-managed, fixed-configuration Gigabit and Fast ethernet Layer 2 switches

HP 1820 Switch Series

Sorry, this product is no longer available, Please, contact us for a replacement product!

Overview:

The HP 1820 Switch Series offers more choice and flexibility for smaller organizations that require ease of use and lower TCO, while delivering better network performance with an enhanced user experience. HP 1820 Switch Series devices are smart-managed, fixed-configuration Gigabit Ethernet Layer 2 switches with basic features in an easy-to-administer solution.

The series includes 8-, 24- and 48-port non-PoE and PoE+ Gigabit Ethernet models. Specific models include SFP ports for fiber connectivity.

Some models are fanless, making them ideal for office deployments.

What's new:

  • Intuitive Web management interface with an enhanced navigation pane.
  • Non-PoE and PoE+ models for deployment flexibility.
  • Fanless design available on four models for quiet operation.
  • Customizable features for enhanced network performance.
  • Limited Lifetime Warranty 2.0 with 3 years of 24x7 phone support.

Features & Benefits:

  • 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 Enable 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 Provide 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 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) 3 Data sheet | HP 1820 Switch Series
  • 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 802.3afcompliant 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 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 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, and 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 network devices such as IP phones and access points, and allocate PoE power for more efficient energy savings

Warranty and support

  • Limited Lifetime Warranty 2.0

Advance hardware replacement with next-business-day delivery (available in most countries). See hp.com/networking/warrantysummary for duration details

  • Electronic and telephone support (for Limited Lifetime Warranty 2.0)

Limited 24x7 telephone support is available from HP for the first three years; limited electronic and business hours telephone support is available from HP for the entire warranty period.

Idle power is the actual power consumption of the device with no ports connected.
Maximum power rating and maximum heat dissipation are the worst-case theoretical maximum numbers provided for planning the infrastructure with fully loaded PoE (if equipped), 100% traffic, all ports plugged in, and all modules populated.
PoE Power is the power supplied by the internal power supply, it is dependent on the type and quantity of power supplies and may be supplemented with the use of a External Power Supply (EPS).
