400G spine refresh for a regional colocation operator
- Colocation operator
- Southeast Asia
- Live production fabric
- Staged over one cutover window
- Fabric class400G
- Data halls2
- Link failures at cutover0
The constraint
A colocation operator needed to lift its interconnect fabric to 400G across two halls, but the original bill of materials mixed transceiver codings that would not link against the installed switch platform.
What we did
We rebuilt the BOM against the actual platform inventory, replaced the mis-coded optics with validated equivalents, checked the optical power budget for the longest inter-hall run, and staged delivery so cutover consumables landed ahead of the switch chassis.
Outcome
A single validated BOM, compatibility confirmed in writing before purchase, and staged delivery that matched the cutover sequence instead of filling the loading bay in one drop.
What was supplied
- 400G transceivers
- Inter-hall single-mode links
- Validated compatibility matrix
- Cutover consumables
