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.

: 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 nokia 7250 ixr x1 installation guide

: 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

: 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 Installing the Nokia 7250 IXR-X1 is straightforward if

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

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 Need advanced configuration help (OSPF, MPLS, EVPN)
