Chapter 2 Installing Trays 31
Attaching the Universal Rail Kit to a Standard
Sun or 19-Inch Cabinet With Threaded Cabinet
Rails
This procedure describes the steps to attach the universal rail kit to:
■ All standard Sun cabinets, including the Sun Rack 900/1000 cabinets
■ Sun StorageTek Expansion cabinets
■ All 19-inch wide, 4-post EIA-compatible racks and cabinets with the following
cabinet rail types:
■ M5 threaded
■ M6 threaded
■ 10-32 threaded
■ 12-24 threaded
■ circular un-threaded
1. To attach the universal rail kit to a cabinet with these cabinet rail types, position
the front flange of the left universal rail behind the left front cabinet rail
(
FIGURE 2-2).
Note – The U marks are not labeled on all racks, as they are on the Sun cabinets.
The rule of thumb to remember is that the division of RUs passes between the two
closest rail holes in each set of holes (see FIGURE 2-2).
