Reference Guide for the Model RM356 Modem Router
10-2 Troubleshooting
• Connected hub or workstation
Make sure that the connected hub or workstation is powered on.
• Ethernet cable
If you are connecting the router LAN port directly to a workstation or to the uplink (MDI) port
of another hub, use a standard straight-through Ethernet cable such as the one provided.
• Connection to another hub
If you are extending your network by connecting the router to another hub, verify that you are
using the correct combination of cable and port. If you are connecting a LAN port of the
Model RM356 Modem Router to the uplink (MDI) port of another hub, use a standard
straight-through Ethernet cable such as the one provided. If there is a switch associated with
the uplink port of the connecting hub, make sure that the switch is in the uplink (MDI)
position. If you are connecting a LAN port of the Model RM356 Modem Router to a normal
(MDI-X) port of another hub, you must use a crossover cable.
Troubleshooting a TCP/IP Network Using a Ping Utility
Most TCP/IP terminal devices and routers contain a ping utility that sends an echo request packet
to the designated device. The device then responds with an echo reply. Troubleshooting a TCP/IP
network is made very easy by using the ping utility in the built-in Manager interface (Menu 24.4)
or in your PC or workstation.
Testing the LAN Path to Your Router
To verify that the LAN path to your router is set up correctly, from the Windows 95
(or Windows NT
® ) Run menu, type Ping and the IP address of the router. Press the Enter key.
You should see a message like this one:
Pinging <IP address> with 32 bytes of data
If the path is working, you see this message:
Reply from < IP address >: bytes=32 time=NN ms TTL=xxx
If the path is not working, you see this message:
Request timed out
