(every the network
second)
There can be a break in the con-
nection between individual
slices, or one of the SmartSlice
sockets is not connected prop-
erly to its left neighboring con-
nector.
The TS LED on all correctly con-
nected slices are flashing, but
the TS LED on the not correctly
connected units are off.
The last unit is not or not prop-
erly connected. The SmartSlice

Backup operation in progress
onds)
Correction
Wait until the SmartSlice I/O Units
are added to the network
Check the connection between
slices at the point where the first unit
is located with its TS LED off.
Make sure that all slices are con-
nected correctly to each other.
Check the connection of the last unit
and make sure that it is correctly
connected to the SmartSlice system
Make sure that the base block of the
SmartSlice I/O System is connected
properly
Correct the configuration and turn
the power on again
Correct the unit configuration and
