List steps for proper cable management
Honour minimum bend radius Verify cable function using cable tester Avoid laying cables across floor, use cover if necessary Avoid EMI Use plenum cable where necessary Conch cables loosely - use Velcro Leave some slack in cable runs Specify cable standards Consider using colour coding by function Keep documentation up to date and available Use cable management devices
List steps for proper device management
Maintain up to date documentation
Employ a systematic naming convention
What is the proper way of labelling?
Label ports and jacks from telecom room out using TIA/EIA 606-B
Make sure labels stick to plastic & metal
Use network diagram when labels won’t fit on devices
Include management IP and OS version on devices
Use rack diagrams
What are rack systems used for?
Meant to optimize floor space when deploying network devices
Ensures adequate space & ventilation
