Network cabling- new rack

I never had the opertunity to completly rewire and set up a Rack with patch panels and new gig switches. I know the basics, and have maitained equipment already setup. My question is when cables are run and brought to the patch panels, do I wire everything into the panels and then from the patch panels to the switch?? Please refresh my memory. Ken

Thanks. We'll let you know when a new response is added.

Correcto Order of Sequence.

User NIC -> CAT? -> User Datapoint -> CAT? -> Patch Panel -> CAT? -> Switche(s)

    Cabling > Patch panel > Switch Do yourself a favor and mark/verify each cable and make up a listing of what cable plugs into what patch panel port which plugs into which switch port. Much easier to troubleshoot a problem that way. I.E. LAN Cable A32 plugs in to patch panel port 15 which is plugged into switch port 10. Cable Patch Panel Switch A32 15 10 Just a suggestion.

    Hello, Exactly. All of your data drops will run back to the patch panel where you will wire them in. Then you will connect each drop from the patch panel to your switch. Routers and servers can be directly attached to your switch. All the patch panel really does is create a central point of connectivity for your computers. In simplest terms you could run a CAT5 cable directly from the computer's NIC straight to the switch, but in an office environment this is not very practical. Note: Be sure to properly label your patch panel so you can easily match a port to a physical location. This will save you a lot of time should the need to troubleshoot a faulty connection arrise. Good luck!

    Some of the previous replies had good advice. Here's my recommendation of a short list of your steps to follow: 1. Mark each of your "station" cables before you pull them loose. Station cables are the cables going from the data room rack to the workstations (or outlets). You can get special tie wraps with a label, but don't pull the tie too tight or you will potentially mess up the cable geometry (important for 100-1000Mbps). 2. Carefully pull each cable from the current patch (and observe the amount of twisted wire that was run to each punch-down termination) 3. Install your rack, allowing space to run the old cables to the position of the new patch. NOTE: There are two wiring patterns, 658A and 658B, and BOTH ends of the station cable have to be wired to the same pattern. If you don't know which your station outlets are, try one way, and use a pair scanner to see if you were right. 4. Trim off the old portion of each cable where the wires were punched down. Terminate each station cable, in order, on your new patch, remembering to keep exposed pairs and untwist to a minimum. Properly terminated Cat 5e or Cat 6 cables will have only about 1 inch of the jacket stripped back for the exposed pairs, and each pair will remain twisted until it reaches the actual connector termination -- you don't want any more than about 1/2 inch of "untwist", and less is even better. You will need to duplicate this workmanship on each connection. If you don't feel comfortable doing this, find a professional.) 3. Mark the station locations on the patch panel. 4. Use a scanner to check out each link to the workstation, if you have any reason to think a connection may not be good. You can do a simple pair check, but make sure your checker can reveal reversals. Better cable scanners will measure the cable run for all the Cat 5e parameters, so you will know in advance if you can reliably run 100BaseT or 1000BaseT speeds. Remember, today's data speeds involve frequencies from VHF to near-microwave, and close doesn't cut it. 5. Neatness counts, and you can use cable-management trays to help route your patch cords to your switch. Best of luck.

    Just to throw in my $.02 worth. You've been given some excellent advice. My add-on..... If you re-terminate any of the cables, test each and every one of them with a cable scanner. I've encountered a number of "home-patched" (as opposed to factory-made) cables in which the wires which were not used for 10-BaseT and 100-BaseT were open, crossed, etc. This WILL BREAK 1000-BaseT - even with auto-negotiate trying to compensate. The most recent case I recall involved a wall data jack where pins 7 and 8 were reversed on one end. Until auto-negotiate was changed to force 10 MB half-duplex, the nominal speed of the connection was 100 MB full-duplex, but carrier pigeon would have been faster. Once we found that forced 10 MB worked fine, then we started looking at the cable plant and patch cords. As long as I'm on my cable rant, I also recall a case about 6 years ago where one customer was having terrible service. Turned out that the whole run was Cat5 - with the exception of a 3 foot Cat3 patch cord. The run was enough Cat5 so that the adapter and switch negotiated 100 MB, but it broke down under actual use.

    Thank you ALL for your input!!! You all have given me great advice, and I plan on incorporating this advice into my management plan. Thanks again. Coyoteken
