For proper airflow and cooling of the shelf, the shape of the vertical posts of the rack should be such that the
airflow vents are not covered. There must be sufficient space between the shelf side walls, and the vertical
walls of the rack post that are parallel to the shelf side walls, as shown in the figure below.

Cisco NCS 2006 Shelf
The NCS 2006 is designed to comply with Telcordia GR-1089-CORE, Issue 5.
The NCS 2006 provides only Type 2 and Type 4 interfaces. A single NCS 2006 shelf supports both ANSI
and ETSI standards.
The NCS 2006 is FIPS 140-2 and CC compliant.
The NCS 2006 shelf has 8 horizontal card slots numbered 1 to 8. While Slot 2 to Slot 7 house MSTP cards
that provide 10 to 100 Gbps interconnections, Slot 1 and Slot 8 accommodate the TNC, TNCE, TSC, or TSCE
cards (timing and control cards). The NCS 2006 system can be powered by redundant AC or DC power
modules. A single power module (AC or DC) can be used to power up the entire NCS 2006 system. The NCS
2006 system contains backup flash memory that supports the database (DB) and image backup in the single
mode operation.
