Chapter 2
Installation
This chapter instructs you on how to install the NSG 9000 device. For best results, perform
the required actions according to following order:
“Unpacking the NSG 9000 Platform” on page 23
“Installing the NSG 9000 Platform” on page 24
“Inserting the Modules” on page 29
“Installing a DTI Card (Optional)” on page 32
“Connecting Power” on page 42
2.1
Unpacking the NSG 9000 Platform
The NSG 9000 platform comes in a specially designed shipping container that ensures its
safety during shipping and handling. To avoid damaging the NSG 9000 platform, unpack it
carefully. The container includes the following:
Chassis - front panel is attached but no modules are mounted
Processing module - the module is static sensitive. Unpack, following the ESD guidelines
on
2.3 Inserting the Modules
on page 22.
The QAM-RF modules and power supply units are shipped separately.
2.2
Installing the NSG 9000 Platform
NOTE:
The NSG 9000 platforms are used in restricted access locations.
NOTE:
To prevent body injury when mounting or servicing this platform in a rack, you must take special
precautions to ensure that the system remains stable. Read the following guidelines to assure your safety.
2.2.1
Rack Specifications
Install the 2-RU chassis in the following rack:
a standard EIA 19-inch computer rack with at least 30” (76cm) depth.
To allow free air flow, the rack must be completely open at its front side.
The rack should be mounted with side walls and a back door.
The back door should have ventilation slots at its bottom part.
The top of the rack should be closed and mounted with cooling fan(s). For fan
requirements, see following section.
2.2.2
Rack Ventilation
Each NSG 9000 unit requires ventilation of at least 2.2 M
3
\min (78 CFM). Calculate the
total required M
3
\min or CFM accordingly. In case devices of another type are mounted
on the rack, consider their cooling requirements as well.
For example, the combined air flow of fans mounted at the top of a rack mounted with ten
NSG 9000 devices is at least 22.7 M
3
/min (780 CFM).
