Installing a Cascaded System
This section outlines the installation procedures for a redundant solution with two cascaded SCE 2000s. For more
complete information, refer to the Cisco SCE 2000 4/8xFE Installation and Configuration Guide. Refer to the Cisco SCE
CLI Command Reference for details of the CLI commands.
Warning
When working with two SCE 2000s with split-flow and redundancy, it is extremely important to follow this
installation procedure.
To install a cascaded system, complete the following steps:
Install both SCE 2000s, power them up, and perform the initial system configuration. (See
Step 1
Supply Units
(on page 11) and
Connect both SCE 2000s to the management station.(See
Step 2
Step 3
Connect the cascade ports. The cascade ports must be connected directly in Layer 1 (dark fibers), not through
switches. (See
Step 4
Set topology configurations for each SCE 2000 via the connection-mode options.
Parameters for Redundant
Step 5
Make sure that theSCE 2000s have synchronized and active SCE 2000 was selected.
Use the show interface linecard 0 connection-mode command.
Step 6
If you want to start with bypass/sniffing, change the link mode to your required mode in both SCE 2000s on
both links. The bypass mode will be applied only to the active SCE 2000. (See
Step 7
Make sure that the link mode is as you required.
Use the show interface linecard 0 link mode command.
Step 8
Connect the traffic port of SCE 2000 #1. This will cause a momentary down time until the network elements
from both sides of the SCE 2000 auto-negotiate with it and start working (when working inline). (See
Two
SCE
2000s Topology
Step 9
Connect the traffic port of SCE 2000 #2, this will cause a momentary down time until the network elements
from both sides of the SCE 2000 auto-negotiate with it and start working (when working inline). (See
Two
SCE
2000s Topology
When full control is needed, change the link mode on both SCE 2000s on both links to 'forwarding'. It is
Step 10
recommended to first configure the active SCE 2000 and then the standby. (See
You can now start working with the Subscriber Manager.
