Wall-mountable design and dimensions
The J9983A HPE 1820-24G-PoE (185W) is a 24-port managed switch that is designed to be wall-mountable. This means that the switch can be mounted on a wall or other flat surface, making it easy to install and saving space in the process.
The dimensions of the switch are 440mm x 190mm x 44mm (17.3in x 7.5in x 1.7in), which makes it relatively compact and easy to fit into tight spaces. It has a weight of 2.6 kg (5.7 lb) which is also considered lightweight.
The switch has 24 Gigabit Ethernet ports that support Power over Ethernet (PoE) with a total PoE budget of 185 watts. This means that the switch can power devices such as IP cameras, wireless access points, and IP phones directly through the Ethernet cable, eliminating the need for separate power supplies.
The J9983A HPE 1820-24G-PoE (185W) 24 Ports Managed Wall-Mountable Switch is a network switch that is compatible with a wide range of devices and systems. This switch is designed to work with HPE ProCurve, Cisco, and other major brands of network equipment, making it a versatile and flexible solution for any network environment.
The switch features 24 Gigabit Ethernet ports, which can be used to connect a variety of devices such as servers, workstations, printers, and storage devices. It also includes Power over Ethernet (PoE) capabilities, which allows you to power devices such as IP phones and wireless access points directly from the switch, eliminating the need for additional power sources.
The switch is also managed, which means it can be configured and monitored remotely using a web-based interface or through a command-line interface. This allows for easy monitoring and troubleshooting of the network, and allows for quick and easy configuration changes to be made as needed.
Power and Innovation
The J9983A HPE 1820-24G-PoE (185W) 24 Ports Managed Wall-Mountable Switch is a high-performance network switch designed for small and medium-sized businesses. It is equipped with 24 Gigabit Ethernet ports, 4 of which are PoE (Power over Ethernet) ports that can supply power to devices such as IP phones, cameras, and wireless access points.
The switch is managed, which means it can be configured and monitored through a web interface or through a command-line interface. It also supports advanced features such as Quality of Service (QoS), VLANs, and Link Aggregation Control Protocol (LACP).
One of the key features of this switch is its high PoE power budget of 185W. This allows it to support more PoE devices than other switches in its class, making it an ideal choice for businesses that need to power multiple devices on the network.
In terms of innovation, the J9983A HPE 1820-24G-PoE switch is designed with a compact and wall-mountable form factor, making it easy to install and save space in a small office environment. Additionally, it supports the latest network protocols and standards, such as IPv6 and Energy Efficient Ethernet, ensuring that it is ready to handle the latest network technologies and trends.

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).
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.
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 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 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.
