The installation of the Nokia 7250 IXR-X1 involves physical mounting in a standard 19-inch rack, connecting redundant modular power supplies, and initializing the system via its internal storage or an external bootable device. As a high-density 1RU platform, it is designed for data center leaf-spine architectures and multi-access edge computing. Alcatel-Lucent Enterprise 1. Unpack and Inspect Equipment

Ensure all components are present before beginning. The standard 7250 IXR-X1 package typically includes: 7250 IXR-X1 chassis (1RU form factor). Modular Power Supply Units (PSUs) —either AC (200-240V) or DC (-48V/-60V) variants. Modular Fan Trays for front-to-back airflow. Rack-mounting kit (brackets and screws). 2. Mount Chassis in Rack

The device requires a standard 19-inch rack for installation. Alcatel-Lucent Enterprise Positioning : Place the chassis in the desired 1RU slot. nokia 7250 ixr x1 installation guide

: Use the provided mounting brackets to secure the front of the router to the rack rails.

: Ensure there is sufficient clearance at the front and rear to maintain the front-to-back airflow path required for optimal cooling. 3. Install Power and Grounding The IXR-X1 supports 1+1 power redundancy

: Connect the chassis ground lug to the rack's earth ground before applying power. PSU Installation

: Slide the modular PSUs into the rear slots until they click into place. : Connect to a 200V–240V AC power source.

: Connect to a -48V or -60V DC power source, ensuring correct polarity. 4. Connect Management and Console

The control interfaces are located on the front or rear panel depending on the specific sub-variant (e.g., X1b). Alcatel-Lucent Enterprise Console Port save /config/initial

: Connect a terminal (RJ-45 or USB) to the console port for initial local configuration. Management Port

: Connect the dedicated Ethernet management port to your Out-of-Band (OOB) management network. : The system typically boots from an internal 80GB SSD Alcatel-Lucent Enterprise 5. Perform Initial Software Boot

If the system is not pre-imaged, you must perform a manual installation or use Zero Touch Provisioning (ZTP). Manual Install

: Use a Linux machine (CentOS 7 recommended) to create a bootable SD card or USB drive with the SR Linux image

: The device can automatically get an IP address from a ZTP server and download the SR Linux image upon first boot. : If necessary, press

during startup to enter the BIOS and change the boot device to USB or SD. Nokia Documentation Center 6. Verify Installation After boot, run these validation commands: | Symptom

Check the status LEDs on the front panel to confirm successful initialization: Power/Stat : Should be solid green once the system is fully booted.

: Ensure all fan units are operational and moving air front-to-back. Nokia 7250 IXR-X1

The 7250 IXR X1 has 4 fan modules. Each fan tray is hot-swappable.
