Support rails and enclosures
Storwize V5000 Gen2 systems use the same rails and enclosures for both control and expansion
enclosures. All Storwize V5000 Gen2 models use the same expansion enclosure.
• The ledge on the inside of each rail supports the entire length of an enclosure.
• The enclosure support rails capture the left and right rear edges of an inserted enclosure. This prevents
the installed enclosure bouncing when the rack is subjected to quake or vibration.
• The enclosure support rails adjust to fit racks from 595 mm to 755 mm deep, measured between the
front and rear rack rails.
