Backplane

The Cisco ONS 15530 backplane implements all board-to-board signal
interconnects and providespower distribution within the chassis. Connections are
present for two power supplies and the fan assembly. The backplane contains a
total of 12 slots; two half-height slots for the OADM modules, two full height
slots for the CPU switch modules, and eight full height slots for line cards and
transponder cards.

Cable Storage Drawer

The cable storage drawer is mounted directly below the fanassembly. It provides
storage for the excess cable length. Sliding radius limiters move to release the
excess fibercable slack when the drawer is pulled out, allowing the user to raise
the fiber routing tray and access the fan assembly.
