J4905A HP ProCurve 3400cl-24G 10/100/1000Base-T 24 Port Switch | Brand New 3 Years Warranty

The J4905A HP switch is a Layer 3 switch, meaning it is capable of performing routing and switching functions. This allows for more advanced network configurations, such as creating virtual LANs (VLANs) to segment the network and improve security. Additionally, it supports a variety of routing protocols, including Routing Information Protocol (RIP) and Open Shortest Path First (OSPF) which allow for efficient routing of data packets within the network.

The switch also supports Quality of Service (QoS) features, which allow you to prioritize certain types of network traffic, such as voice or video, to ensure that they are delivered with minimal delay and interruption.

It supports a total of 48 Gigabit Ethernet ports, which provide high-speed connectivity for devices on the network. And it also have 2 SFP+ ports for Fiber connectivity.

The J4905A HP switch also provides advanced security features such as access control lists (ACLs) and virtual private networks (VPNs) to help protect your network from unauthorized access and threats.

PoE is a technology that allows the electrical power to be carried over the same cable as the data, eliminating the need for a separate power source for network devices such as IP phones, wireless access points, and cameras. J4905A is a security and management module that does not have Ethernet ports, PoE functionality or other features related to data forwarding, and it does not have the capability to support Power over Ethernet (PoE).

It is designed to work in conjunction with ProCurve switches and routers to expand their security and management capabilities, but it does not have PoE functionality. If PoE is required, it would need to be provided by the switch or router that the J4905A is connected to.

Power over Ethernet (PoE) support allows devices such as wireless access points, IP cameras, and VoIP phones to receive power through the same Ethernet cable that is used to transmit data. The J4905A HP switch is a Power over Ethernet (PoE) enabled switch that allows you to power devices over the Ethernet cable, eliminating the need for separate power cables. This can be useful for devices that are located in areas where it is difficult or expensive to run separate power cables. The switch supports a total PoE power budget of 370W, which can be distributed among all the PoE-enabled ports.

The J4905A HP switch is a high-performance switch that is designed to handle a large amount of network traffic. With 24 Gigabit Ethernet ports, the switch can support high-speed connectivity for multiple devices on the network.

It supports non-blocking switching architecture, which means that all ports can operate at full wire-speed simultaneously, without any performance degradation.

The switch also supports Quality of Service (QoS) features, which allow you to prioritize certain types of network traffic, such as voice or video, to ensure that they are delivered with minimal delay and interruption.

The J4905A HP switch also supports advanced features such as Link Aggregation Control Protocol (LACP) and Virtual Router Redundancy Protocol (VRRP) to increase availability and resiliency of the network.

Additionally, the switch supports a total PoE power budget of 370W, which can be distributed among all the PoE-enabled ports.
