The Nokia 7250 Interconnect Router (IXR)-X1 is a high-density, compact 1RU platform designed for multi-terabit interconnectivity in data centers, WANs, and 5G edge computing nodes. With a full-duplex capacity of 4.8 Tb/s, the
serves as a critical leaf node or aggregation point for high-performance networks. Hardware Installation Prerequisites nokia 7250 ixr x1 installation guide
Before beginning the physical installation, ensure the environment meets the following standard requirements for the Nokia 7250 IXR-X series: Rack Space: 1RU (standard 19-inch rack).
Operating Temperature: 0°C to +40°C (+32°F to +104°F) sustained. Humidity: 5% to 95%, non-condensing. Power Feeds: Dual redundant Power Supply Units (PSUs). AC Option: 200 V AC to 240 V AC (rated), 50/60 Hz. DC Option: -48 V DC to -60 V DC.
Airflow: Front-to-back or back-to-front, depending on the specific modular fan units installed. Physical Installation Steps 1. Mounting the Chassis 7250 IXR-X1 is designed for 4-post or 2-post rack mounting.
Attach the provided mounting brackets to the sides of the chassis.
Slide the unit into the rack and secure it with appropriate screws.
Ensure that the honeycomb mesh air intakes remain unobstructed to maintain EMI isolation and optimal cooling. 2. Grounding the System The X1 is 1RU high and supports front
Always connect a grounding cable to the designated grounding lug on the rear of the chassis before applying power. This is vital for safety and to protect the high-performance ASICs from static discharge. 3. Powering the Router
supports concurrent use of AC and DC power supplies for maximum flexibility.
Insert the modular PSUs into the rear slots until they click into place.
Connect the power cables to both feeds to ensure 1+1 redundancy.
Verify the status via the Power Status LEDs on the front panel. 4. Network and Control Port Connections features a high-density port layout:
Service Interfaces: 4 x QSFP-DD 400GE and 32 x QSFP28/QSFP+ (100/40GE) ports. Expected: Both PSUs showing oper-status: up set /
Transceivers: Supports flexible optical breakouts including 4 x 100GE, 2 x 100GE, and 4 x 25GE/10GE options.
Control Interfaces: Connect to the Console or Management ports for initial configuration. The unit also includes a USB port and an SD slot for storage. Software Boot and Initial Commissioning 7250 IXR-X1
typically boots the Nokia SR Linux or SR OS from an internal SSD.
Zero Touch Provisioning (ZTP): The system supports ZTP for automated deployment. Upon first boot, the router can automatically pull configuration and image files from a network server.
Manual CLI Setup: Access the Nokia MD-CLI through the console port to manually configure IP addresses and routing protocols.
