I wish to answer several points here and clarify a few others:
First, let me start by saying that I'm not asking anyone to give up their job as a designer and do my work for me. I am a RCDD in training and can do my own design work (as an understudy.) I'm simply asking for any specific tips of things that did or, probably more importantly so, what did NOT work. E.g. Don't go build a huge alert board (as Charliemopps pointed out.) TheBrez also has the right idea. We will be configuring the equipment as a refresh to our other remote sites (I work for a very large company that has ~175-200 sites scattered throughout the US alone.) that will be configured and shipped back out to their respective sites.
Also, please consider that this is a configuration center of not-yet-in-production equipment and not an in-production data center or computer room.
One example of a design conflict I'm having is racks with shelves vs. tabletop space for configuring equipment. Other good suggestions so far (and thanks to all who have contributed): Raised floors are good for permanent cabling, but poor for heavy turnaround cabling. Barcode systems for organization are HUGE.
And just for those who feel I'm reaching out because I'm in over my head....well, there's probably nothing to say that would convince you otherwise, but that is not the case. I've worked a few configuration areas before and have some experience, though on the order of a few months of it rather than years.
My design, though sounding vague in text-only form, is to have essentially 3 dedicated areas for the whole space: a storage area for both received equipment not ready for configuration and empty boxes of equipment that is a work in progress, an area for unboxing/boxing the equipment with a typical shipping/receiving feel to it, and the actual configuration space. I lobbied for, and apparently won, the racks w/ shelves design (ideally each shelf representing its own TR.) Cable management is a must, of course, and thank you everyone for making that abundantly clear.
In closing, I'm just looking for those tidbits of wisdom that only come from living inside the config area and saying "Man, I really hate that we have ________."
