This rackmount kit supports the 3 Series MDO instruments.

The following tables list the parts for the RM3 rack mount kit; not all of the parts will be needed for your instrument setup.

The numbers in the illustration correspond with the item numbers in the preceding tables. Hardware in 016-2116-xx and 016-2142-xx kits are not pictured in the illustration.

When the instrument is installed according to the instructions in this document, the rackmounted instrument meets all warranted requirements listed in the instrument specification. Instruments mounted using methods other than those described in these instructions might not meet their warranted requirements.

For tables of the warranted characteristics, see Specifications in the specification and performance verification manual that applies to your instrument model.

CAUTION:The rack is more susceptible to tipping when the instrument is installed. To prevent the rack from tipping, ensure that the rack is stable before accessing rear panel of the instrument. Do not leave the instrument extended in the rack.

The ambient temperature inside the instrument rack will vary depending on the location of the instrument within the instrument rack. Tektronix recommends that you measure the ambient temperature in the desired rack location before you install the instrument to ensure the operating temperature does not exceed the rated ambient temperature limit. If necessary, refer to the Environmental Specifications in your product documentation for the operating temperature limits.

CAUTION:The instrument might be damaged due to overheating. When installing multiple instruments in an instrument rack, the ambient temperature may go up. You assume the responsibility to provide adequate cooling to meet the ambient temperature requirements listed in the specifications.

The rack in which the individual instrument is mounted must provide the following clearance requirements:

• At least 266 mm (10.5 in) of vertical space or 6 RU (rack units) of vertical space
• A minimum width of 488 mm (19.2 in) between the left- and right-front rails in the rack. If possible, consider allowing at least 50.8 mm (2.0 in) on the right side and rear of the instrument for adequate airflow.
• A minimum inside depth of at least 254 mm (10 in) depth (from rack mounting ear to back of instrument). Airflow enters from the back of the instrument and exits on the right of the instrument when viewed from the front.

CAUTION:Adhering to these requirements mounts the rack-adapted instrument with enough clearance for air circulation and accommodation of the power cord and mounting hardware. Failure to provide these clearances can result in overheating and can cause the instrument to operate improperly or fail.

   WARNING:To avoid personal injury and prevent the instrument from tipping or dropping, use two or more people to install this instrument into the rack cabinet. After completing the installation procedure, verify that the instrument and the rack cabinet will not tip forward while the instrument is in the extended position. Do not leave the instrument extended when finished accessing the instrument.
