Fan failure

You can look at the system status LED and the seven-segment LED of an S5120-EI switch to identify a fan

failure. If both LEDs are behaving as described in Table 6, a f

an failure occurs.

Table 6 Fan failure LEDs description

LED Mar

State

System status LED PWR/SYS Steady red

Seven-segment LED Unit

The LED flashes F for fan failure.

The S5120-EI Switch Series uses built-in fans. If a built-in fan failure occurs, contact your H3C sales agent

or service engineer for assistance and do not attempt to fix the problem yourself.

NOTE:

To ensure normal operation of the switch, contact the local sales agent or service engineer as soon as

possible when a built-in fan failure occurs.

Configuration terminal problems

If the configuration environment setup is correct, the configuration terminal displays booting information

when the switch is powered on. If the setup is incorrect, the configuration terminal would display nothing

or garbled text.

No terminal display

If the configuration terminal displays nothing when the switch is powered on, verify that:

• The power supply is normal.

• The console cable is correctly connected.

• The console cable has no problem and the terminal settings are correct.

Garbled terminal display

If terminal display is garbled, verify that the following settings are configured for the terminal, for

example, HyperTerminal:

• Baud rate—9,600

• Data bits—8

• Parity—none

• Stop bits—1

• Flow control—none

• Emulation—VT100
