RACKMOUNTING INSTALLATION
DIMENSIONS
SLIDE-OUT TRACKS
W A R N I N G
If the left and right slide-out tracks are reversed, the
safety latch can be defeated, allowing the instrument
to be pulled out of the rack. When mounting the slide-
out tracks, differentiate the left assembly from the
right and mount only as directed in these instructions.
The hardware provided for mounting the slide-out tracks
is shown in Fig. 6-1. Since the hardware is intended to make
the tracks compatible with a variety of cabinet racks and
installation methods, only part of the hardware will be need
ed for this installation.
Height. At least nine inches of vertical space is required
to mount this instrument in a cabinet rack.
Width. Minimum width of the opening between the left
and right front rails of the rack must be 17.9 inches. This
allows room on each side of the instrument for the slide-out
tracks to operate freely, permitting the instrument to move
smoothly in and out of the rack.
Depth. The rackmount version requires 25 inches behind
the front rails for air circulation, power cord, and the neces
sary mounting hardware.
Figure 6-2 shows the rackmount version installed in a
cabinet-type rack. The slide-out tracks provided permit it to
be extended out of the rack for access to the back connec
tors. To operate in the extended position, be sure the power
cord and any interconnecting cables are long enough for this
purpose.
The slide-out tracks consist of two assemblies—one for
the left side of the instrument and one for the right side.
Figure 6-3 shows the complete slide-out track assemblies.
The stationary section of each assembly attaches to the
front and rear rails of the rack, and the chassis section is
attached to the instrument. The intermediate section slides
