Purchase Contract & Maintenance Agreements

A purchase contract determine the responsibilities of each member of the contract.  When negotiating a contract with a vendor you should always have a lawyer review it whenever possible.  You also want to make sure the contract is fair to both parties involved.   There are a few things that should be included in the contract.

  • Be specific about what hardware/software you need for the network.

  • Set up a payment schedule.

  • Cleary decide on what needs to be complete before the work is considered "finished". 

  • Penalty clause, what actions will be taken if the work isn't complete by the time specified in the contract.  For example, you might charge a company $100 a week per week they are past the due date.  This usually is frowned on and is usually not included.

Once the network is in place you may want to purchase a maintenance agreement with the provider of your hardware or software.  This agreement will give you upgrades to the system and should provide a preventative maintenance system for hardware.  If your organization is large enough you may provide this service internally.  Either way there should be a system to maintain the hardware and software.  The installation of a network is expense and needs to be kept up.

Installation Tasks

Installing a new network is a big project and should be fully planned before started.  Their are many steps that need to be completed towards the final goal.  I always recommend a test environment before you install your network, so you know what you are getting into.  Below is a list of the tasks that need to be completed:

  1. Documentation: This states what kind of network you choose, and why.  This will also outline the remaining steps involved and explain any reasons you decide to do certain things.  i.e. why did you decide to provide wireless LAN access in the hotel lobby.

  2. Site planning: This step involves blueprints of the site and states where you are going to run cable, have wiring closets, place servers etc.  A lot of thought and consideration goes into this plan.  You want to put devices where they make sense.  You wouldn't want to place all your server equipment in a room without power.

  3. Medium installation:  With a wireless solution this step becomes very easy.  With cables you have to determine how your are going to run the cables, thru walls, ceilings, or floors.  Once you have that decided you want to make sure follow all rules for the cable type you are pulling.  For example you don't want to run CAT V over florescent lights.

  4. Hardware installation: This includes setting up severs, adding NIC's (Network Interface Cards) to client computers, and upgrading client's hardware.  Some of the client hardware that may need to be upgraded are the RAM and the hard disks.  In some cases the client computer will have to be replaced if it doesn't meet the minimum requirements for the LAN OS.

  5. Software installation: The software that needs to be installed can be broken down into three phases, LAN OS software, application software, and utility software.  The LAN OS server software needs to be installed on the server(s) and can be difficult if you never have done it before.  Once complete you can then install the LAN OS client software on the client computers.  This will allow the client computers to "talk" with the server software.  Then you would install the applications that would be used by the clients on either their computer or the server or both depending on the application involved.  Finally you would install any utility software such as a virus protection program.

  6. Conversation and data preparation: With a new LAN you may have to manually enter data in from the old paper system.  If you are upgrading a preexisting LAN you may be able to convert your data to the new system.  Then you must decide what data is public and what is private.

  7. Creation of the operating environment: Set up users and groups (covered in Chapter 10)

  8. Testing and acceptance: Once you are at this step you will test the network and make sure everything works the way you expect it to.  You will test the performance to make sure it performs the way it should. 

  9. Cutover: Roll the network into a live environment.  At this stage you should try to maintain the old system as well as the network for predetermined grace period.

  10. Training: This is one of the most difficult and important steps.  This is where you have to train users on the new system.  You may find resistance in some users because people fear change.  But you should always be positive and let them know the benefits of the new system.  Your job as administrator means you need the most training.  You will be the solution provider for the users.  You will always have to stay on top of new technology and remember this is a fast changing profession.
