Support for multiple security features, helping to protect the network from unauthorized access and other security threats.

PoE Capabilities

The J9983A HPE 1820-24G-PoE (185W) 24 Ports Managed Wall-Mountable Switch is a powerful and versatile switch that offers a wide range of features and capabilities to support your network infrastructure. One of the key features of this switch is its Power over Ethernet (PoE) capabilities.

Power over Ethernet (PoE) is a technology that allows power to be delivered to devices over Ethernet cables. This means that devices such as wireless access points, IP cameras, and IP phones can be powered through the same Ethernet cable that is used for data transmission, eliminating the need for separate power cables.

The J9983A HPE 1820-24G-PoE (185W) 24 Ports Managed Wall-Mountable Switch supports a total PoE power budget of 185 watts, which can be distributed across all 24 ports. This allows you to power a large number of PoE-enabled devices on your network, providing a convenient and efficient solution for powering your network infrastructure.

Additionally, the switch supports advanced PoE management features, such as automatic detection of PoE-enabled devices, power prioritization, and real-time power monitoring. This allows you to easily manage the power usage of your PoE-enabled devices and ensure that they are operating at optimal performance levels.

Management and security options

The J9983A HPE 1820-24G-PoE (185W) is a 24-port managed wall-mountable switch that offers a range of management and security options. These options include:

  • Web-based management: The switch can be managed through a web interface, which allows for easy configuration and monitoring of the network.
  • CLI (Command Line Interface): The switch also offers a CLI for advanced users who prefer to use command-line commands for network management.
  • SNMP (Simple Network Management Protocol): The switch supports SNMP, which allows for remote monitoring and management of the network.
  • VLAN (Virtual Local Area Network) support: The switch supports VLANs, which allows for segmentation of the network and improves security by isolating different traffic types.
  • Quality of Service (QoS): The switch supports QoS, which allows for prioritization of different types of traffic, such as voice and video.
  • Access control lists (ACLs): The switch supports ACLs, which allow for control of network access and improve security by limiting access to specific devices or users.
  • 802.1x Authentication: The switch supports 802.1x authentication, which allows for secure access to the network by requiring users to authenticate before being granted access.
  • Link Aggregation Control Protocol (LACP): The switch supports LACP, which allows for aggregation of multiple physical links to increase bandwidth and improve network resiliency.
  • DHCP Snooping: The switch supports DHCP snooping, which helps to prevent DHCP server spoofing and DHCP starvation attacks by monitoring DHCP traffic and allowing only authorized DHCP servers to respond to DHCP requests.
  • Storm Control: The switch supports storm control, which helps to prevent network congestion by limiting the amount of broadcast, multicast, and unknown unicast traffic that is allowed on the network.

About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

Different Types of Switches

Networking switches vary widely depending on the number of devices they can support, network bandwidth/speed, and form factor. Switches for small offices will have anything between 4 and 8 ports and can fit on a desk. For larger office network implementation, switches may have 24 ports, 48 ports, 96 ports, and 128 ports and are rack-mountable between 1U and 4U. Switches come in different types depending on the network speed and tasks they support. These include 40/100 Gbps, 10 Gigabit (up to 10000 Mbps), Gigabit Ethernet (up to 1000 Mbps), Power over Ethernet, and Fast Ethernet (10/100 Mbps).

Unmanaged Switches

The unmanaged switches offer fixed configuration on a plug-and-play basis. It is the most basic switch and there are a few choices in the market. These switches are affordable, but the basic features make them inappropriate for enterprise applications.

Managed Switches

The number of features and level of functionality improves with managed switches, making them ideal for enterprise and business applications. These switches are built with the command-line interface for ease of configuration. Equally, they support SNMP agents that come in handy when troubleshooting network issues.

The security on managed switches is better and will protect different types of traffic. Other features include support for virtual LANs, IP routing, and quality of service settings. Managed switches are more expensive compared to all other types of switches.

Smart Switches

Smart switches refer to switches that possess more features than those of unmanaged switches but do not have the full features of managed switches. Smart switches are more cost-effective than managed switches.

Some of the limitations of the smart switches are a lack of telnet access support, Web GUIs, and a lack of many features for VLANs. They are affordable compared to a fully managed switch and are suitable for a smaller computer network.

Modular Switches

Modular switches allow the addition of expansion modules as the network expands. The expansion modules allow for more networked devices but are application-specific. They may include wireless access points, firewalls, or network analysis tools. The flexibility of a modular networking switch comes at a higher cost.
