Additional System Security & HTTP Page
If your network security policies mandate against this type of data being accessible through HTTP pages, verify
that the HTTP page by setting Switch 2 Down and resetting the unit. For further security, restrict physical
access to the unit and the networks to which it connects.
If your network security policies allow you to use HTTP pages and you desire to have the HTTP page turned on
for troubleshooting, set Switch 2 Up and reset the unit.
Security Notes:
1. You can disable the Status Page by setting Option Switch 2 Down.
(Remember to reset the unit after changing switch settings.)
2. The Authorized PCs restricts the use of MCNRCD or MCN Server PCs.
It does not restrict Pings or the ability to access the HTTP page.
3. You can further restrict the HIB-IPs ability to talk to units outside its own subnet by setting its Gateway
address to "0.0.0.0". For this case, the status page will display “EMPTY” for the Gateway address as
shown above.
P INGING THE HIB-IP U NIT
The “Ping” function can be run from the PC as a diagnostic tool to determine if a particular IP address can be
“seen” by a PC and the network infrastructure is configured to pass ICMP Ping messages and responses. The
HIB-IP will respond to IGMP Ping messages from the IP network.
Note: Some networks are configured to block the ICMP Ping messages and/or responses between certain
network segments of subnets. The Ping function will not work if the ICMP Ping messages or responses are
blocked by the network.
