Before installing any barcode system, the two things which should be kept in mind are expansion and reliability.
Ensure that company’s future needs are also fulfilled while estimating its current needs. A system should not be installed which will not be able to expand in the future. In particular, the factors to be considered are:
- Extra Terminals or stations: Install more RAM and a greater hard drive than presently required. Addition of new terminals or workstations should be available.
- Wiring: Wiring for additional workstations can generally be included when the cabling is stretched with basically no additional costs. Ensure that there is provision for some extra cables.
- Network Length Limitations: Many networks will have a limited length for the entire cable making up the network. A network which will not have provision of some extra terminals to be added easily should not be selected.
- Speed: A computer or terminal, which has the provision for upgradable speed should be selected. Ensure that best disk cache is used, and data should not be saved on RAM.
- Power Supply: Make sure that each workstation will have a reliable power source. In many cases, any convenient power outlet can be used. In industrial situations, it is consistently a good idea to build up a surge suppressor to the equipment at installation.
- Backup Hardware: As a system is combined with an operational process, it will slowly become more risky. It will be beneficial to have backup hardware in the facility to handle some inevitable failures.
- Utilities: When a system is installed, diagnostic and troubleshooting utilities must be included to handle irresistible problems. Some disk and virus-detection utilities should also be included to eliminate virus attacks.
