How to Install Cisco ASR 9902 Fan Tray
- Prepare the site: Power down only the affected router module if required by your maintenance procedure, and follow all data-center safety and ESD guidelines. Ensure you have a flat, stable workspace and the proper tools for removal and insertion.
- Identify the correct slot: Locate the fan tray bay or slot designated for replacement within the ASR 9902 router. Confirm that you are working with the correct module to avoid compatibility issues.
- Remove the existing tray (if applicable): If you are replacing an existing fan tray, carefully disconnect any leading cables or connectors, release the retention mechanism, and slide the old tray out of the chassis. Keep the connectors and mounting hardware clear and undamaged for reuse if needed.
- Install the new tray: Align the new Cisco ASR 9902 Fan Tray with the slot’s guides and seating surface. Gently slide it into place until you hear or feel a secure tactile click or until the tray seats firmly against the backplane and mounting points. Reconnect any connectors exactly as they were detached, ensuring a snug, secure fit.
- Power and verify: Restore power to the router (if you had powered down the module) and observe the status indicators. Allow a brief initialization period for the fans to reach operating speed and verify that all indicators show normal operation. Confirm that temperature readings stabilize and that the system recognizes the new tray without fault.
- Post-install checks: Run a quick sanity check of the router’s environmental and performance monitoring to confirm healthy cooling. If alarms or thermal faults persist, recheck connections or consult support resources to ensure proper seating and compatibility.
Frequently asked questions
-
Q: What is the Cisco ASR 9902 Fan Tray used for?
A: It provides essential cooling for the Cisco ASR 9902 router, helping maintain stable temperatures, prevent thermal throttling, and enable uninterrupted performance during high-load conditions.
