The work

A network is a system of computers and other communications equipment linked together to exchange information. Networks may be:

• local area networks (LANs), which link offices in one building or branches of a company
• metropolitan-area networks (MANs), linking offices across a region
• wide area networks (WANs) which link nationally or internationally and with the internet.

Network managers are responsible for installing and maintaining these computer networks and making sure that people can access the information they need. They are also responsible for installing and maintaining security systems which prevent unwanted users, frequently referred to as 'hackers', from entering the system.

Network managers may be employed by a large organisation, such as a bank, or may work as consultants, covering a number of smaller clients. Initially, they may have to design and set up a network in line with client needs, write programs for the network, set up user accounts and access, including passwords, and train staff to use the hardware and software.

Once the network is in operation, their job is to provide technical support and answer questions encountered by staff members, monitor file use to make sure that only authorised people are accessing particular files, change passwords, back up files to guarantee their safety in the event of problems with the network, ensure that adequate security is installed and working properly at all times and plan and implement future development.

Larger companies often employ several network managers, each of whom performs a different function. In smaller companies, one or two people do everything relating to network administration and maintenance.

Hours and Environment

Network managers tend to work a 37-40 hour week, Monday to Friday. They may need to work outside these hours when installing systems, so that the user's work is not disrupted, and they may be on call if breakdowns occur outside their normal working hours.

Network managers usually work in an office, and may be based at one site or, if involved in a large network operation, may travel between sites.

They spend some time in meetings with clients, sometimes at a high level of management, and will have to work closely with staff using the network.

Skills and Interests

Network managers should:

• have writing and presentation skills
• be able to express themselves clearly to people with little knowledge of computers
• be able to work within a team
• have a logical, analytical approach to work
• have good negotiating skills
• be good with figures for calculating costs
• be interested in solving problems
• be interested in IT and able to use a computer
• be interested in general business activity.

Entry

Although there is no set upper age limit for entry to this work, mature applicants may have difficulty getting in unless they have relevant business experience and some IT training. Many people develop computer skills when working in other fields, such as financial services, insurance, banking or accounting.

• A computer-related degree is not essential for entry as training may be available in-house.
• Universities and colleges may accept mature applicants for courses without the usual entry requirements, particularly if they have relevant qualifications or experience. They may also accept applicants who have successfully completed an Access course. Many local colleges offer Access courses, usually over one year full-time or two years part-time.
• It is possible to begin training for this work straight from school with good O levels in English, maths, IT and science. As there is a lot of competition, it might be difficult to get in without a degree or HND. Having a strong portfolio, or experience in designing personal web pages, may make up for this.

Training

Many colleges and private training organisations are involved in the Cisco Networking Academy programme which offers certification at several levels for students and network professionals alike. Each level contains a variety of specialisms, such as networked security, telephony systems and design. As well as Windows operating systems, Linux technologies are also covered.
The three main levels of certification are listed below together with guidelines on suitable prior knowledge for entry:

• CCNA (Cisco Certified Network Associate) – although not essential, it is recommended that you have a level 3 IT qualification (such as those listed in Entry) or equivalent experience
• CCNP (Cisco Certified Network Professional) – CCNA or equivalent level of knowledge and experience
• CCIE (Cisco Certified Internetwork Expert) – this is an extremely high standard and it is recommended that you have several years' IT experience.

Opportunities

Some network managers are employed by companies that manufacture computers and associated equipment. Others are employed by companies that specialise in the supply, installation and servicing of computer networks.
Network managers also work for:

• manufacturing companies and retailers
• gas, electricity and oil companies
• financial organisations, such as banks, building societies and insurance companies
• hospitals
• educational institutions
• transport companies
• the armed forces, the Civil Service and local government
• the media industry, including newspapers, television and radio companies.
