The JG928A#ABA HPE 1920-48G-PoE Managed Switch is a high-performance switch designed for use in small to medium-sized businesses. It features 48 Gigabit Ethernet ports, with two of them being SFP ports for fiber connectivity. The switch also supports Power over Ethernet (PoE) with a total power budget of 370 watts, allowing it to power devices such as IP phones and cameras.
The switch has a maximum data transfer rate of 96 Gbps and supports a variety of advanced features such as Quality of Service (QoS), VLANs, and Link Aggregation Control Protocol (LACP). It also has a built-in web-based management interface, which allows for easy configuration and monitoring of the switch.
The switch is also built with security in mind, featuring support for Access Control Lists (ACLs), Port Security, and Secure Shell (SSH) for remote management. It also has a built-in redundancy feature, which allows for automatic failover in the event of a power outage or network failure.
In terms of physical specifications, the switch has a 1U rack-mount form factor and is powered by an external power supply. It has a maximum power consumption of 370 watts and supports operating temperatures between 0°C and 40°C.
Power over Ethernet (PoE) Capabilities
The JG928A#ABA HPE 1920-48G-PoE Managed Switch is a networking device that has the capability to provide power to connected devices through the Ethernet cables. This is known as Power over Ethernet (PoE) and it eliminates the need for separate power cables and outlets for devices such as access points, cameras, and phones.
The switch has a total PoE budget of 370W, which means it can provide a maximum of 370 watts of power to connected devices. It also supports both IEEE 802.3af and IEEE 802.3at PoE standards, which means it can provide power to a wide range of devices that require different power levels.
The switch also has advanced management capabilities, such as the ability to monitor and control the power usage of connected devices, and the ability to prioritize power allocation to ensure that critical devices receive the power they need.

About Refurbished Products
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.
