Installing Bar Nuts - HP NetServer LH 6000 Installation Manual

Chapter 8 Installing the HP NetServer in an HP Rack System/E or Rack System/U

Installing Bar Nuts

The "bar nut" is a two-hole metal bar used to secure the mounting flanges of the
slide to the rack columns.
All four mounting brackets on the slides attach behind the outside faces of the
columns, using bar nuts. Use the template (or if you no longer have it, count) and
mark the twentieth and twenty-second holes up from the baseline on each column.
These holes correspond to the bottom hole of the eighth EIA unit (and the middle
hole of the seventh EIA unit) above the baseline (see Figure 8-5).
Top is located at
8 EIA units from
baseline.
Slide mounting
holes at 20 and 22
from baseline on
all four columns.
Figure 8-5. Marking the Rack Columns for Bar Nuts
The bar nut is placed behind the outside face of the column, at the height
determined with the template, or by counting.
1. Insert two screws through the marked holes on the front columns.
2. Start (but do not tighten) two screws through the face of the bar nut. Install
the bar nuts on all four-rack columns.
