Troubleshooting  

16-1

None of the 
LEDs turn on 
when I turn on 
the Prestige. 

Make sure that the Prestige’s power adapter is connected to the Prestige and plugged in to 
an appropriate power source. Check that the Prestige and the power source are both turned 
on. 

If the error persists, you may have a hardware problem. In this case, you should contact your 
vendor. 

1. Make sure the Prestige is connected to your computer's serial port. 

VT100 terminal emulation. 

9600 bps is the default speed on leaving the factory. 
Try other speeds in case the speed has been changed. 

I cannot 
access the 
Prestige via 
the console 
port. 

2. Make sure the communications 
program is configured correctly. 
The communications software 
should be configured as follows: 

No parity, 8 data bits, 1 stop bit, data flow set to none. 

If the 10M/100M LEDs on the front panel are both off, check the Ethernet cable 
connections between your Prestige and computer. Refer to the Rear Panel and 
Connections section for details.  

Check for faulty Ethernet cables.  

Make sure your NIC (Network Interface Card) is installed and functioning properly. 

Cannot access the 
Prestige from the 
LAN.  

Check the TCP/IP configuration on your computer. Make sure that the IP address 
and the subnet mask of the Prestige and your computer(s) are on the same subnet.
