If There is a Problem:
Troubleshooting the EtherPath SS-R1 Nailed-Up Configuration
Introduction
At this point, a pair of EtherPath units should have been configured and a link established that
allows a pair of PCs to communicate with each other's terminal screens via the Ether Paths just
as if they were directly connected with a null modem cable. If it has not been possible to get a
similar result, check for the possible problems described below.
P:
Web browser not connecting during the EtherPath configuration.
S:
To
verify the
physical connection
, check that:
●
A faulty ethernet cable isn't being used: Due to the Auto-MDIX feature of the EtherPath
LAN ports, either straight-through or crossover ethernet cables may be used
interchangeably.
●
The ethernet cable has been plugged in all the way
S:
To
verify the
PC configuration
, check that:
●
The IP address and Subnet Mask for the EtherPath's default subnet is configured correctly
on the PC:
The EtherPath is using the default IP address 192.168.1.1
.
●
The PC has the proper IP address and does not have a previously-defined IP address
which conflicts with the one needed here.
●
The ARP Cache does not contain an entry from an earlier connection: Using a Command
Window (as Administrator), type the command
arp -a
to view the entire table of entries.
●
The Properties of the LAN connection do not still have “
Obtain an IP address
automatically
” selected: Leaving this on is a common issue.
●
The PC does not have a different network simultaneously connected: This often happens
when the Wireless LAN adapter is left enabled, so it should be turned off during the
Quick Start procedure.
S:
To
verify the
browser configuration
check that:
●
The browser is not trying to use a Proxy to connect: For the Quick Start procedure, the
Network settings for the browser should be “No Proxy”.
●
HTTP is being used to address the EtherPath, not HTTPS.
P:
The two EtherPaths are connected using an
ethernet cable between the LAN ports but no end-
to-end serial connection is established.
S:
To
verify the
physical connection
, check that:
●
The serial cables from each PC to its respective EtherPath device are fully plugged-in.
●
The serial connections both contain a null modem (“crossover”): If a “straight through”
cable is used on either end, the serial link will not work.
