and Terminal Emulation to VT100.

Cooling system failure
Symptom
The temperature of the firewall is higher than the normal operating temperature (40°C or 104°F).
Solution
1.
Verify that the fans are operating properly.
2.
Verify that the operating environment of the firewall has good ventilation.
3.
If the temperature of the firewall exceeds 60°C (140°F), the following alarm information appears
on the configuration terminal:
%Jun 27 11:34:39:949 2013 H3C DRVMSG/3/Temp2High:Temperature Point 0/0 Too High.
%Jun 27 11:34:42:557 2013 H3C DEV/4/BOARD TEMP TOOHIGH:
Board temperature is too high on Chassis 0 Slot 0, type is RPU.
4.
Use the display environment command to examine whether the temperature of the firewall keeps
rising. If the temperature exceeds 90°C (194°F), power off the firewall immediately and contact
your local sales agent.
Software loading failure
If software loading fails, the system runs the software of the previous version. To troubleshoot the software
loading failure:
1.
Verify that the physical ports are correctly connected. If the cable of any port is not connected,
re-connect the cable to the port, and make sure that the physical connection is correct. Then,
perform software loading again.
2.
Check for errors in the software loading process displayed on the HyperTerminal. If errors exist,
correct them, and perform software loading again.
For example, the software loading failures might occur in the following cases:
