(RS) designations. References to the old designations may be shown when depicting actual text
(e.g., RS-232) displayed on front panel menus, Web Server pages, serial remote interfaces,
Telnet Command Line Interfaces (CLIs), or unit rear panels. All other references in the manual
refer to EIA designations.
Carefully review the following information.
Safety and Compliance
Electrical Safety and Compliance
The unit complies with the EN 60950 Safety of Information Technology Equipment (Including
Electrical Business Machines) safety standard.
Electrical Installation
Connect the unit to a power system that has separate ground, line and neutral
conductors. Do not connect the unit without a direct connection to ground.
Class I Pluggable Equipment Type A-Protective Earthing
The cable distribution system/telecommunication network of this product relies on protective
earthing and the integrity of the protective earthing must be ensured
In Finland:
"Laite on liitettävä suojakoskettimilla varustettuun pistorasiaan"
In Norway:
“Apparatet må tilkoples jordet stikkontakt”
In Sweden:
“Apparaten skall anslutas till jordat uttag”
Galvanic Isolator Use
Utrustning som är kopplad till skyddsjord via jordat vägguttag och/eller via annan utrustning och
samtidigt är kopplad till kabel-TV nät kan i visa fall medfőra risk főr brand. Főr att undvika detta
skall vid anslutning av utrustningen till kabel-TV nät galvanisk isolator finnas mellan utrustningen
och kabel-TV nätet.

The SLM-5650C CyberLynxTM Satellite Modem is offered in two unique packages:
•The SLM-5650C indoor unit (referred to as the SLM-5650C), shown in Figure 1-1, uses
conductive cooling and provides for mounting in any orientation via either the thermal
mounting rails or directly to the top or bottom surface.
•The SLM-5650C outdoor unit (referred to as the SLM-5650C-ODU), shown in Figure 1-2,
incorporates either conductive or convection cooling.
