Easily integrate the plug-and-play capable J9980A HPE OfficeConnect 1820 24G 24 Port Switch from HP into your existing network configuration, or tweak the switch to suit your specific networking needs. Whatever the needs of the network, administrators will have an easy time configuring and managing all aspects of the network thanks to a browser-based GUI. With a variety of advanced features including SNMP management, port mirroring, dual flash images, Network Time Protocol (NTP), manual network time configuration, and default DHCP client mode the J9980A can be tailored to serve the needs of nearly any business.

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
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

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
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

Secure Sockets Layer (SSL)
Encrypts all HTTP traffic, allowing secure accessto 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

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

Ease of Use
Locator LED
Allows usersto 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
