What is the best way to place network equipment in a wiring closet (small organization)?

Question

Iron

Hello!
There is a switching cabinet, relatively inexpensive - Cabeus ND-05C-42U80/120-BK.
Can't figure out how to put routers in it.
So far I have settled on this scheme (by units):
2. SHKOS-M [cross-optics]
3. Huawei AR1220VW [router with optics]
4. Mikrotik CCR1009-7G-1C-1S + [router]
5. reserve for another router
6. Coordinator VipNet HW1000 [firewall]
7. Patch panel 1
8. Patch panel 2
9. D-link DGS-1210-52 [Switch 48]
10. Patch panel 3
11. Switch 24 D-link
12. Patch- panel 4
13. Patch panel 5
14. D-link DGS-1210-52 [Switch 48]
15. Patch panel 6
16. Patch panel 7
17. D-link DGS-1210-52 [Switch 48]
18. Patch panel 8 19. UBIQUITI
US-24-500W [POE switch to 24 ]
20. Patch panel 9
POE on 24 ]

24. back wall socket block

30. HPE ProLiant DL180 2U Server [Xeon 4110 Server, RAM 32Gb, p408i-a, ST2000NM0008 x6, 2supple]

32. future telephony server

38. socket block
39. Ippon Smart Winner 2000 2U [UPS]
40. reserve for ext. battery
41. reserve for ext. battery

Here I think, and connect everything or still omit the router with optics under the patch panels with switches.
And what is the best way to place patch panels for 48-port switches, as I plan, or is there still one patch panel above the switch, the second - below? I plan to crimp short patch cords for this business myself. Or is it better to use organizers?
How would you place this equipment in the cabinet and why?

Answer 1

I would start by dividing the equipment by purpose (external and internal connections).
After that, I would group the patch panels according to this feature (for example, local connections from below, external connections from above, for example). And arranged the equipment in the same way. UPS to the lowest unit. all cables from the equipment are grouped into bundles in directions, and spread along the cable channel, which is attached to the side of the rack.
Mixing equipment as you do is not very good, because during operation you may change pieces of iron, for example, for two units, and your scheme implies only one unit per direction.
Plus, the purpose of the patch panels may change, the accounting department used to sit, and now the wi-fi points.

Answer 2

A small organization with 200 links on switches? (well, in principle, whoever thinks)
IMHO, you need to start with how copper is scattered around your workplaces and from there you can see how best to group it all in a closet.
But all the same, I would put organizers between patch panels and switches, because, according to the correct links, they are made with a good margin (at least 2 ends for each seat, for each office for the maximum estimated number of seats), and switches on the move are enough only for active ones, and then in a friend who wants to put POE phones, etc., make some kind of switching between panels or put other switches
