Converting the rails for round-hole racks
By default, the rack rails are configured for square-hole racks with load-bearing pins designed to
fit through the U-holes.
• If you are installing the disk enclosure in a square-hole rack, skip this section and continue with
"Installing the rails"onpage27.Donotremovethepinsfromtheendsoftherails.
• If you are in
stalling the disk enclosure in a round-hole rack, you must convert the rails as follows:
1. Locate the b

2. Locate the eight round-hole pins.
3. Use a No. 2 Phillips screwdriver to remove the standard pins from the front and back ends of a rail.
4. Install four round-hole pins into the rail (Figure 11).
5. Repeat st
eps 3 and 4 on the other rail.
