Installing The
Slides Into The
Rack
The assistance of a second person may be needed for the
following instrument rack assembly. Secure the slide mount
assembly in the designated location of the instrument rack using
the procedure below.
NOTE
To insure slide bracket kits are installed correctly to
the slides, it is necessary to install the rack mounting
ears (Items 4 and 5) to the mainframe at the desired
recess.
If the mounting rail of the instrument rack is tapped
for #10-32 screws, drill out two places for each
bracket using a
¼
inch diameter bit. Proceed with
the assembly.
Refer to
Figures 2-3, 2-4, 2-5
and
Table 2-1.
1. Take the 1261B mainframe and remove the button head cap
screw securing plastic trim pieces at top and bottom of front
side rails, both sides. Remove trim pieces and slide trim
plate from both side rails.
2. Reinsert plastic trim pieces top and bottom, position rack
mounting ears (Items 4 and 5) to give desired recess and
secure loosely with two flat head screws (Item 20) each side,
passing through the trim piece holes.
3. Insert rack mount ear shim plate (Item 6) in each side rail
groove and slide up behind rack mount ear. Align hole in
shim and ear and secure with flat head screw (Item 20) both
sides. Tighten top and bottom screws (Item 20).
NOTE
To comply with VXI
plug&play
receiver
interconnection specification for interlocking
receivers using interconnect adaptors, secure the
rack mount ear using the mounting holes adjacent to
the identifier hole (See Figure 2-5). This results in
meeting the requirement of 100.58 mm (3.960 in) from
the front surface of the rack mount ear to the
mounting surface of the VXI module front panel.
4. Depending on rack style (front or internal mounting rail),
choose appropriate rack brackets (long or short) Item 29, for
front and rear slide attachment. Attach brackets to slide
