Rack Mount Safety Instructions (UL)
When installing the chassis in a rack, be sure to implement the following
Safety instructions recommended by Underwriters Laboratories:
• Elevated Operating Ambient - 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 maximum
ambient temperature (Tma) specified by the manufacturer.
• Reduced Air Flow - Installation of the equipment in a rack should be such
that the amount of air flow required for safe operation on the equipment is not
compromised.
• Mechanical Loading - Mounting of the equipment in the rack should be such
that a hazardous condition is not achieved due to uneven mechanical loading.
• Circuit Overloading - Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits
might have on overcurrent protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should be used when
addressing this concern.
• 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.)
3.2.3.2 Installing the MP-124 in a 19-inch Rack
The MP-124 is installed into a standard 19-inch rack by the addition of two short (equal-

To install the MP-124 in a 19-inch rack, take these 7 steps:
1. Remove the two screws on one side of the device nearest the front panel.
2. Insert the peg on one of the brackets into the third air vent down on the column of air
vents nearest the front panel.
3. Swivel the bracket until the holes in the bracket line up with the two empty screw holes
on the device.
4. Use the supplied screws to attach the bracket to the side of the device.
5. Repeat steps 1 to 4 to attach the second bracket to the other side of the device.
6. Position the device in the rack and line up the bracket holes with the rack frame holes.
7. Use four standard rack screws (not supplied) to attach the device to the rack.
