6. Installing a Network

Installing a network is disruptive and requires careful planning.

6.1 Installing the network's cable infrastructure will cause the biggest disturbance and take the most time.

• You will need to employ a specialist contractor.
• Install enough cabling and outlets to see you through any planned growth phases. Spare outlets let you add new computers without cost or delay. Having to add more outlets to an existing network is both disruptive and expensive.
• Ensure that the cabling supports high speeds (at least 100BaseT).
• Ensure that you retain a detailed drawing of the cabling to speed up fault-finding.
• Ensure that all the network cable links are tested during installation and that you obtain a copy of the test results.

6.2 Install the network hardware once the infrastructure is in place.

• Connect the network server and one desktop computer to configure the system.
• Check that all parts of the network server are working correctly.
• Install the network adaptor cards in each desktop computer.
• Install any other communications hardware you need, such as modems and routers.
• Use an uninterruptible power supply (UPS) to protect your server from power cuts and surges. Test this and any back-up devices you use.

6.3 Install the network software.

• Configure the network operating system software using the test desktop computer.
• Install any network applications on the main server.
• Check that the back-up software works correctly. You need to make a back-up of the entire system once you have loaded on to it all the software you use.
• Configure one of the desktop computers.
• Configure and run any network management software you use.
• Copy the desktop configuration to each desktop once you are fully confident the system is working.
• Establish access rights and passwords for individual users.
