CORRECTIVE ACTION
Make sure that the ZyXEL Device's power adaptor is connected to the ZyXEL Device
and plugged in to an appropriate power source. Make sure that the ZyXEL Device and
the power source are both turned on.
Turn the ZyXEL Device off and on.
If the error persists, you may have a hardware problem. In this case, you should
contact your vendor.
1. Check to see if the ZyXEL Device is connected to your computer's console port.
2. Check to see if the communications program is configured correctly. The
communications software should be configured as follows:
• VT100 terminal emulation
• 9600 bps is the default speed on leaving the factory. Try other speeds in case the
speed has been changed.
• No parity, 8 data bits, 1 stop bit, data flow set to none.
CORRECTIVE ACTION
Check your Ethernet cable connections (refer to the Quick Start Guide for details).
Check for faulty Ethernet cables.
Make sure your computer's Ethernet Card is working properly.
Check the Ethernet LEDs on the front panel. One of these LEDs should be on. If
they are all off, check the cables between your ZyXEL Device and hub or the
computer.
Verify that the IP address and the subnet mask of the ZyXEL Device and the
computers are on the same subnet.
