#ops-eqsin has a planned switch upgrade, replacing the two older Juniper switches with new Nokia switches ordered via T417350 (cables) and T414840 (switches).
Jin was on-site to install these on 2026-07-24, but the rack PDUs and cabling are in the way of installation to the point that we need to schedule downtime for the site.
The work will involve:
* Carefully unmounting the PDUs and twisting them out of the way to access the back rack rail.
* Installation of new nokia switches asw1-60[34]-eqsin into U37 in rack 60[34]
* wiring of new asw1-60[34]-eqsin to routers and msw[12].
* corrective cable auditing and patching to bring site to standard
The work will not include:
* migration of hosts from old to new switches, that will take place at a later date once new switches are fully online and accessible in their new permanent home.
* migration will be scheduled for a later site visit **after switch installation**.
Request from traffic:
* Scheduling and sign off to depool eqsin from serving traffic during the migration.
** While Jin will make all attempts to not unseat any cables, having to unmount and move the PDU towers could very easily result in a power loss event. As such, DC Ops prefers to fully depool in advance of the work to avoid negative user impact.
Confirmed Schedule: 2026-07-29 @ 23:00 GMT to 2026-07-30 @ 03:00 GMT (July 30th Singapore AM, July 29th PM for US based folks)
