After a successful Administrator Logon authentication, the Filter list will upload to the Secure KVM Switch. The
Secure KVM Switch will allow or block USB devices connected to the USB CAC port based on the updated Blacklist
and Whitelist.
The Administrator Logon session terminates automatically after the filtering list is updated. To make the updated
filtering list take effect, remove the IOGEAR Secure KVM Switch from the installation and power cycle the Secure
KVM Switch.

The Blacklist and Whitelist defined by the Administrator Logon Functions always supersedes the
filtering list created by the Port Authentication Utility. The administrator should make sure that
there is no conflict when editing device entries.

The updated filtering list will overwrite the one previously uploaded to the Secure KVM Switch.

A 2‐port based Filtering list can only be uploaded to 2‐Port Secure KVM models. (4‐Port list to
4‐Port models; 8‐Port list to 8‐Port models). An error message shows up when uploading the
wrong filtering list.

The only way to clear the Blacklist and Whitelist updated by the Port Authentication Utility is for
the administrator to perform "Reset KVM to Default" (This Reset KVM to Default also clears the
Blacklist and Whitelist created by the Secure KVM administrator functions.
Please refer to the IOGEAR Administrator's Guide for more details.)
