Chapter 8 Installing the HP NetServer in the 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. Top is located at 8 EIA units from baseline.

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.
