n
FS25 shelves weigh up to 44.61 lbs (20.23 kg).
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.
Procedure
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.
