Make sure that the SCE platforms have synchronized and active SCE platform was selected. Use the
Step 5
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
platforms on both links. The bypass mode will be applied only to the active SCE platform. (See
the Link Mode, page
Make sure that the link mode is as you required. (See
Step 7
the show interface linecard 0 link mode command.
Connect the traffic port of SCE platform #1. This will cause a momentary down time until the network

elements from both sides of the SCE platform auto-negotiate with it and start working (when working
inline).
Connect the traffic port of SCE platform #2, this will cause a momentary down time until the network
Step 9
elements from both sides of the SCE platform auto-negotiate with it and start working (when working

Power failure — manual or automatic recovery can be implemented.
Any failure resulting in a reboot — manual or automatic recovery can be implemented (this is
configurable).
3-consecutive reboots within half an hour — manual recovery only
Cascade ports link-failure — automatic recovery when link revives.
Traffic link failure — automatic recovery when link revives.
Failure in the communications with the SM — automatic by SM decisions after connection is
re-established.
Hardware malfunction — manual recovery, after replacing the malfunctioning SCE platform.
