Cisco SCE8000 GBE Installation and Configuration Guide

Chapter 6 Cabling the GBE Line Ports and Completing the Installation
Cascaded Systems
To maintain link continuity at all times, including during the reload sequence and power failure events,
optical bypass modules must be installed.
Step 2 Connect both Cisco SCE8000 GBE platforms to the management station. (See Connecting the
Management Interface, page 5-4.)
Step 3 Connect the cascade ports. See Dual Cisco SCE8000 GBEs Topology, page 6-3
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.
Step 4 Set topology configurations for each Cisco SCE8000 GBE platform via the connection-mode options.
(See How to Configure the Connection Mode, page 6-15.)
Step 5 Make sure that the Cisco SCE8000 GBE platforms have synchronized and active Cisco SCE8000 GBE
platform was selected.
Use the show interface linecard 0 connection-mode command.
Step 6 If you want to start with bypass, change the link mode to your required mode in both Cisco SCE8000
GBE platforms on all links. The bypass mode will be applied only to the active Cisco SCE8000 GBE
platform. (See How to Set the Link Mode, page 6-16.)
Step 7 Make sure that the link mode is as you required. (See Monitoring a Cascaded System, page 6-17.)
Use the show interface linecard 0 link mode command.
Step 8 Connect the traffic ports of Cisco SCE8000 GBE platform #0. 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 Dual Cisco SCE8000 GBEs Topology, page 6-3
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 Dual Cisco SCE8000 GBEs Topology, page 6-3
Step 10 When full control is needed, change the link mode on both Cisco SCE8000 GBE platforms on all links
to ‘forwarding’. It is recommended to first configure the active Cisco SCE8000 GBE platform and then
the standby. (See How to Set the Link Mode, page 6-16.)
Step 11 You can now start working with the Subscriber Manager.
