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. 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. 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. 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.
...Dlink DES 1008D
Why a switch?
Switches are the backbones of a network. They are the devices that at all the computers in the office have no choice but to use. They are a great tool in modern computer networks. The switch allows communication between computers, servers and network printers.
What does a switch need to do?
1. Connect multiple computers
2. Be Fast
3. Be Reliable
4. Be user Friendly
So will the DES 1008D model handle the pressure?
1. Connectivity
The DES 1008D has a total of 8 ports witch means that you could have 8 computers connecting simultaneously, or you could have a variety or pcs, servers, printers, and other networks switches connecting to it.
8 ports will happily support a small office or home based network.
2. Speed
So we have found out that it has 8 ports so what will...

Advantages: Pick up a bargain ? Disadvantages: Only 4 ethernet ports ?
...Another review from me for a discontinued item, but may be useful if you're loking to pick up a bargain item on ebay...
The D-Link DSL-504 ADSL Router has a built-in ADSL modem - plugs directly into your ADSL (Asymmetric Digital Subscriber Line)-enabled phone line, and with its 4 port 10/100Mbps ethernet switch, allows connections to lots of things (check out my other reviews for what it's connected to...). The DCHP server allows automatic allocation of IP addresses to all your network gubbins too - although I've set the IP's for my wireless accesspoint & print server to allow easier access to their brower based interfaces.
The DSL-504 has a browser admin interface too for easy installation and setup, just type in the IP address (the default 192.168.0.1, as with most routers, but if it's changed you can always use the command line...

Advantages: Advantages: Cheap, all in one solution Disadvantages: No manual overide or audio support
...stops autoscanning and lets you use the currently selected PC.
The Belkin claims support for scrolling mice but I did find sometimes one PC would start up without recognising this facility if it wasn't the currently selected one when booting up and in extreme cases, wouldn't recognise the keyboard and mouse at all. Previous KVM's I've used send the PC fake 'There's a keyboard and mouse here' messages when not selected and it seems this unit does not, which is a pity.
Conclusion
The Belkin 2 port KVM is a well built unit that works nicely and provides a great way to save desk space and the cost of a second monitor, keyboard and mouse. The long leads are useful and despite the niggles with scrolling mice and the lack of manual switch. I'd say this unit is worth considering at this price if you can live with those shortcomings...
