Larch Computer Services was a 3Com Partner

3Com was acquired by Hewlett Packard in April 2010.  3Com's network switching, routing and security solutions were subsequently integrated in to HP's Procurve range and so 3Com products are now no longer available.

Larch Computer Services still carry a stock of used and refurbished 3Com products for support purposes.

A Basic Wired Network

Businesses must communicate and share information effectively to be competitive. Connecting individual PCs using a wired local area network (LAN) is a first step toward obtaining the many networking benefits.

The Solution
Larch Computer Services has all the components needed to build a wired Ethernet network to meet the needs of your small office. For a network of eight or fewer PCs, to share files and access common resources such as printers, use an Unmanaged 10/100 Switch.

Solution Fundamentals

Network Switches
At the centre of any network is a switch. Now more affordable than ever, switches are ideal for growing businesses.

Network Interface
To enable computers, printers, and other devices to talk to one another on a LAN, each requires a network interface. Most typically these interfaces are built in although this connection can be provided by a Network Interface Card (NIC). This card fits into a computer's expansion slot and provides the physical connection for the network's cabling.

Alternatives to this Solution

Need higher performance? You may consider Gigabit switches. These products are capable of operating compatibly with both 10/100 and 1000 Mbps equipment and provide very high-speed networking for video on demand, ultra-fast file transfer, and mission-critical applications. 

Need shared Internet access? Some devices combine multiple functions including a switch. Gateway routers are devices that allow a broadband Internet connection to be shared by multiple devices. They include switching and router functionality as well as security and firewall features so that LAN devices on the local network can securely access the Internet. The included switch can be used to build a network or to connect to an existing network.

Building a Wireless Network

With today's latest technology, you can do away with the cost and hassle of wires and still reap the benefits of networking.

Why go Wireless?
  • Cut installation costs: a wireless network is more economical than running wires
  • Easy to set up: installation is quick, and the network is portable, so it's easy to move as an organization grows and moves to a larger space
  • High speed: 300 Mbps speeds on 802.11n wireless networks make a wireless network a viable alternative for high-bandwidth usage
Understanding Wireless Standards

Speeds up to 11Mbps
Speeds up to 54Mbps
2.4GHz Frequency
5GHz Frequency
Compatible Standards

The Solution
Larch Computer Services has an extensive line of Wi-Fi compatible wireless networking products for your small office. For a network of up to 100 PCs, servers and printers, install a Wireless 11a/b/g/n Access Point. Laptops and desktops can use a wireless NIC or the wireless USB Adapter.

Alternatives to this Solution

Want shared Internet access and wireless connections? Gateways are devices that allow a broadband Internet connection to be shared by multiple devices., combining an access point, switch and gateway router for shared Internet access. 

Connecting to the Internet

The Internet is an essential activity for any business today. With the widespread adoption of e-mail, and new technologies such as "instant messages", an Internet connection is key to maintaining close ties with customers and keeping up with industry trends and competitive developments. Cable/DSL Gateway Routers provide secure wired and wireless connections to the Internet.

Why use a Gateway Router to access the Internet?
  • Economical Internet access: allows shared broadband access for an entire office
  • Improved network security: a shared connection is easier to protect
The Solution
The simplest solution for connecting small businesses to the Internet is to network a cable or DSL broadband Internet connection. The connection and basic equipment typically comes from the local Internet Service Provider.
