Differences between OSN 8800 platform subracks and universal platform subracks
An OSN 8800 universal platform subrack provides 20 slots. Slots IU1 and IU2 house SCC boards. When only one SCC board is configured, IU2 can house a service board. When an OSN 8800 universal platform subrack functions as a slave subrack, no SCC board can be configured. In this scenario, both IU1 and IU2 can house service boards.
