The general trademark of a manufacturer by which the consumer knows its products. A manufacturer can have multiple brand names. Some manufacturers license their brand names to other producers.
Product name:
Product name is a brand's identification of a product, often a model name, but not totally unique as it can include some product variants. Product name is a key part of the Icecat product title on a product data-sheet.
DGS-3048 - Managed Layer 2 Gigabit Switch
Product code :
The brand's unique identifier for a product. Multiple product codes can be mapped to one mother product data-sheet if the specifications are identical. We map away wrong codes or sometimes logistic variants.
Category :
A switch is a device with which it is possible to connect computers into a (local area) network, provided your computers all have an appropriate networking device installed. Switches can be daisy chained to form larger networks and come in managed and unmanaged variaties. The unmanaged versions generally cannot filter data and will forward any data that is fed into them, so they are better suited for small networks. Switches are easy to set up (just plug in the network cables) and allow you to share printers, storage space and other network resources with your entire home or office network.

The short editorial description of D-Link DGS-3048 - Managed Layer 2 Gigabit Switch
48-Port Gigabit L2 Switch with 4 Combo SFP and Management

Marketing text D-Link DGS-3048 - Managed Layer 2 Gigabit Switch

The official marketing text of D-Link DGS-3048 - Managed Layer 2 Gigabit Switch as supplied by the manufacturer
The D-Link DGS-3048 switch is a Layer 2 Gigabit switch that is an entry-level SNMP management solution for departmental networks. With high densities of copper Gigabit ports and multiple combo SFP, this stand-alone switch provide users with Gigabit-to-the-desktop connections with secure fiber access to the servers and network backbone. Powerful and versatile, this switch eliminate bottlenecks while giving users the capability to fine-tune performance. 1U height and standard rack-mount size is especially suitable for departmental environment, providing users the best performance/price ratio.

Network Management
The DGS-3048 switch addresses today's diverse business and IT requirements through robust support of standards based network management protocols (SNMP/RMON/Bootp/Telnet/Web) and port mirroring. By supporting standards-based network management protocols, this device can be easily integrated with most third-party network management products. The switch provides full duplex forwarding, 8k MAC addresses and the ability to classify and mark traffic based on 802.1p or DSCP (future release) into priority queues.

Advanced Features
DGS-3048 brings enterprise functions to a new level of affordability without compromising advanced features, such as QoS, Multicast, VLANs, Port Trunking, Port Mirroring, Spanning Tree, Security, and Network Management. These features facilitate the deployment of applications across an enterprise, including: VoIP, streaming media, and multicast content delivery (IP video, software deployment, etc.). Security features include 802.1x port based access control, and support for RADIUS and TACACS+ servers.

Port Trunk & Redundancy Support
The switch can be used as a cost-effective Gigabit to the desktop solution or high performance backbone aggregation devices. With 802.3ad Link Aggregation support, multiple ports can be combined into a multi-link for higher bandwidth connections to servers or the network backbone. The switch can be connected to redundant power supply to maximize network uptime. In case of a power failure, the external power unit will automatically provide the required power to ensure continuous operation.

Investment Protection
With 4 SFP modules, the DGS-3048 can easily adapt to changes in customer media requirements without the need to perform an expensive upgrade. Users can migrate to more advanced solutions in the future, while still protecting a portion of their original investment.
