Juniper High-Capacity Fan Tray for MX480

The Juniper FFANTRAY-MX480-HC-S is a high-capacity fan tray for the Juniper MX480 Universal Routing Platform — providing the enhanced cooling airflow required for high-power MPC line cards including MPC10E and other next-generation MPCs that exceed the thermal capacity of the standard MX480 fan tray.

Key Features

• High-capacity cooling for MX480 with next-generation high-power MPC line cards
• Required for MPC10E and other high-TDP MPCs in MX480 chassis
• Hot-swap capable for non-disruptive fan tray replacement in active MX480
• Juniper-genuine for MX480 chassis airflow and thermal management compatibility
• Ensures MX480 thermal compliance for full chassis population with high-power MPCs

Product Specifications

• Part Number: FFANTRAY-MX480-HC-S
• Manufacturer: Juniper Networks
• Component Type: Fan Tray (High Capacity)
• Compatible System: Juniper MX480
• Airflow: Front-to-back (AFO) — matches MX480 standard airflow direction
• Hot-Swap: Yes

Component Specifications

• Fan Speed: Variable — controlled by MX480 chassis based on thermal load
• Acoustic: Higher operating noise vs. standard fan tray at full speed
• Redundancy: MX480 supports multiple fan trays for N+1 cooling redundancy
• Management: Chassis Environmental Monitoring via Junos OS
• Required For: MPC10E, MPC7E, and other high-power MPCs in MX480

Use Cases

• MX480 chassis upgrade to support MPC10E 100/400GbE line cards requiring high-capacity cooling
• Replacing standard MX480 fan trays when installing next-generation high-power MPCs
• Fan tray replacement for failed or degraded cooling in production MX480 chassis
• Spare fan tray stocking for MX480 deployments with strict uptime and thermal SLAs

Compatibility

• Juniper MX480 chassis only — not compatible with MX240 or MX960 fan trays
• Required when MPC10E or other high-TDP line cards are installed in MX480
• Managed via Junos OS chassis environmental monitoring (show chassis environment)
• Verify MX480 chassis revision and Junos OS version for FFANTRAY-MX480-HC-S compatibility

Frequently Asked Questions

Is the FFANTRAY-MX480-HC-S required for all MX480 configurations?

No — the high-capacity fan tray is specifically required when MPC10E or other high-power next-generation MPCs are installed. Standard MX480 fan trays are sufficient for lower-power MPC generations. Always consult Juniper's MPC thermal requirements before upgrading line cards.

Can FFANTRAY-MX480-HC-S be hot-swapped in a live MX480?

Yes — MX480 fan trays support hot-swap replacement. With N+1 redundant fan trays installed, individual fan trays can be replaced without interrupting chassis cooling or traffic forwarding, provided the replacement is completed promptly.

Does the high-capacity fan tray increase noise levels in the MX480?

Yes — high-capacity fan trays operate at higher RPM under full thermal load, resulting in increased acoustic output compared to standard fan trays. This is a consideration for deployments in noise-sensitive environments such as office-adjacent data centers.

The Juniper FFANTRAY-MX480-HC-S provides the enhanced thermal management that MX480 chassis require when populated with next-generation high-power MPC line cards — ensuring thermal compliance, chassis stability, and continuous cooling redundancy for MX480 deployments operating at 400G line rates.
