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

: 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

If the system is not pre-imaged, you must perform a manual installation or use Zero Touch Provisioning (ZTP). Manual Install nokia 7250 ixr x1 installation guide

: 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

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 The installation of the Nokia 7250 IXR-X1 involves

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

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: Title: Step-by-Step Installation Guide: Nokia 7250 IXR X1

Service Interfaces: 4 x QSFP-DD 400GE and 32 x QSFP28/QSFP+ (100/40GE) ports.

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.

4. Initial System Startup and Configuration

Once hardware is installed, the guide moves to the software setup.

  1. Power On: Flip the power supply switches to ON. The fans should spin up immediately.
  2. Boot Sequence: Watch the LEDs on the CPM. The "Status" LED will blink during the boot process and turn solid green when the system is operational (this can take several minutes).
  3. Console Connection:
    • Connect a console cable (RJ-45 or USB, depending on the specific revision) to the Console port.
    • Use a terminal emulator (Putty, TeraTerm) with settings: 9600 baud, 8 data bits, no parity, 1 stop bit.
  4. Login:
    • Default credentials are often required. If this is a new box, it may boot into a "Zero Touch Provisioning" (ZTP) mode looking for a DHCP server, or prompt for a default login (often admin/admin or provided by Nokia).
