Installation Guide for the Nokia 7250 IXR-X1 The Nokia 7250 IXR-X1 is a high-performance, 1RU (Rack Unit) interconnect router designed for high-density 10GE to 400GE aggregation in data center and 5G networks. This guide provides a summary of the physical installation and initial setup procedures. 1. Site Preparation and Safety
Before installing the chassis, ensure the environment meets the following requirements: Space: Reserve 1RU of space in a standard 19-inch rack.
Cooling: Ensure clear airflow for the three modular replaceable fans. The system supports both front-to-back and back-to-front airflow options.
Temperature: Maintain a sustained operating temperature between 0°C to +40°C (32°F to +104°F).
Safety: Always use qualified personnel for installation to prevent equipment damage and voiding warranties. 2. Physical Installation
Unpack and Inspect: Check the chassis and components for any shipping damage.
Mounting: Secure the rack-mount brackets to the chassis. Install the router into the rack and tighten the screws.
Grounding: Connect the chassis to the rack’s ground according to local electrical codes. 3. Power and Cabling The 7250 IXR-X1 supports redundant power configurations: Power Options: HV AC: 200V AC to 240V AC (50/60 Hz). DC: -48V DC to -60V DC.
Data Cabling: Connect optical fibers to the appropriate ports. The IXR-X1b variant typically features 12 x 400G QSFP-DD and 24 x 100G QSFP28 connectors.
Control Interfaces: Connect to the console, management, or USB ports as needed for initial configuration. 4. Software Boot and Initialization nokia 7250 ixr x1 installation guide
The system typically runs Nokia SR Linux or SR OS, booting from an internal SSD.
Initial Boot: Power on the chassis. The system will boot the pre-installed image from the internal storage.
Manual Boot (Recovery): If a manual bootstrap is required, you can use a recovery SD card or USB device to boot the system into the BIOS and select the appropriate boot source.
Management: Initial access is gained via the Console port (typically RJ-45) to perform basic system configuration, such as setting management IP addresses.
