The need
The building has eighteen floors, three tenants per floor, two access points per floor, cameras in the lobby and lift lobbies, and door controllers at every stairwell. Each of those systems arrived with its own switch, and the riser ended up with four boxes per floor and no one who could see the whole building. The landlord wanted one dashboard, per-tenant separation and a fibre link to the building core instead of copper stacking.
What was specified
| Model | Qty | Role in the project |
|---|---|---|
| RS1024K-24L-4S-10G-M3 | 3 | Riser aggregation, 24 ports with four 10G SFP uplinks to the building core |
| RS1024K-P24-4S-10G-M | 6 | Floor PoE, access points, lobby cameras and door controllers on one managed switch |
| RS1001G-1S | 4 | Legacy lift intercom and metering, single-port media conversion |
Why that split
The riser aggregation only has to move traffic between floors and the core, so a 24-port unit with 10G uplinks is enough and keeps the fibre count low. PoE belongs on the floor where the access points and door controllers are, and putting them on the same switch lets the landlord power-cycle a controller without entering a tenant suite. The lift intercom and meters are single-port, so a converter keeps them off the main switch and off the tenant VLANs.
Result
- One dashboard shows every floor, with tenant VLANs separated.
- A door controller can be restarted remotely instead of sending an engineer up the riser.
- Meter readings ride the same network without tenant data exposure.
Quantities in the table are the planned build, not a bill of materials for a specific tender.
