Mounting the SME 100
This section provides information on installing the SME 100 in a rack cabinet. Rack
installation requires the use of the included brackets.
There are a variety of rack cabinets on the market, which may mean the assembly
procedure will differ slightly. If necessary, refer to the instructions that came with the rack
cabinet to complete the rack installation.
UL Guidelines for Rack Mounting
The following Underwriters Laboratories (UL) guidelines are relevant to the safe installation of
this product in a rack:
1. Elevated operating ambient temperature — If the unit is installed in a closed or
multi-unit rack assembly, the operating ambient temperature of the rack environment
may be greater than room ambient temperature. Therefore, install the equipment in an
environment compatible with the maximum ambient temperature
(TMA: +122 °F, +50 °C) specified by Extron.
2. Reduced air flow — Install the equipment in the rack so that the equipment gets
adequate air flow for safe operation.
3. Mechanical loading — Mount the equipment in the rack so that uneven mechanical
loading does not create a hazardous condition.
4. Circuit overloading — Connect the equipment to the supply circuit and consider the
effect that circuit overloading might have on overcurrent protection and supply wiring.
Consider the equipment nameplate ratings when addressing this concern.
5. Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted
equipment. Pay particular attention to supply connections other than direct connections
to the branch circuit (such as the use of power strips).
Rack Mounting
The SME 100 comes with two rack mounting brackets. To mount the SME 100, secure the
rack mount brackets to the front of the rack (see figure 121).
