Add Control Complex
Use the following procedure to add a redundant control complex. This procedure assumes that the original control
complex (i.e. the SCM in slot 19 and the RCM in slot 17) are in service.
 To add a Control Complex (Change from Simplex to Duplex)
Note: Ensure that your system is committed before starting this procedure. Use the reload commit command if
necessary.
Caution: Do not insert the SCM 20 or RCM 18 modules until instructed to do so later in this procedure.
1. Configure a second SCM slot:
configure slot 20 type SCM
2. Configure a second RCM slot:
configure slot 18 type RCM
3. Put slots 20 and 18 in the administrative up state:
configure slot 20 no shutdown
configure slot 18 no shutdown
4. (Optional) If using out-of-band management, configure the IP address of the second SCM in slot 20:
configure interface ethernet 20/0 ip address <ip address> <subnet mask>
In the next step you assign the out-of-band ethernet active IP address (19/0 and 20/0). It remains the active IP even
after a failover.
Note: If you are currently using telnet to access the SCM 19, you will be disconnected and have to log back in to the
system.
5. (Optional) If SCM 19 does not have an active IP address, assign one using the following command:
configure interface ethernet 19/0 active ip <address> [<subnet mask>]
Where: valid slot number = 19 or 20, either can be used to set the active IP.
In this case use slot 19 because the SCM is not yet present in slot 20.
If the IP mask is not provided, it defaults to the mask of the SCM interface ip address.
