  1. Some advice on cabling on the boards (thread on
  2. redbrick.computing.networking, July 2005, contributors: atlas, phil,
  3. colmmacc, drjolt, cambo):
  4. * Label both ends of every cable with source and destination (buy a
  5. labeller!)
  6. * if the source or destination change, update/replace the label with
  7. the new info.
  8. * Colour co-ordinate the cables (e.g. grey for
  9. servers-\>patch_panels, green for uplink, blue for phone cables)
  10. * Use cable ties (preferably of re-adjustable size: e.g. velcro strap
  11. ones that can be adjusted)
  12. * Run cables in bunches (e.g. run cables up side of cabinet, rather
  13. than out in the middle of the cabinet)
  14. * Buy your cables, don\'t make them
  15. * They come in half-metre increments from decent suppliers
  16. * They\'re worth about a euro, rather than 5 minutes of your time
  17. (which is worth more!)
  18. * Check they conform to Cat5e or Cat6 standards
  19. * Some places may offer the batch of cables for free if you find a
  20. faulty cable in it!
  21. * They\'re crimped by a machine in a sealed environment (minor
  22. capacitance on RJ45 head, copper pairs almost exact length)
  23. * There can be some issues with hand-made cables on GigE networks,
  24. with special multimedia stuff
  25. * Can optionally get the cables certified by someone after you
  26. have installed them
  27. * Always test crimped cables if you insist on making them yourself -
  28. don\'t rely on a wire-map tester - a proper cable tester can
  29. diagnose more problems (location of breaks, damaged cables, etc)
  30. * if you see a cable that hasn\'t been run correctly, run the cable
  31. you need to run properly so it\'s easier to remove/fix the
  32. incorrectly run cable at a later date.
