Pre-Installation Considerations

The IMG 2020 has the following location requirements:
IMG 2020 | Location requirements |
-48 V DC | Restricted area, such as a dedicated equipment room or limited access office with access only by trained personnel. |
120/240 V AC | Does not have to be in a restricted area. Can be located in a clean and well-ventilated office space. |
Locating the Base MAC Address
The base MAC address is printed on the identification label located on the underside rear of the IMG 2020. The base MAC address is assigned to the CTRL ports. The other MAC addresses are under software control.
Use this base MAC address when configuring the IP address. Because of its location, we recommend that you obtain the base MAC address before you install the system. The identification label is similar to this example:

Space Requirements
Allow approximately 76 cm (2.5 ft) of space in front of the IMG 2020 for removing and maneuvering it with ease. Leave enough room so that air flow to the fans at the front and the vent holes at the side and rear are not obstructed. Do not put the IMG 2020 inside a cabinet with closed doors unless you can provide sufficient ventilation inside the cabinet.
The operating ambient temperature may exceed room temperature in an enclosed equipment rack.
Caution: When installing the IMG 2020, do not block the fans at the front as this will cause the unit to overheat.
Electromagnetic Interference
Electromagnetic interference (EMI) can affect the performance of your system. When selecting cables, keep the following information in mind:
Shielded cables prevent 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 telephone company to a digital communications device. CSUs are required between all telecommunications 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
Always use electrostatic discharge protection when working with electronic components. This protection includes electrostatic discharge (ESD) protective straps, shoes, or mats.
Caution: Electrostatic discharge from your body can damage integrated circuits during installation.
