Enterprise UniFi console for large networks

The Ubiquiti Cloud Key Enterprise is a 1U rack-mountable console built to manage more than 1000 UniFi Network devices and over 10000 simultaneous clients. A 16-core Intel Xeon processor at 2.3 GHz, 32 GB of DDR4 ECC memory and a 256 GB M.2 SATA drive power the management plane. Redundant 550 W hot-swappable power supplies and a front-panel touchscreen complete the appliance.

Redundant power and high-speed uplink change

Two hot-swappable 550 W AC power supplies keep the unit running if one module fails. A single 10G SFP+ LAN port and a 1GbE RJ45 LAN port provide the data path, while a dedicated 1GbE management port separates control traffic. Bluetooth enables initial provisioning without a wired connection to the console.

Verify rack depth and SFP+ module compatibility

The chassis measures 787 mm deep, so confirm that your cabinet can accommodate the full length. The 10G uplink requires a compatible SFP+ transceiver, which is not included. Operating temperature range is 0 to 35 °C with 8 to 90 % non-condensing humidity, so ensure adequate airflow in the rack.

Questions about this item

How do I replace a failed power supply in the CK-Enterprise?

The unit includes two hot-swappable 550W AC/DC PSUs; slide out the faulty module and insert a replacement without powering down the appliance.

Which resource caps out first when the CK-Enterprise runs at full load?

The appliance supports 10,000 simultaneous sessions, so the session table fills before the 16-core Xeon processor or 32 GB of ECC memory become bottlenecks.

What noise and heat should I expect from the CK-Enterprise in a rack running 24/7?

Operating temperature is rated 0 to 35 °C with dual 550W redundant PSUs and forced-air cooling; fan speed scales with load, so expect audible airflow in a quiet room.
