Rack Mounting Brackets
The Midspan comes with 19-inch mounting brackets and screws. To
install the Midspan into a 19-inch rack, first remove the self-adhesive
rubber feet from the bottom surface. Install the brackets using two screws
per side. Rack-mounting screws are not provided.

General Hazards
a) Elevated Operating Ambient Temperature — if installed in a closed or
multi-unit rack assembly, the operating ambient temperature of the rack
environment may be greater than room ambient. Therefore, consideration
should be given to installing the equipment in an environment compatible
with the manufacturer's maximum rated ambient temperature (Tmra).

b) Reduced Air Flow — Installation of the equipment in a rack should be
such that the amount of air flow required for safe operation of the
equipment is not compromised.

d) Circuit Overloading — Consideration should be given to the connection
of the equipment to the supply circuit and the effect that overloading of
circuits might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be
used when addressing this concern.

e) Reliable Earthing — Reliable earthing of rack mounted equipment
should be maintained. Particular attention should be given to supply
connections other than direct connections to the branch circuit (e.g., use
of power strips)
