Working with a portable lift
If you are installing the shelf with all field replaceable units (FRUs) removed, you can install the shelf without using a lift. If you
need to install the shelf with FRUs onboard, use a portable lift.
Service personnel generally use the portable lift manufactured by Alum-A-Lift. Instructions for this lift are included in the lift kit.
http://www.corkc4.isus.emc.com/wiki/index.php/Lift_Tool describes the Lift equipment and the ordering process.
NOTE: If you are using a portable lift other than the Alum-A-Lift, adapt these instructions as necessary while following all
required safety requirements.
Lift requirements
For installations in racks that are 28U (49 inches) or less above the floor, use the lower mast, which is rated for 400 pounds.
For installations in racks that are more than 28U (49 inches) above the floor, use the lower mast configuration and a support
table with the "Voyager" conversion kit, which is rated for 225 pounds.
Adjusting the arms for a frontal lift
About this task
If you plan to use the mechanical lift directly in front of the cabinet, adjust the width of the lift arm/tray to just under 17 inches
to ensure that the arms will stay under the chassis.
Steps
1. Adjust the two arms with rollers so that they are 17 inches apart measured from the outside edges.
2. Tighten the arms to secure them.
The following figure shows an example of adjusting the lift arm/tray to just under 17 inches.
