Problem/Message Reason Solution
When you attempt to assign an IP
address to the unit by the ARP
method, the "Press Enter to go into
Setup Mode" error "(described
below) message displays. Now
when you Telnet to the device
server, the connection fails. When you Telnet to port 1
on the device server, you
are only assigning a
temporary IP address.
When you Telnet into port
9999 and do not press
Enter quickly, the device
server reboots, causing it
to lose the IP address. Telnet back to Port 1. Wait for it to
fail, then Telnet to port 9999 again.
Make sure you press Enter quickly.
When you Telnet to port 9999, the
"Press Enter to go into Setup
Mode" message displays.
However, nothing happens when
you press Enter, or your
connection is closed. You did not press Enter
quickly enough. You only
have 5 seconds to press
Enter before the
connection is closed. Telnet to port 9999 again, but press
Enter as soon as you see the "Press
Enter to go into Setup Mode"
message.
When you Telnet to port 1 to
assign an IP address to the device
server, the Telnet window does not
respond for a long time. You may have entered the
Ethernet address
incorrectly with the ARP
command. Confirm that the Ethernet address
that you entered with the ARP
command is correct. The Ethernet
address may only include numbers
0-9 and letters A-F. In Windows and
usually in Unix, the segments of the
Ethernet address are separated by
dashes. In some forms of Unix, the
Ethernet address is segmented with
colons.
The IP address you are
trying to assign is not on
your logical subnet. Confirm that your PC has an IP
address and that it is in the same
logical subnet that you are trying to
assign to the device server.
The device server may not
be plugged into the
network properly. Make sure that the Link LED is lit. If
the Link LED is not lit, then the
device server is not properly plugged
into the network.
When you try to assign an IP with
DeviceInstaller, you get the
following :
"No response from device!
Verify the IP, Hardware
Address and Network Class.
Please try again."
The cause is most likely
one of the following:
The hardware address you
specified is incorrect.
The IP address you are
trying to assign is not a
valid IP for your logical
subnet.
You did not choose the
correct subnet mask.
Double-check the parameters that
you specified.
Note: You cannot assign an IP
address to a device server through a
router.
The device server is not
communicating with the serial
device to which it is attached. The most likely reason is
the wrong serial settings
were chosen. The serial settings for the serial
device and the device server must
match. The default serial settings for
the device server are RS-232, 9600
baud, 8 character bits, no parity, 1
stop bit, no flow control.
