Testing the LAN Path to Your STM

You can ping the STM from your PC to verify that the LAN path to the STM is set up correctly.
To ping the STM from a PC running Windows 95 or later:
1. From the Windows toolbar, click Start and select Run.
2. In the field provided, type ping followed by the IP address of the STM; for example:
ping 192.168.1.201
3. Click OK. A message, similar to the following, should display:
Pinging <IP address> with 32 bytes of data
If the path is working, you will see this message:
Reply from <IP address>: bytes=32 time=NN ms TTL=xxx
If the path is not working, you will see this message:
Request timed out
If the path is not functioning correctly, you could have one of the following problems:
• Wrong physical connections
- Make sure that the LAN port LED is on. If the LED is off, follow the instructions in
LAN or WAN Port LEDs Not On
- Check that the corresponding Link LEDs are on for your network interface card
and for the hub ports (if any) that are connected to your workstation and STM.
• Wrong network configuration
- Verify that the Ethernet card driver software and TCP/IP software are both
installed and configured on your PC or workstation.
- Verify that the IP address for your STM and your workstation are correct and that
the addresses are on the same subnet.

Testing the Path from Your PC to a Remote Device

After verifying that the LAN path works correctly, test the path from your PC to a remote
device. From the Windows Run dialog box, type:
ping -n 10 <IP address>
in which <IP address> is the IP address of a remote device such as your ISP's DNS
server.
If the path is functioning correctly, replies as in the previous section are displayed. If you do
not receive replies:
• Check that your PC has the IP address of your STM listed as the default gateway. If the
IP configuration of your PC is assigned by DHCP, this information is not visible in your
PC's Network Control Panel.
