HP 1820-48G J9981A
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
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).
Enables devices to be discovered and monitored from an SNMP management station.
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 J9981A
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 J9981A
Allows limiting of broadcast traffic rate to reduce unwanted network broadcast traffic.
Delivers data to devices based on the priority and type of traffic; supports IEEE 802.1Q.
