mind that even when multiple hosts share the same server, access to
the server’s administrative functions is still protected. If you need to
change some configuration settings, you will have to ask your admin-
istrator for help. If you are the administrator but forget the password,
you can erase the current password yourself by pressing the RESET
key on EDG-4508/4516 ’s back panel for three seconds.
2. Error Installation Type - You cannot change the server IP address if
you are installing EDG-4508/4516 under Single-Host Mode. Setting
the installation procedure up in this way makes the Single-Host Mode
configuration procedure very similar to installing a traditional multi-
port serial board. Under Single-Host Mode, users are only allowed to
modify the server’s name and password. This is because Single-Host
users are not sharing their EDG-4508/4516 with other hosts. If you do
need to modify other properties, run the setup program and change to
another mode of operation (see Chapter 8 for details).
➢
You would like to allow one more host to access your EDG-4508/4516
, but are unable to reach the page for Access Control.
1. Check the EDG-4508/4516 Manager mode. If it is Single-Host Mode,
reinstall it as either Multi-Host Mode or Custom Mode.
2. Double check your credentials to make sure that you are the adminis-
trator.
➢
After installing EDG-4508/4516 , the EDG-4508/4516 Manager program
indicates “‘Un-authorized” status for some of the ports.
This means that EDG-4508/4516 ’s Access Control List does not con-
tain your computer’s correct IP address. This can happen in one of
two ways:
1. Your NT/95/98 machine is just one of the hosts sharing the ports on
the selected server, and you do not provide the server password while
installing EDG-4508/4516 .
