FFANTRAY-MX480-HC-BB - MX480 High Capacity Fan Tray | Juniper
MPN： FFANTRAY-MX480-HC-BB ✓ 啟用中FFANTRAY-MX480-HC-BB 概覽
A fan tray is an electromechanical cooling subsystem - part of the broader thermal management hierarchy that spans fans, blowers, heatsinks, and airflow management within networking hardware. In carrier-class edge routers such as the MX480, the cooling system (fan tray plus air filter) works as an integrated unit to keep all line-card, switching-control, and power-supply components within their acceptable operating temperature range.
Key characteristics of the FFANTRAY-MX480-HC-BB include its six-fan configuration for high airflow, its high-capacity rating that satisfies the cooling requirements of high-density DPC (Dense Port Concentrator) and MPC (Modular Port Concentrator) deployments, and its front-accessible vertical installation at the rear of the chassis for simplified serviceability. The high-capacity designation distinguishes it from lower-airflow fan tray options, supporting fully populated MX480 configurations used in service provider and data center environments.
Because the fan tray is a field-replaceable unit (FRU), it can be hot-swapped during maintenance windows without powering down the router, and the Juniper MX480 chassis management system monitors fan tray status and airflow. The companion polyurethane air filter should be inspected and replaced periodically to maintain cooling efficiency.
Typical deployments include service provider edge and broadband multiplay gateways, high-speed VPN and business Ethernet transport, data center interconnect, campus core routing, and mobile service core applications where the MX480 is configured with high-power MPC line cards that demand maximum cooling capacity.
Design and maintenance consideration: always pair the high-capacity fan tray with a clean air filter, and verify that the MX480 chassis configuration (DPC/MPC mix) actually requires high-capacity cooling - lower-density configurations may be adequately served by the standard fan tray option. Store spare polyurethane filters at 40-80% relative humidity and 4 C to 32 C per Juniper documentation.

典型應用
FFANTRAY-MX480-HC-BB 適用於 6 應用s: Service Provider Edge Routing, Data Center Interconnect and Cloud, Broadband Multiplay and Residential Services, Mobile Service Core, Enterprise Campus Core and VPN Transport, Cable and High-Speed Transport Networks.
Service Provider Edge Routing
The MX480 is Juniper's Ethernet-optimized edge router for carrier-class Ethernet routing and high-speed transport, and the FFANTRAY-MX480-HC-BB is the cooling FRU that keeps it running in these demanding deployments. Provider edge configurations typically combine multiple MPC line cards with dense 10G/40G/100G ports, producing heat loads that only the high-capacity six-fan tray can safely manage. The fan tray, installed vertically in the rear of the chassis with its air filter, maintains component temperatures within the acceptable operating range, and its chassis-manager integration allows the router to alarm and throttle before thermal limits are exceeded, protecting revenue-bearing edge services such as VPN and broadband multiplay.
推薦
Data Center Interconnect and Cloud
In cloud, campus, and data center applications, the MX480 provides sufficient system capacity for high-density aggregation and interconnect, per Juniper and MLCP product documentation. These environments run continuously at high utilization, making sustained cooling capacity essential rather than optional. The FFANTRAY-MX480-HC-BB's six-fan high-capacity design supplies the airflow needed for fully populated MPC configurations used in data center peering and cloud edge points of presence. Because the fan tray is hot-swappable, data center operators can rotate or replace fan trays and air filters during maintenance windows without taking routing capacity offline, and the rear vertical mounting simplifies service in racked deployments.
推薦
Broadband Multiplay and Residential Services
The MX480 enables next-generation broadband multiplay services, delivering residential and business solutions from a single edge platform. Broadband subscriber deployments concentrate thousands of sessions on dense line cards, and the resulting thermal load scales directly with subscriber density. The high-capacity FFANTRAY-MX480-HC-BB satisfies the cooling requirements of these high-density configurations where a standard fan tray would leave insufficient thermal margin. Juniper's cooling system documentation notes that the fan tray and air filter work together to keep all router components within the acceptable temperature range, which is critical for always-on residential services where unplanned thermal shutdowns directly impact subscriber SLAs.
