Key Features
- Model: 3AL97042AB (also labeled as DC48B).
- Type: DC power supply unit for the Alcatel-Lucent 1642EM SDH/MSTP device.
- Function: Provides -48V DC power to the 1642EM system, commonly used in telecom central offices or base station sites.
- Input Voltage: -48V DC (standard telecom power).
- Redundancy: Supports dual-power redundancy for high availability (e.g., dual 3AL97042AB units in one chassis).
- Compatibility: Designed for 1642EM subracks (e.g., 75Ω/120Ω impedance variants).
- Physical Slot: Occupies slot 6 in the 1642EM chassis.
Installation & Deployment
- Hot-Swappable: Can be replaced without powering down the entire system.
- Wiring: Requires shielded power cables and proper grounding to avoid noise/interference.
- Monitoring: Power status is visible via LED indicators (e.g., green for normal, red for fault).
Use Cases
- Telecom Access Networks: Powers 1642EM devices in metro access layers (e.g., base station backhaul, enterprise SDH links).
- Compact Sites: Ideal for space-constrained environments due to 1642EM’s small form factor.
Troubleshooting Tips
- Power Failures: Check input DC voltage and fuse integrity.
- Alarms: Use the 1320CT software to monitor power-related alarms (e.g., "PSU Fail").
- Replacement: Ensure the new unit matches impedance settings (75Ω vs. 120Ω) of the 1642EM subrack.
