Sheet N-203-EN: Network-cabinet coordinates and the FW-08 and FW-09 front zones on X 71–107 m

What this sheet shows

N-203-EN is the deployment plan at scale 1:100 for X 71–107 m. The line under the top border states the contents: all GPU and network cabinet IDs, CDUs and fan walls (facility context), column axes, maintenance zones and section cuts. That line also states that door positions are not supplied and are not shown. The drawn row runs from R057, R058, R059 and R060 through NETB-CU15. GPU cabinets R061–R066, R067–R072, R073–R078, R079–R084 and R085–R090 sit between the network cabinets. CDU-10B, CDU-11A, CDU-11B, CDU-12A, CDU-12B, CDU-13A, CDU-13B, CDU-14A, CDU-14B, CDU-15A and CDU-15B sit on the wall side of the row. FW-08 and FW-09 are each labeled fan wall 3000×1400 (facility context), with front zone 1050 and shared use. North of Y6000, NPS-8-03, NPS-8-04, NPS-8-05, NPS-8-06 and NPS-8-07 are each marked reserved area (facility context). Column-axis bubbles read 71.8, 77.6, 83.4, 89.2, 95.0, 100.8 and 106.6, the metre axis is marked 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98, 100, 102, 104 and 106, and a graphic scale of 5 m is marked 1:100. A dashed cut lettered B at both ends is drawn at NETB-CU11 and continues through CDU-11B. This is the X 71–107 m plan in the GPU hall reference.

Where each network cabinet sits

The tables give every network cabinet on this sheet an X0–X1 in the title block's millimetres. NETB-CU10 is 73,245–74,045. NETA-CU11 starts on that same 74,045 (74,045–74,845). R061 through R066 lie between NETA-CU11 and NETB-CU11 at 78,445–79,245. The plan prints XP-11 1,800 on the open interval after NETB-CU11, and NETA-CU12 is 81,045–81,845. R067 through R072 lie between NETA-CU12 and NETB-CU12 at 85,445–86,245. NETA-CU13 starts on that same 86,245 (86,245–87,045). R073 through R078 lie between NETA-CU13 and NETB-CU13 at 90,645–91,445. The plan prints XP-13 1,800 on the open interval after NETB-CU13, and NETA-CU14 is 93,245–94,045. R079 through R084 lie between NETA-CU14 and NETB-CU14 at 97,645–98,445. NETA-CU15 starts on that same 98,445 (98,445–99,245). R085 through R090 lie between NETA-CU15 and NETB-CU15 at 102,845–103,645. The plan prints END-E 1,200 after NETB-CU15. R057 through R060 are drawn before NETB-CU10. ΔX vs previous holds -2,240 from NETB-CU10 through NETB-CU11, -1,840 from NETA-CU12 through NETB-CU13, and -1,440 from NETA-CU14 through NETB-CU15. The value changes on NETA-CU12, the cabinet after the XP-11 interval, and on NETA-CU14, the cabinet after the XP-13 interval. Note 3 states the placement rule: cabinets sit on IT support rails clear of the main-beam zone (axis ±160 mm) at every position.

Front zones and the Y chain

Front clearance is printed on each network-cabinet row. The table gives 2450 cold aisle to NETB-CU10, NETA-CU11, NETB-CU12, NETA-CU13, NETB-CU14, NETA-CU15 and NETB-CU15. It gives 1050 to FW-08 to NETB-CU11 and NETA-CU12, and 1050 to FW-09 to NETB-CU13 and NETA-CU14. NETB-CU11 and NETA-CU12 are the cabinets on either side of the XP-11 interval, where FW-08 is drawn. NETB-CU13 and NETA-CU14 are the cabinets on either side of the XP-13 interval, where FW-09 is drawn. The callout names the fan-wall case: network cabinet front zone where a fan wall faces (1,050 mm). Switch front withdrawal needs 1,000 mm and fan-wall service needs 850 mm; both use the same 1,050 mm zone and are not performed at the same time, which the sheet marks with red cross-hatch. GPU cabinet fronts keep a 1,200 mm tray-withdrawal zone, marked with orange hatch, and the callout states that fan walls do not face GPU cabinets. Note 1 is the Y chain those zones sit in: wall line Y0, wall zone Y200, CDU ≤950 to Y1150, rear maintenance 1000 to Y2150, cabinet 1200 to Y3350, then cold aisle 2450 to the fan-wall rear and column-flange line Y5800 (flange Y5825, partition axis Y6000). Note 1's cabinet 1200 ends at Y3350. The callout's 1,200 mm is the orange tray-withdrawal zone at the GPU fronts. Note 2 names the rear zone 1000, drawn as blue dots, as GPU rear access and network PSU/fan replacement from the rear. The Y scale prints 4400 between 3350 and Y6000. Y3350 plus the callout's 1,050 mm is that printed 4400, and 4400 plus the 1400 in the fan-wall label 3000×1400 is the column-flange line Y5800. The same 1,050 mm plus 1400 is note 1's 2450, the cold aisle carried to the fan-wall rear.

Status

The title block dates the sheet 2026-10-05 and issues it as Public Edition P2, number N-203-EN, sheet 11 of 30, scale 1:100, units mm. The sheet title is Deployment plan X 71–107 m. The status line reads: reference design for study and evaluation — not for construction. The header says door positions are not supplied and are not shown. Note 4 says door positions are to be confirmed, and it states that electrical-zone reserved areas north of Y6000 are facility context. On the plan those areas are the boxes NPS-8-03, NPS-8-04, NPS-8-05, NPS-8-06 and NPS-8-07. FW-08 and FW-09 are marked facility context on the fan-wall labels. The drawing is part of the Public Edition P2 network reference design.
