Cisco SCE8000 GBE Installation And Configuration Manual page 96

Cascaded Systems
To maintain link continuity at all times, including during the reload sequence and power failure events,
optical bypass modules must be installed.
Connect both Cisco SCE8000 GBE platforms to the management station. (See
Step 2
Management Interface, page
Connect the cascade ports. See
Step 3
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 one set of cascade ports to a single switch (3/2/0 <-> 3/2/0). 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 the other set of cascade ports (3/3/0 <-> 3/3/0) 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 should reside on the VLAN.
Set topology configurations for each Cisco SCE8000 GBE platform via the connection-mode options.

platform was selected.
Use the show interface linecard 0 connection-mode command.
If you want to start with bypass, change the link mode to your required mode in both Cisco SCE8000
Step 6
GBE platforms on all links. The bypass mode will be applied only to the active Cisco SCE8000 GBE
platform. (See
Make sure that the link mode is as you required. (See
Step 7
Use the show interface linecard 0 link mode command.
Connect the traffic ports of Cisco SCE8000 GBE platform #0. This will cause a momentary down time
Step 8
until the network elements from both sides of the Cisco SCE8000 GBE platform auto-negotiate with it
and start working (when working inline). See
Step 9 Connect the traffic ports of Cisco SCE8000 GBE platform #1. This will cause a momentary down time
until the network elements from both sides of the Cisco SCE8000 GBE platform auto-negotiate with it
and start working (when working inline). See
When full control is needed, change the link mode on both Cisco SCE8000 GBE platforms on all links
Step 10
to 'forwarding'. It is recommended to first configure the active Cisco SCE8000 GBE platform and then
the standby. (See
You can now start working with the Subscriber Manager.
