The HP (JE737A) was formerly sold as the 3Com (3C16486)
HP SuperStack 3 4400 24-port PoE Switch.
Hewlett Packard (HP) acquisitioned 3Com back in 2010, and has since been supporting this same 3C16486 switch as a JE737A HP Baseline 48-port GbE Switch (part of their HP Baseline 2800/Gigabit Switch Series).
The JE063A and 3C17205 are the same product

HP Baseline 2824-SFP Plus 48-port GbE Switch (3C16486)
3Com Baseline 2848-SFP Plus 48-Port GBE Switch (3C16486) w/Fiber Gigabit Ethernet SX/LX support
Enterprise-class, Layer 2 10/100/1000 switch for small and medium businesses, with advanced features for network control and flexibility.
The 3Com® Baseline Switch SFP Plus is a “smart” cost-effective Layer 2 10/100/1000 Ethernet switch. This 48-port switch provides a user-friendly web browser interface for switch configuration and administration. With a low entry cost, they offer advanced features such as IEEE 802.3ad link aggregation, IEEE 802.1p class of service (CoS) traffic prioritization, and VLANs for greater scalability and support for business-critical applications—such as customer relation management (CRM), supply chain management (SCM) and video.
SMART BROWSER-BASED USER INTERFACE
The easy-to-use web-based interface allows even novice users to quickly and confidently configure the switch during initial setup or normal operation. In addition, the web interface features individual port-traffic monitoring (port mirroring) and unique, quick-glance switch status monitoring. A new cable diagnostic tool lets users troubleshoot basic connectivity cabling problems via the web management interface further simplifying network installation.
This switch has non-blocking performance—all ports perform at wirespeed which helps to eliminate network traffic bottlenecks. Link aggregation allows administrators to group any number of copper or fiber ports together to form an ultra-high bandwidth pipe that greatly expands bandwidth capacity to the network backbone. The switch also supports 802.1p for traffic prioritization and priority queuing, and VLANs, which segment the network by grouping users based on data or traffic exchange requirements. These switching features ensure optimal use of available bandwidth as traffic flow is directed according to the needs of the business.
ENTERPRISE-CLASS QUALITY AND RELIABILITY WITHOUT COMPLEXITY
This Baseline switch is operational straight out-of-the-box; as long as basic settings are acceptable, there is no need to configure the switch. For networks that require more control, the user-friendly web-based interface provides easy-to-use tools to design a network for optimal use.
