4 If you disabled Any IP (Section 7.6.7 on page 102), make sure your computer is
in the same subnet as the P-660H-T1v3s. (If you know that there are routers
between your computer and the P-660H-T1v3s, skip this step.)
• If there is a DHCP server on your network, make sure your computer is using
a dynamic IP address. See Appendix A on page 211. Your P-660H-T1v3s is a
DHCP server by default.
• If there is no DHCP server on your network, make sure your computer’s IP
address is in the same subnet as the P-660H-T1v3s. See Appendix A on page

of the advanced suggestions.
Advanced Suggestions
• Try to access the P-660H-T1v3s using another service, such as Telnet. If you can
access the P-660H-T1v3s, check the remote management settings and firewall
rules to find out why the P-660H-T1v3s does not respond to HTTP.
• If your computer is connected to the WAN port or is connected wirelessly, use a
computer that is connected to a ETHERNET port.
I can see the Login screen, but I cannot log in to the P-660H-T1v3s.
1 Make sure you have entered the password correctly. The default admin password
is 1234. The field is case-sensitive, so make sure [Caps Lock] is not on.
2 You cannot log in to the web configurator while someone is using Telnet to access
the P-660H-T1v3s. Log out of the P-660H-T1v3s in the other session, or ask the
person who is logged in to log out.
3 Turn the P-660H-T1v3s off and on.
