CHAPTER 4
Installing the Air Flow Regulator
This chapter explains how to install the regulators to maintain the air flow for ANSI and ETSI configurations
in NCS 2002 shelf.
The air flow within the equipment must be maintained at a nominal temperature. This task can be accomplished
using one of these mechanisms:
•
Air deflector
•
Air plenum
The sections are:

Air Deflector
An air deflector is a sheet-metal part that is mounted on the NCS 2002 shelf to orient the air flow in a specific
direction.
The air deflectors can be mounted in different positions to control the air flow:
• Front to Front— Only ETSI rack
• Front to Back— For ANSI and ETSI racks
• Front to Top— Only ETSI rack
In an ANSI rack, the air deflectors are mounted only on the 23-inch rack configuration.
