Keep your network running smoothly even when the heat rises – the Cisco A903-FAN-E Cooling Fan Module delivers reliable, high‑performance cooling that protects your ASR 903 router from overheating, ensuring uptime when you need it most.
Cisco A903-FAN-E Cooling Fan Module – ASR 903 Series
This fan module fits the single fan tray slot in every ASR 900 Series router. It houses redundant fans so the system stays operational even if one fan fails, giving you peace of mind and continuous service.
The design supports hot‑swap replacement, allowing you to change the tray without shutting down the router. Just be aware of the ambient‑temperature time limit for re‑insertion, which is built into the system to protect hardware.
An optional field‑serviceable dust filter can be added, but note that it slightly reduces cooling capacity. For high‑throughput configurations with RSP3C or 40G+ modules, consult your account team to confirm temperature margins.
Benefits
- Redundant fans maintain operation after a single fan failure.
