IMG 1010 - Hardware Installation

Mounting
The IMG 1010 can be mounted in a 19-inch rack. The mounting brackets can be mounted at
either the front or the middle of the chassis.
If mounting multiple IMG 1010's in a rack, ensure
that a hazardous condition does not exist due to
uneven mechanical loading.
Avoid mounting inside a cabinet with closed doors
unless you can provide sufficient ventilation inside
the cabinet. Elevated operating ambient conditions
may occur in an enclosed equipment rack. The
operating ambient temperature may be greater
than the room temperature.
Do not block the front of the chassis; doing so can
cause the unit to overheat.

Electromagnetic Interference
Electromagnetic Interference (EMI) is a type of radiation that can hinder your system. Keep
the following in mind when selecting cables:
Shielded cable prevents outside electrical interference and drains off any induced current.
Twisted wire reduces induction, and thus interference, from one wire to the other. Varying
the length of twists reduces the potential for signal interference between pairs.
Twisted pair wiring is available in various thicknesses. Thicker cable covers longer
distances and provides better sound quality but it is more expensive.
Channel Service Units
A Channel Service Unit (CSU) connects a digital phone line (T1, E1) from the phone company
to a digital communications device. CSUs are required between all telecommunication ports
and the network to provide necessary linking capabilities such as:
Line conditioning for long haul transmissions
Remote loopback
Equalization
Regeneration and monitoring of digital signals
Digital circuit testing
Protection from outside lines
Electrostatic Discharge Protection
Electrostatic Discharge Protection (EDP) must always be used. Electrostatic Discharge (ESD)
protective straps, shoes, or mats must be used when working with electronic components.
Electrostatic discharge from your body can damage
integrated circuits during installation.
