SWITCH MONITORING AND
6 MAINTENANCE
Monitoring the Switch Although the Switch 8800 Family has undergone a comprehensive and strict factory test before delivery, there might be some fault occurring due to improper installation. This chapter describes how to troubleshoot the Switch 8800 Family.
Troubleshooting Console If the system is normal after the Switch is powered on, the booting information Terminal will be displayed on the Console terminal. If the configuration system has failed,
the Console terminal may give illegible output or nothing at all.
1The terminal gives no displays after the Switch is powered on. In this case, you should check if:
■The power system is working normally.
■The fabric is working normally.
■The Console cable has been connected to the Console port on the fabric.
If no problem has been found in the above checking, the symptom is very likely caused by the errors listed below.
■The Console cable is not connected to the right serial port, that is, the port in use is not the one configured on the terminal.
■There are Console terminal parameter errors. (According to the parameter setting requirements, you should set the baud rate to 9600, data bits to 8, parity to None, stop bits to 1, flow control to None, and select VT100 as terminal emulation.)
■The Console cable is not in good condition.
2The terminal gives illegible characters.
This symptom is very likely caused by a Console terminal setting error. In this case, check that you have set the baud rate to 9600, data bits to 8, parity to None, stop bits to 1, flow control to None, and select VT100 as terminal emulation.
Troubleshooting PSU
Table 73 Description of the LEDs on PSU
LED | Description |
|
|
INPUT | It keeps ON if the power input is normal and the PSU switch is at ON position. It |
| keeps OFF if the power input has failed or if there is no power input at all. |
OUTPUT | It keeps ON if the power output is normal and OFF in any other cases. |
FAIL | It keeps ON if the PSU has failed and OFF in any other cases. |

Following are the PSU faults that likely appear and the methods used for problem isolation.
