Step 1 – MFD IP Address
This is the IP address that is used for access to these administrator
web pages. It is also used for host computer connection to the
MFD/printer. This IP address was already set in the initial setup
process using the card reader keypad.
If you wish to change this address, it can be done using this screen or
from the card reader keypad.
Note: When you press the Update button, the CACStar will switch to
the new IP address which will cause your browser to be
disconnected from the CACStar. To reconnect, redirect your browser
to the new IP address you just entered.
Step 2 – NTP Server:
Set this to the Network Time Protocol Server IP address or Server
Name. This will allow the CACStar to validate certificates by date.
If DHCP is in use, you may check the "NTP From DHCP" box to force
retrieval of the NTP Server address from the DHCP server in which
case the address field is not used and may be left blank.
Step 3 – Configure Gateway and DNS Server
Note: A DNS Server is required for OCSP support. It is not necessary
to configure a DNS server if you are not using OCSP.
Set this to the DNS IP address to be used by the CACStar for Domain
Name resolution.
Example: 10.5.1.2
If DHCP is in use, you may check the "DNS From DHCP" box to force
retrieval of DNS addresses from the DHCP server - in which case the
DNS address fields are not used and may be left blank.
