I agree as well that it's best to consult directly with the property's local inspectors, just to be on the safe side. :thumb:
Just wanted to add that this is a great topic, Mike. I saw your post this morning, and have been digging thru the NEC, FCC Part 68, and others just to see what I could find as well. The only true reference that I could locate in writing (other than in many College and University locally enforced codes) was in ANSI/TIA/EIA-942 [Telecommunications Infrastructure Standard for Data Centers]
Here's the copy and pasted reference:
Hot and Cold Aisles
Cabinets and racks shall be arranged in an alternating pattern, with fronts
of cabinets/racks facing each other in a row to create “hot†and “cold†aisles.
Cold aisles are in front of racks and cabinets. If there is an access floor, power
distribution cables should be installed here under the access floor on the slab.
Hot aisles are behind racks and cabinets. If there is an access floor, cable trays
for telecommunications cabling should be located under the access floor in the
hot aisles. A minimum of 1 m (3 ft) of front clearance shall be provided for installation
of equipment. A front clearance of 1.2 m (4 ft) is preferable to accommodate
deeper equipment. A minimum of 0.6 m (2 ft) of rear clearance shall
be provided for service access at the rear of racks and cabinets.
A rear clearance of 1 m (3 ft) is preferable. Some equipment
may require service clearances of greater than 1 m (3 ft).
Unfortunately, I'm unable to post the link here, due to it containing parentheses; so I've sent the link to your email.
It's always best to check and confirm with the local inspectors.
Big Congrats on the install! :thumb:
