Connecting Ethernet Cables to the ISE and
Network
Private Network Support
Ethernet connection between the system controllers requires high quality service in order to
maintain communications between them. Configuration information and critical messages
between the system controllers need to complete in order to stay in sync and maintain data
integrity. Various network disturbances can interfere with Ethernet connectivity, and disrupt
controller communications.
In order to prevent issues with quality of service, you must set up the system controllers and one
ICON system on a subnet or private/restricted network. The ICON system has two network
interfaces, which allows you to set up one on the private/restricted subnet and the other in the
public/corporate network to support the web-based management software. The ICON
configuration menu has options to set the IP address and netmask for a private/restricted
connection to the system controllers, and all ICON services such as the web-based management
are available on both interfaces.
Best Practice:
Using a private/restricted network protects time-critical controller-to-controller
communications from disruptions on the public/corporate network. Xiotech
requires segregating the public/corporate network from the private/restricted
network.
Note:
ICON does not route traffic between the two subnets.
Note:
If an iSNS server is used in the system, it must be accessible to the system
controllers’ management ports and to the servers. This may require connecting
the iSNS server to both the private and public networks.
