As I try to catch up and close up on my latest project, I thought I would illustrate some power no-no's.
I can't count how many times I see power strips HANGING by a power cable. COME ON PEOPLE!! Worst case scenario should be that you have to use a tie wrap or double-sided tape to attach it to the rack or shelf. i have been seen these power cable wriggle free over time.
A little trick I like to do is to tie wrap the AC cables to the equipment, when possible. That way you can't accidentally pull out a cable as you walk by or trace cables.
I use Velcro straps from the dollar store to bundle cables that belong together. For example, maybe cables from the same group on the patch panel, or switch. Make sure not to cinch the wraps too tight. Otherwise tracing them would be difficult. I also use the straps to loop around a single cable when I'm tracing a cable and it goes behind the rack. With the wrap around the single cable, I can easily find the cable on the other side.
In this case I noticed the cabling behind the rack was not supported by anything and was pulling on the cables in the punch down connectors.
So I purchased some brackets to support them. Some cables where actually pulled out from the blocks and I had to punch them down.
Just a bit of a pet peeve; when I see cables running in a cable tray above, I hate it when I see them tie wrap cables, or in this case, ran them outside the cable tray.
And of course, if you have documentation, create a policy or procedure to keep it up to date. in this example the documentation hasn't been touched since 2002.
Whew..... Now on to the router and switch configs...
