Expansion enclosure support rails
The left and right expansion enclosure support rails (Figure 6 on page 8) are designed specifically for
installation of an expansion enclosure.
• The ledge on the inside of each rail supports the entire length of an expansion enclosure.
• The expansion enclosure support rails capture the left and right rear edges of an inserted expansion
enclosure. This prevents the installed control enclosure bouncing when the rack is subjected to quake
or vibration.
• The expansion enclosure support rails adjust to fit racks from 595 mm to 755 mm deep, measured
between the front and rear rack rails.
