Following a quick review of the photo, my professional critique of the installation is as follows:
FAIL
1 Side vents are 50% obstructed by mounting brackets on open side.
Comment: Rack, shelving modules should have been employed instead of mounting brackets.
Already discussed and picked apart. Thanks for coming late to the party *golf clap*.
2 Side vent between units appears fully obstructed (Rack to Rack)
Comment: Poor design, lack of knowledge and planning.
Look closer, there is an air-gap.
3 Bottom Unit in rack 1 is not readily accessible ~the unit above it must be removed to service the bottom one. (We don't put units on the bottom... (Dirt, physical damage, et cetera) start from top down.
Comment: Poor design, lack of knowledge and planning. Guess there is a first time for everything...
Yes it is. Again, look closer, the lowest unit is raised. You can tell by the shadow under the rear corner.
4 Rack density does not permit ventilation between units, again amateurish and problematic lending to sever thermal issues down the road that will undoubtedly require considerable configuration. Problem will likely present when they continue to fill the racks if they follow the same installation format.
Guy, you need to get your eyes checked. Only the first rack is secured. The rest are floating.
For what its worth, this photo may be old ~except for the end rack units, the rest are not aligned or properly secured, looks like it may have been taken during the build itself.
Then what is the purpose of your "professional critique" of the installation?
You sound a lot like our old friend Bargraphics.
