Garbled terminal display
Symptom
Terminal display is garbled.
Solution
To resolve the issue:
1.
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.
When you modify the settings for the console port of the gateway, configure the same settings
for the console terminal.

If the issue persists, contact H3C Support.
Power supply system failure
Symptom
The power LEDs are off or not green.
Solution
To resolve the issue:
1.
If the DC LED is orange, the power supply has transitioned to the over-temperature protection
state. Examine the cooling system for inadequate ventilation, and make sure every empty slot is
covered by a blank filler panel.
2.
If the DC LED is red, the power supply has transitioned to a self-protection state because of a
power supplying problem. Examine the power supply for output short circuit, output
over-current, output over-voltage, input under-voltage, or remote disconnection.
The DC LED also turns red if the input of the power supply is disconnected while the other
power supply is operating correctly. In this case, connect the input or keep the input
disconnected as needed.
3.
Examine the power cord connections. If a power cord is loose, re-install the power cord. If a
power cord is broken, replace it.
4.
Examine the power module installation. If the power module is not fully seated, re-install the
power module to ensure that it has a close contact with the backplane of the gateway.
5.
Verify that the power supply system operates correctly and provides a normal voltage.
6.
If the gateway has empty power module slots, remove the power module, install the power
module into an empty power module slot after all LEDs on the power module are off, and verify
that the power module can operate correctly.
7.
Install a new power module of the same model into the same slot, and connect it to the same
power input end. If the new power module can operate correctly, the old power module has
failed. You must replace the old power supply.
8.
If the issue persists, contact H3C Support.
