Install additional mounting rails
If you are installing controller-drive trays, or drive trays that were shipped separately (not already
installed in the cabinet), you might need to install additional mounting rails in the cabinet.
Steps
1.
Determine the location for the mounting rails.
• Above an existing tray – Position the mounting rails immediately above the top tray in the
cabinet.
• Beneath an existing tray – Position the mounting rails with enough clearance to hold the tray
being installed:
◦ 8.9 cm (3.5 in.) for 2U controller-drive trays or drive trays
◦ 17.8 cm (7 in.) for 4U controller-drive trays or drive trays
2.
Use the measurement markers on the right-front and left-front vertical supports to attach the
mounting rails to the same position on each side of the cabinet.
