1U Chassis FAN Card – 1U DWDM Chassis Fan Tray
1U chassis FAN Card for DWDM systems: air outlet temperature monitoring, automatic and manual speed control and N:1 fan redundancy for up to 96 hours.
Description
Overview
The 1U Chassis FAN Card is the hot-pluggable fan unit of the 1U DWDM chassis. It sits in the subrack and moves air through the chassis to keep the cards inside their operating temperature range.
The card collects the air outlet temperature in real time, regulates its own speed and reports faults, so the chassis keeps running even when a single fan fails.
1U Chassis FAN Card Key Features
- Occupies slots 46/47 of the 1U chassis
- Real-time collection of the air outlet temperature
- Automatic speed regulation — speed follows the critical chip and module temperatures reported by the service cards, and is set to maximum if communication is lost
- Manual speed adjustment for different gear levels using various duty cycles
- Status indication — solid green for normal operation, solid red for a fault
- Electronic tag read by the host over the I2C bus, recording production date, PN/SN and runtime from power-on
- Alarm detection for communication loss, fan failure, abnormal speed and single fan stall
- N:1 redundancy — the system runs for up to 96 hours at normal temperature after one fan card fails
- Hot-plug support
1U Chassis FAN Card Specifications
Technical Specifications
| Function | Description |
|---|---|
| Occupied Slots | 46/47 slot |
| Temperature Monitoring | Temperature of the air outlet can be collected in real time |
| Automatic Speed Regulation | The fan adjusts its speed automatically based on critical chip temperatures and module temperatures reported by the service card; in case of communication loss the fan is set to maximum speed |
| Manual Speed Adjustment | Manual speed adjustment for different gear levels using various duty cycles |
| Status Indication | Solid green light indicates normal operation, solid red light indicates a fault |
| Electronic Tags | The host reads and loads the fan module electronic tag via the I2C bus; the tag records production date, PN/SN and runtime, calculated from the moment the card is powered on |
| Alarm Detection | Alarm reporting for communication loss, fan failure, abnormal speed and single fan stall |
| Fan Redundancy | N:1 redundancy enables continuous operation for up to 96 hours at normal temperature when one fan card fails |
| Hot-plug | Support |
Deployment Scenarios
- Cooling the 1U DWDM chassis with redundancy against a single fan failure
- Subracks that need real-time outlet temperature monitoring and automatic fan speed control
- Sites that want alarm reporting for fan failure, abnormal speed or a stalled single fan
- Field replacement of a fan unit without interrupting traffic, thanks to hot-plug support