推薦
Mobile Service Core
The MX480 supports mobile service core applications, aggregating backhaul traffic from cellular networks where availability targets are stringent. Mobile core sites frequently run high-power MPC line cards to terminate high-speed backhaul, making the high-capacity fan tray a required rather than optional configuration element. The FFANTRAY-MX480-HC-BB's monitored, field-replaceable design lets operators detect fan degradation early through chassis management alarms and replace the tray proactively. Pairing the tray with a regularly maintained polyurethane air filter preserves airflow efficiency over time; Juniper specifies filter storage at 40-80% RH and 4 C to 32 C to keep spare filters serviceable for their full two-to-five-year shelf life.
推薦
Enterprise Campus Core and VPN Transport
Enterprise networks use the MX480 for campus core routing and high-speed VPN services, including business Ethernet transport. Enterprise deployments that consolidate routing, firewall, and aggregation functions on dense MPC cards benefit directly from the high-capacity fan tray's extra airflow headroom, especially in sealed or high-ambient-temperature wiring closets where cooling margins are naturally thin. The FFANTRAY-MX480-HC-BB installs vertically at the rear of the chassis, keeping the front accessible for line card service by enterprise network staff. Its status monitoring through the MX480 chassis manager gives operations teams visibility into cooling health without external environmental monitoring hardware.
推薦
Cable and High-Speed Transport Networks
Cable operators deploying the MX480 for high-speed transport and converged cable access rely on the high-capacity fan tray to handle the thermals of densely populated chassis in regional headends. Headend environments rack MX480 systems side by side, and the rear-mounted FFANTRAY-MX480-HC-BB exhausts air without recirculating heat into adjacent chassis intakes when rack airflow is properly planned. The six-fan HC design provides redundancy margin against single-fan degradation, and the chassis management system alarms on cooling shortfalls. Keeping genuine Juniper air filters on hand - stored within Juniper's specified humidity and temperature ranges - ensures replacements are effective when filters are serviced during scheduled headend maintenance.

主要差異化特點
- High-capacity airflow for dense line cards (對比FFANTRAY-MX480-BB)
- Identical hardware as a dedicated spare SKU (對比FFANTRAY-MX480-HC-S)
- Genuine Juniper chassis management integration (對比FFANTRAY-MX480 (aftermarket/surplus listings))
設計說明
Verify that the MX480 configuration genuinely requires high-capacity cooling before specifying the FFANTRAY-MX480-HC-BB. High-density MPC line card mixes demand HC airflow; low-density DPC-only configurations may be adequately cooled by the standard FFANTRAY-MX480-BB fan tray at lower cost. Per Juniper's MX480 cooling system documentation, the fan tray and air filter work together to keep all components within the acceptable operating range, so undersizing the fan tray risks thermal alarms and potential throttling on fully populated chassis.
Do not neglect the air filter. The polyurethane filter paired with the fan tray directly determines airflow efficiency; a clogged or degraded filter can negate the high-capacity tray's extra cooling margin. Juniper's maintenance documentation states the filter shelf life is two to five years depending on storage, and that if the material flakes or becomes brittle when rubbed or deformed, it is no longer serviceable. Store spare filters wrapped in plastic at 40-80% relative humidity and 4 C to 32 C in a dark environment.
For spare-parts planning, note the SKU distinction: FFANTRAY-MX480-HC-BB is the base bundle configurable option, while FFANTRAY-MX480-HC-S is the identical hardware sold as a spare. Ordering the correct SKU avoids procurement friction - site-add configurations typically use the BB option, while maintenance stock should use the HC-S spare SKU. Several distributors list stock as call-for-availability, so secure the replacement tray before scheduling a fan tray replacement window on a production router.
