Removing the Cooling Fan Module from the ULTRIX-FR2 Chassis

The Cooling Fan Module is critical to the operation of the Ultrix router. Should a fan fail within the module, you will

need to replace the entire module with a new one (ULTRIX-FM-NS-2RU). You will also need to transfer the Micro

SD card from the failed Cooling Fan Module to the new module.

The Cooling Fan Module is accessed via the front of the router chassis and requires that you remove the door first. The

door is secured to the front of the router chassis with a rare earth magnet on each side.

 The ULTRIX-FM-NS-2RU Cooling Fan Module is only installed in newer ULTRIX-FR2 routers.

 The Cooling Fan Module replacement should be performed while the chassis is powered on.

To remove the door from the chassis

1. Verify that the router you are using is compatible with the ULTRIX-FM-NS-2RU by ensuring that the Ultrix logo

on the front door displays an “i” with a blue dot.

2. With your left hand, grasp the top and bottom of the door at the left sides.

3. With your right hand, grasp the top and bottom of the door at the right side.

Caution — For reliable performance, the Ultrix router should not run without fans for more than 5

minutes.

ESD Susceptibility — Static discharge can cause serious damage to sensitive semi-conductor

devices. Avoid handling circuit boards in high static environments such as carpeted areas and when

synthetic fiber clothing is worn. Always exercise proper grounding precautions when working on circuit

boards and related equipment.

The ULTRIX-FM-NS-2RU is a Cooling Fan Module designed for use with the ULTRIX-FR2 router chassis. This module is critical for the operation of the Ultrix router, ensuring proper cooling and preventing overheating. It is specifically installed in newer ULTRIX-FR2 routers.

Function Description:

The primary function of the ULTRIX-FM-NS-2RU is to provide cooling for the Ultrix router chassis. It houses multiple fans that circulate air to dissipate heat generated by the router's internal components. This continuous cooling is essential for maintaining the router's performance and longevity. Should any fan within the module fail, the entire module must be replaced to ensure the router continues to operate reliably. The module also integrates with a Micro SD card, which provides system storage and a default software build, making it a crucial component for both cooling and system integrity.

Important Technical Specifications:

Module Type: Cooling Fan Module.
Compatibility: Designed for ULTRIX-FR2 router chassis.
Micro SD Card Integration: Includes a slot for a Micro SD card, which stores system information and a default software build. The Micro SD card is located between the first fan and the fan PCB within the module.
Mounting: Secured to the Main Board of the chassis with a #1 Phillips screw and connects to the backplane.
Access: Accessed via the front of the router chassis, requiring the removal of the front door.
Door Security: The front door is secured to the chassis with rare earth magnets on each side.
Cooling Requirement: The Ultrix router should not run without fans for more than 5 minutes to ensure reliable performance.

Usage Features:

Front Panel Access: The module is designed for easy access from the front of the router, simplifying replacement procedures.
Micro SD Card Transfer: A key usage feature involves transferring the existing Micro SD card from a failed module to a new one. This is critical because the Micro SD card contains vital system information and a default software build. Using an alternate Micro SD card or failing to transfer the original will result in the loss of system information and a return to factory default settings.
Hot-Swappable (Power-On Replacement): The Cooling Fan Module replacement can be performed while the chassis is powered on, minimizing downtime.
Visual Indicator: The Ultrix logo on the front door displays an "i" with a blue dot, which serves as a visual indicator for compatibility with the ULTRIX-FM-NS-2RU.

Maintenance Features:

Module Replacement: In case of a fan failure, the entire ULTRIX-FM-NS-2RU module is replaced rather than individual fans. This streamlines maintenance and ensures all cooling components are new.
Screw-Secured: The module is secured with a single #1 Phillips screw, making removal and installation straightforward.
Backplane Connection: The module connects to the router's backplane, ensuring proper power and data communication.
ESD Precautions: Maintenance procedures emphasize the importance of ESD (Electrostatic Discharge) precautions. Technicians are advised to avoid handling circuit boards in high static environments and to exercise proper grounding precautions to prevent damage to sensitive semi-conductor devices.
Comparison with New Module: Before installation, it is recommended to compare the failed module with the new replacement to ensure they have the same number of fans, preventing potential compatibility or cooling issues.
Door Alignment: Reinstalling the front door requires careful alignment to prevent damage to internal components. The door is aligned by matching the Ultrix logo and the Ross logo on the corner, ensuring the door is oriented correctly.

The ULTRIX-FM-NS-2RU is a vital component for the Ultrix-FR2 router, combining essential cooling capabilities with critical system storage via its integrated Micro SD card. Its design prioritizes ease of maintenance and reliable operation, with clear instructions for replacement and important safety considerations.
