Cisco Cisco SCE 8000 Service Control Engine Installation Guide

The Link LED should be green.

Install both Cisco SCE 8000 platforms, power them up, and perform the initial system configuration.

To maintain link continuity at all times, including during the reload sequence and power failure events, it is 
recommended to install optical bypass modules.

Connect both Cisco SCE 8000 platforms to the management station.

Connect the cascade ports (see 

The cascade ports must be either be connected directly in Layer 1 (dark fibers), or using the following procedure to 
connect through a switch.

Connect port 3/2/0 from box A and port 3/3/0 from box B to a single switch. Configure them both on the same access 
VLAN, which will be used only by the interfaces connected to these ports. No other interfaces in the switch should 
reside on that VLAN.

Connect port 3/3/0 from box A and port 3/2/0 of box B to a switch on a different VLAN. Again, the access ports should 
be configured as access ports on this VLAN, which will be used only by the interfaces connected to these ports. No 
other interfaces in the switch reside on the VLAN.

Set topology configurations for each Cisco SCE8000 platform using the connection-mode CLI command.

Make sure that the Cisco SCE8000 platforms have synchronized and active Cisco SCE8000 platform was selected.

Use the show interface linecard 0 connection-mode command.

If you want to start in bypass mode, change the link mode to your required mode in both Cisco SCE8000 platforms on 
both links. The bypass mode will be applied only to the active Cisco SCE8000 platform.

Connect the traffic port of Cisco SCE 8000 platform #1. This will cause a momentary down time until the network 
elements from both sides of the Cisco SCE 8000 platform auto-negotiate with it and start working.

Connect the traffic port of Cisco SCE 8000 platform #2. This will cause a momentary down time until the network 
elements from both sides of the Cisco SCE 8000 platform auto-negotiate with it and start working.

When full control is needed, change the link mode on both Cisco SCE 8000 platforms on both links to ‘forwarding’. It 
is recommended to first configure the active Cisco SCE 8000 platform and then the standby.

You can now start working with the Subscriber Manager.
