Cooling system failure
Symptom
The temperature of the firewall is higher than the normal operating temperature (45°C or 113°F).
Solution
To solve the issue:
1. Verify that the fans are operating correctly.
2. Verify that the operating environment of the firewall has good ventilation.
3. If the following alarm information is generated, the temperature of the firewall has reached the
warning-level high temperature alarm threshold.
%Aug 28 20:02:59:085 2021 H3C DEV/4/TEMPERATURE_WARNING: -Context=1; Temperature is
greater than the high-temperature warning threshold on slot 1 sensor outflow 1. Current
temperature is 58 degrees centigrade.
Use the display environment command to examine whether the temperature of the
firewall keeps rising. If the temperature has reached the alarming-level high temperature alarm
threshold, power off the firewall, and contact your local sales agent. If the temperature has
reached the shutdown-level high temperature alarm threshold, the device will shut down
automatically.
Information about the firewall temperature in the
display environment command output
varies by firewall model.
4. If the issue persists, contact your local sales agent.
Software loading failure

the software loading process displayed on the HyperTerminal for configuration errors. The
following errors can lead to software loading failure.
When XMODEM is used to load software, a baud rate other than 9600 bps is selected, but
the baud rate for the HyperTerminal is not reset.
When TFTP is used to load software, an incorrect IP address, software name, or TFTP
serve path is configured.
When FTP is used to load software, an incorrect IP address, software name, username, or
