The Catalyst 5002 dual AC-input power supplies provide system power simultaneously (load sharing). In normal operation, each power supply concurrently provides approximately half of the required power to the system. If one power supply fails, the second power supply immediately assumes full power to maintain uninterrupted system operation. Load sharing and fault tolerance are automatically enabled. Whenever possible, connect each power supply to a separate AC-input source.
The supervisor engine module front panel has two LEDs that provide power indications. The LEDs (PS1 and PS2) are described in Table 2.
| LED | Description |
|---|---|
PS1 | If the power supply associated with the PS1 AC receptacle is operational, the LED is green. |
PS2 | If the power supply associated with the PS2 AC receptacle is operational, the LED is green. |
Environmental monitoring functions constantly monitor the internal temperature of the chassis. Each power supply monitors its own voltage and shuts itself down if it detects a critical condition. These monitoring functions display alarms on the console if any of the monitored parameters exceed defined thresholds.
The processor monitors the temperature inside the module compartment, and the power supplies use the normal and critical levels (discussed below) to monitor power supply voltages. With redundant power supplies, the switch shuts down only if both power supplies shut off.
The environmental monitoring functions use three levels of status conditions to monitor the system:
