What Is the CP-7832-PWR-SPL= and How Does It
Overview of the CP-7832-PWR-SPL= The CP-7832-PWR-...
Core Design Philosophy of FAN-2RU-PI-V2=
The FAN-2RU-PI-V2= is a redundant fan tray module optimized for Cisco’s Catalyst 9400/9500/9600 Series switches and ASR 9900 routers. This second-generation fan assembly introduces dual counter-rotating fan blades and adaptive speed control to deliver 18% higher airflow (210 CFM) while reducing acoustic noise to 55 dBA. Unlike standard fan modules, it supports hot-swappable N+1 redundancy and integrates particulate filtration for deployments in harsh environments like industrial plants or desert-edge data centers.
Technical Specifications Comparison
| Parameter | FAN-2RU-PI-V2= | FAN-2RU-PI-V1= |
|---|---|---|
| Airflow Capacity | 210 CFM | 178 CFM |
| Noise Level | 55 dBA | 63 dBA |
| Power Draw (Max) | 240W | 210W |
| Operating Temp Range | -40°C to +70°C | -25°C to +55°C |
| Particulate Filtration | Yes (MERV 8) | No |
Key innovations:
- Closed-loop thermal feedback via I2C sensors (6x per tray)
- Fan blade imbalance detection with auto-shutdown at >0.5mm deviation
- FIPS 140-2 compliant firmware for encrypted status reporting
Chassis Compatibility and Limitations
Supported Platforms
- Catalyst 9407R: Requires IOS XE 17.10+ for dynamic speed control
- Catalyst 9500-32QC: Max 4x modules per chassis (front-to-back airflow)
- ASR 9906: Must disable “fast poll” mode to prevent false alarms
Critical constraints:
- Incompatible with Catalyst 9300-48UXM due to 1RU height limitation
- Requires minimum 3000W power supply when operating at full load
- Particulate filters need quarterly replacement in ISO Class 8+ environments
Operational Best Practices
1. High-Density Data Center Cooling
In 40G/100G spine-leaf architectures, configure N+1 redundancy with staggered RPM profiles. Use show environment fan CLI commands to monitor:
- Individual fan RPM variance (<5%)
- Air intake/exhaust ΔT (<15°C)
- Cumulative runtime hours for predictive maintenance
2. Industrial IoT Deployments
For manufacturing floors with metal shavings:
- Enable filter clog detection (
hardware environmental filter-monitor) - Set aggressive cleaning cycles every 200 operating hours
- Replace filters when airflow drops below 160 CFM
3. Service Provider Edge
In 5G MEC deployments:
- Pair with CAB-AC-3000W-PI power supplies for -48VDC operation
- Disable acoustic noise reduction in environments exceeding 35°C ambient
User Concerns Addressed
Q: Can V2 fans operate in V1 chassis slots?
A: Yes, but requires Cisco TAC case escalation to disable firmware signature checks. Not recommended for FIPS-compliant networks.
Q: How to troubleshoot “Fan Redundancy Lost” alerts?
A: Follow this triage path:
- Verify
hw-module fan tray 1 statusoutput - Check rear-midplane connector pins for oxidation
- Test with reduced fan speed (
platform hardware fan speed 70%)
Q: Is liquid cooling conversion possible?
A: No. The FAN-2RU-PI-V2= uses proprietary air-channel designs incompatible with third-party liquid cooling kits.
Procurement Considerations
While Cisco officially discontinued new FAN-2RU-PI-V2= sales in Q3 2024, certified refurbished units with 90-day warranties remain available. For verified stock and bulk pricing, visit [“FAN-2RU-PI-V2=” link to (https://itmall.sale/product-category/cisco/).
The Hidden Value in Thermal Management
Having deployed these modules in Middle Eastern telecom networks, the FAN-2RU-PI-V2=’s sand filtration proves invaluable for preventing hardware failures in dust storm-prone regions. However, the 18% power consumption increase over V1 makes it less suitable for greenfield data centers prioritizing PUE optimization. For enterprises with existing Catalyst 9400/9500 investments, this fan module remains the most cost-effective path to achieving ASHRAE Class H3 thermal compliance without chassis upgrades.
