Table 5-1. Problems and Error Messages

lit, then the physical network connection is bad. Confirm that you are using a
good network connection.
Problem/Message
Reason
Solution
When you issue the ARP –S
command in Windows, “The ARP
entry addition failed: 5" message
displays.
Your currently logged-in user does
not have the correct rights to use this
command on this PC.
Have someone from your IT
department log you in with sufficient
rights.
When you attempted to assign an IP
address to the SDS via the ARP
method, the “Press Enter to go into
Setup Mode” error (described below)
displayed. Now when you Telnet to
the SDS, the connection fails.
When you Telnet into port 1 on the
SDS, you are only assigning a
temporary IP address. When you
Telnet into port 9999 and do not
press Enter quickly, the SDS will
reboot, causing it to lose the IP
address.
Telnet back into 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
message “Press Enter to go into
Setup Mode
”
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
message “Press Enter to go into
Setup Mode.”
When you Telnet to port 1 to assign
an IP address to the SDS, 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.
