Juniper Networks MX480 Enhanced High Capacity Fan Tray FFANTRAY-MX480-HC-S-A.

Model Number: FFANTRAY-MX480-HC-S-A
Part Number: 760-029685
Compatible Part Numbers: COUCAKLBAA

Features:
• High capacity fan tray containing six fans.
• The MX Series high-capacity fan trays satisfy cooling requirements for high-density DPCs and MPCs, and must be upgraded for proper cooling.
• When the router is operating normally, the fans function at lower than full speed. If a fan fails or the ambient temperature rises above a threshold, the speed of the remaining fans is automatically adjusted to keep the temperature within the acceptable range. If the ambient maximum temperature specification is exceeded and the system cannot be adequately cooled, the Routing Engine shuts down the system by disabling output power from each PEM.
