Product Information

Keep workforces productive and the customer happy with the HP ProCurve (J4904A) 48-Ports Rack-Mountable Ethernet Switch 2800 Series. The latest version of the HP ProCurve offers a powerful network switch suited for medium to large offices. This rack-mountable device cost-effectively offers the maximum in bandwidth performance with 10 times the speed of regular switches. As an overview, this unit offers 44 type RJ-45 from 10base-t to 1000base-t ports, four dual-personality ports, and one RS-232C DB-9 console port. The dual-personality ports can be used as either RJ-45 ports or as mini-GBIC slots that can support SFP transceivers. The switch operating system is stored on disk drives on your PC. For offices with gigabit-enabled PCs, laptops, and servers, the HP ProCurve Switch 2800 Series allows you to access heightened performance times. These can be 10 times those of 100 Mbit switches. Intuitive HP web interface software makes customized operation a breeze. A host of additional features can be accessed to further layer the security of your network. IEEE 802.3, IEEE 802.3u, and IEEE 802.3ab are standard for media access control. Single IP address stacking management for up to 16 switches conserves IP addresses for easy web browser networking. Traffic prioritization improves the relay of data packets. VLAN tagging is supported to reduce traffic across the LAN and improve security. Link Aggregation Protocol (LACP) increases available bandwidth, and port trunking links VLANs across switches. All switches are backward-compatible for non-gigabit devices and can be connected without sacrificing speed of communication between devices. Migrating to an HP ProCurve allows business administrators and IT professionals to take full advantage of existing high-performance-enabled PCs, laptops, and servers. This leads to tangible savings as the existing architecture can noticeably improve application response and file transfer times. It increases performance between gigabit devices on your LAN and offers more bandwidth to be shared between devices on the gigabit Ethernet. The unique, fanless design of the HP ProCurve Switch 2800 Series keeps the system cool without drawing additional power or making excessive noise. In fact, the switch can operate at temperatures between 32 degrees Fahrenheit and 131 degrees Fahrenheit (0 degrees Celsius to 55 degrees Celsius). Hardware is included for easy horizontal mounting. It is compatible with a standard 120 VAC power supply, but it can interface with 200-240 VAC with a standard AC adapter. It offers Ethernet storage area solutions using the iCSCI standard and adheres to Cisco Fast EtherChannel (FAC) and Cisco Discovery Protocol (CDP).With so many useful features, the HP ProCurve (J4904A) 48-Port Rack-Mountable Switch 2800 Series technology protects existing investments while preparing you for future growth. For business purposes, this Ethernet switch will enable you to run multiple devices securely. It will also speed up interface times between devices on LAN for file transfers and data sharing. It improves broadband load-bearing capabilities and reduces traffic redundancy to improve performance. Additionally, it offers a convenient method for connecting multiple computers across a VLAN with configuration flexibility to meet your office's needs.
