Shared cabinet "security"

Mistake prevention is the key.  Neatness counts.

Label everything - cubicle, equipment, cables using high quality labels that won’t fall off.  Use a meaningful labeling scheme. Label both sides of the equipment with letters large enough for everyone to read. Color coding is nice until you have dim lighting or a color-blind tech.

Separate power and data for the wired stuff.  EMI leakage is real.  Secure power cords to the equipment.  Secure cables to PDU so they don’t fall out when bumped.  Secure the cables for “wall wart” power supplies so that they do mot loosen.  Learned this the hard way after plugs vibrated or “fell” out.

If you have issues with others pugging into your power, use electrical outlet blocker plugs (baby proofing supplies) and mark them as if the outlet is broken.

Secure your data cables so that they do not block the heat exhaust of the equipment.  Use cable boots to prevent damage to cable clips, and to prevent tugging on other cables when making changes.  Don’t bend cables beyond the minimum bend radius.

You’re only as safe as the most dangerous technician that is allowed into the space.

You get some 1U or 2U cable organizers, require cables to be secured to the management, vertical cables in shared spaces are bound together by customer, color of Velcro matches color of the power cord? Blue customer, green customer, red customer, etc. Could do the cat6 patch cables that way too, but that gets lost when moving to glass or DACs.

I also know that with enough intent, someone will accomplish whatever they set out to do regarding breaking something of someone else's. My concern is mainly towards mitigation of accidents. This could even apply to a certain degree to things within your own space and your own careless techs
