e
Select the default WANLink.
f
Select the IPRoutes page
g
Remove all the existing routes and add an entry to route back to the Primary Call Server, eg
IP Address = 194.168.0.0
IP Mask = 255.255.255.0
Metric = 1
h
Power down the Call Server, as described in the Powering down a Call Server section from
page 282.
i
Connect the Call Server to the Primary Call Server via your WAN link.
j
Power up the Call Server.
k
The WAN LEDs on both Call Servers will be solid if a connection has been made. You may
wish to ping the Primary Call Server to verify that you can communicate with the Primary, eg
ping 194.168.0.1
l
In Manager Assist select System Utilities
m
Under the Commands list select Ask Master
n
Within the Enter IP Address field enter the IP Address of the Primary Call Server, eg 192.168.0.1
o
Click on the Set Master button (ignore the system error message if displayed).
4
On the Primary Call Server:
a
In Manager select Unassigned Modules.
b
Select the new Call Server, eg Secondary Call Server
c
From the Module Status list box select Member.
d
Select Update or Apply when ready
e
Select Modules.
f
Select the Secondary Call Server, select the Call Server page and note that the Administration
Mode is set to Secondary.
5
On the Secondary Call Server
a
In Manager select the WAN Links.
b
Select the Secondary Call Server and select WANLink
c
Select the IPRoutes page and note that the default routes have reappeared.
d
Repeat step 3(g) above.
e
You may wish to ping the Primary Call Server to verify that you can communicate with the
Primary, eg ping 194.168.0.1
The Secondary Call Server will now be a part of the system controlled by the Primary Call Server. The
Primary Call Server will replicate the relevant configuration information to the Secondary Call Server. This
means that the configuration of the system can be administered from either Call Server.
Connecting a 5500 Network Service Gateway (NSG)
Initial considerations
x
A NSG will only operate as a secondary call server connected to a S8000 or 5100 Call Server
x
A NSG will stop operation if it loses contact with the Primary Call Server
x
A NSG will provide remote site cover, with full telephony functionality, if the S8000/5100 is
unavailable.
x
Ensure the Call Server and NSG are running the same version of software.
x
On power up, by default, a NSG will use 192.168.0.1 as its IP address and act as a DHCP Server. If this
is not required because, for example, 192.168.0.1 is already being used and another DHCP Server
exists on the network change this configuration via Setnet as described in the following instructions.
