CHAPTER 5: Troubleshooting
5.0 Troubleshooting
This chapter explains basic steps to take in the event of a problem with the
installation or operation of the RISC Router Expandable. If your problem is
not solved after these steps refer to the RISC Router Network Control Guide.
5.1 Troubleshooting Steps
Check for the problems with your RISC Router Expandable.
a.
With the power down, be sure the three-pronged plug is properly
connected to the AC DC port of the RISC Router Expandable.
b.
Verify that the BNC (ThinNet—blue cable), AUI (Thick Ethernet—thick
orange cable), or MAU cable is attached to the appropriate connector
on the RISC Router Expandable for LAN.
c.
Verify that the WAN cable is attached tp the WAN connector onthe
back panel of the RISC Router Expandable for WAN Operation.
d.
Verify that the WAN jumpers are correctly configured for the interface
you are using on the WAN port of the RISC Router Expandable.
e.
Is the FAULT LED on?
f.
(BNC only) Check the terminator switches on the back panel of the RISC
Router Expandable.
Check for problems with your network.
a.
Verify that the interconnecting network cables meet the IEEE standard
for cabling and Ethernet LAN and WAN.
b.
Verify the cable connection to other computers in the the network.
In a network using Thin Ethernet (BNC) cabling, check all systems
that are daisy-chained to the system your are troubleshooting.
c.
Determine whether or not your system is the only one in the network
with a problem.
If none of the steps listed above solves your problem, see the RISC Router
Network Control Guide or call your supplier.
