Cisco Systems SCE 1000 2xGBE, OL-7821-04 Refer to the following tables for LED status information

Chapter 4 Installation and Maintenance

Power Supply Overview

On both the AC-input and DC-input power supplies, the IN LED iis used to monitor the voltages received by the platform from the power source. If the input voltages are within normal operating ranges, the green IN LED is illuminated. If the input voltages are above or below normal ranges, the IN LED is not illuminated.

On both the AC-input and DC-input power supplies, the OK LED is used to monitor the power supply DC output voltages used to power the platform. The normal operating ranges for the 12 VDC output voltage is between 11.9V and 12.1V. If the output voltages are within normal operating ranges, the green OK LED is illuminated. If the 12 VDC output voltages are above (more than 12.1V) or below (less than 11.9V) normal ranges, the OK LED is not illuminated.

The Power A and Power B LEDs on the front panel indicate whether the corresponding power supply unit is functioning normally.

Refer to the following tables for LED status information

Table 4-4 IN LED Status for AC-input and DC-input Power Supply Units

LED State		Power Supply Unit Condiiton
On (green)		The input voltage is in the required range.
Off		The input voltage is not in the required range.
Table 4-5	OK LED Status for AC-input and DC-input Power Supply Units
LED State		Power Supply Unit Condiiton
On (green)		The output voltage is in the required range (between 11.9 and 12.1 VDC).
Off		The output voltage is not within the required range. (is greater than 12.1
		VDC or less than 11.9 VDC)

Table 4-6 Power LED (on front panel) Status for AC-input and DC-input Power Supply Units

LED State	Power Supply Unit Condiiton
Continuous green	Corresponding power supply unit is present and functioning normally
Red	Corresponding power supply unit present, but malfunctioning
Unlit	Corresponding power supply unit is either not present or has failed.

Note Simple Network Management Protocol (SNMP) monitors the activity of the power supplies. In most cases when a power supply problem occurs, an SNMP trap is sent in SNMP and the appropriate message is posted on the SCE 1000 CLI.
