Network hardware planning: Making changes safely

Proper planning before making changes on an existing network is a necessity. Responsible VARs and SIs should have test and backout plans before going into the data center and moving switches around. From the staging process to keeping an eye on the clock during the change, the keyword is caution.

Proper planning before making changes on an existing network is a fundamental necessity. Responsible VARs and systems integrators (SIs) should have test and backout plans before going into the data center and moving switches around. From the staging process to keeping an eye on the clock during the change, the keyword is caution.

Network engineering overview: Techniques for making changes

SIs who are asked to install new hardware on their customer's network should be prepared for the possibility that their installation will go awry. Proper staging and planning can help assure a successful change.

Some important tips include:

 

  • Do as much as you can ahead of time.
  • Identify your "go/no-go" times so you can watch the clock during the change.
  • Make sure you have the tools and assistance you need to do remote configuration.
