CAUTION: 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.)
Installing the V7111 24-PORT in a 19-inch Rack
The V7111 24-PORT is installed into a standard 19-inch rack by the addition of two short
(equal-length) supplied brackets. The V7111 24-PORT with brackets for rack installation is
shown in
To install the V7111 24-PORT in a 19-inch rack, follow 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
3 Swivel the bracket until the holes in the bracket line up with the two empty screw holes
