Rack or Wall Mounting (SF 400/800)

The MultiModem SF 400/800 units can be rack (or wall) mounted with screws using the mounting
brackets.
Rack Mounting
Ensure proper installation of the unit in a closed or multi-unit enclosure by following the recommended
installation as defined by the enclosure manufacturer. Do not place the unit directly on top of other
equipment or place other equipment directly on top of the unit. If installing the unit in a closed or multi-
unit enclosure, ensure adequate airflow within the rack so that the maximum recommended ambient
temperature (50° C) is not exceeded. Ensure that the unit is properly connected to earth ground by
verifying that it is reliably grounded when mounted within a rack. If a power strip is used, ensure that the
power strip provides adequate grounding of the attached apparatus.
When mounting the equipment in the rack, make sure mechanical loading is even to avoid a hazardous
condition. The rack used should safely support the combined weight of all the equipment it supports.
Ensure that the mains supply circuit is capable of handling the load of the equipment. See the power label
on the equipment for load requirements.
This equipment should only be installed by properly qualified service personnel. Only connect like circuits
- connect SELV (Secondary Extra Low Voltage) circuits to SELV circuits and TN (Telecommunications
Network) circuits to TN circuits.
Note: The ambient temperature of the rack interior must not exceed 50° Celsius.

equipment racks vary, screws for rack-rail mounting are not provided. Follow the instructions of the rack
manufacturer and use screws that fit.
1. Position the right rack-mounting bracket on the MultiModem iSMS using the two vertical mounting
screw holes.
2. Secure the bracket to the MultiModem iSMS using the two screws provided.
