Rack Layout

Rack: Eastrexon 15U Open Frame — 19.7"L × 18.8"W × 32.3"H, wall-mountable with swivel casters. Open-frame means front and back rails are populated independently except where a full-depth shelf spans both — this is why the layout below is two columns instead of one.

Current Layout (confirmed post-move)

Below the rack-mount holes: the CyberPower UPS sits on the rack's own base tray, above the caster/wheel space — not floor-standing, not rack-mounted either.

Bottom to top, by bolt-hole count:

                  Dell Precision 3620 (Proxmox)
                  full-depth shelf, 15 holes — shared front+back
        ────────────────────────────────────────────────────────
BACK RAIL                                  FRONT RAIL
Acer Aspire                                HP laptop
half-depth shelf, 3 holes                  half-depth shelf, 3 holes
(overlaps the front shelf's height         (overlaps the back shelf's
 by 2 holes)                                height by 2 holes)
5 empty holes                              10 empty holes
dell-mini + switch (TL-SG108E)             GL.iNet Flint 2 router
short shelf, 3 holes                       short shelf, 3 holes
8 empty holes                              (nothing else on front)
PDU (VEVOR, plugs facing inside)
Patch panel (Cable Matters 12-port), directly above the PDU

On top of the rack frame (not rack-mounted), front side: Lenovo ThinkPad Mini Dock 3 + Lenovo ThinkPad T420 + a TP-Link router — this TP-Link is the same unit documented as iot-ap in devices/README.md (VLAN 30 dumb AP), not a separate device.

Not in the rack at all (desk equipment, out of scope for this doc): the 3× Raspberry Pi 3B, and the mobile/personal devices and other laptops not listed above.

Cable Plan

The patch panel is mounted but unused (confirmed 2026-10-08) — every device patches directly into the TL-SG108E. Port-by-port assignments and VLAN membership live in the switch port table in networking/README.md. Revisit this section if runs are ever moved onto the patch panel.

Notes

  • The Eastrexon is an open-frame rack — no side panels, and since front and back rails are independent, front/back device counts don't need to match (confirmed here: back rail is fuller than front).
  • Swivel casters make repositioning easy but ensure they're locked when the rack is in its final position.
  • The UPS's base-tray placement keeps it clear of the casters without taking up rack-mount holes.
