Cisco Systems SCE 1000 2xGBE, OL-7821-04 manual Troubleshooting the Power Subsystem

Chapter 8 Troubleshooting

Problem Solving Using a Subsystems Approach

•When all LEDs come on to indicate that the system has booted successfully, the initial system banner should be displayed on the console screen. If it is not displayed, see Connecting the Local Console (on page 5-1) to verify that the terminal is set correctly and that it is properly connected to the console port.

•If the banner is displayed, but the Status LED is flashing orange, indicating a warning state, check the user log:

At the prompt, type: more user log

If any of the following warning messages appear, turn the SCE 1000 platform off and call technical support.

•"voltage problem:"

•"fans problem"

•"abnormal raise in interior temperature:"

If the following warning message appears, delete unneeded files from the disk.

•“insufficient disk space:”

Troubleshooting the Power Subsystem

Check the following to help isolate a problem in the power subsystem. In the normally configured SCE 1000 platform with redundant power supply units, it is unlikely that the device will not start at all. However, at startup it should be verified that both power supply units are operational, and therefore the following steps should be followed if one of the Power LEDs on the front panel remains unlit when the SCE 1000 platform is powered up.

Note If the system powers off due to an environmental shutdown, wait at least one minute before manually rebooting the system, or it will pause indefinitely.
