Installing the shelf onto the rails
P
rerequisites
If you are installing an empty shelf (all FRUs removed), you can install the chassis without using a lift. If the shelf is populated
with FRUs before installation, you must use a portable lift. Working with a portable lift on page 12 provides more information.
NOTE:
DO NOT ATTEMPT to install a populated shelf without a mechanical lift. Attempting to install a populated shelf
without a lift could damage the equipment and cause injury to personnel.
CAUTION:
Only install a shelf into a cabinet that is equipped with anti-tip features.
NOTE:
The following procedure shows an installation using the Alum-a-Lift portable lift. If another lift is being used, follow
the manufacturer's instructions for that lift as applicable.
NOTE:
A populated shelf requires two people and a lift to install. An unpopulated chassis requires three people to install.
About this task
CAUTION:
Secure the enclosure to the portable lift using the securing straps before moving the lift.
If you are installing a populated shelf, refer to S
liding the shelf chassis into the rails on page 33 while you perform the steps in
this task.
Steps
1. If a portable lift is not available or cannot access the rack, you must remove the components from the shelf before it is
installed on the rails:
a. Refer to the procedures for removing the Power Supplies, link control cards (LCCs), and Fan Modules and remove each
FRU.
b. Refer to the procedure for removing the disk drives and remove the disk drives. Label each disk drive with its exact
location so that it can be reinstalled once the shelf is installed in the cabinet.
2. Align the chassis rails with the inner rails that are attached to the cabinet. If you are using a lift, lock the casters into place.
NOTE:
If you are installing the shelf manually without a lift, you will need three people to install it: Two people to hold
the chassis in place at the correct height, and one person to align and manage the slides.
3. M
anually slide the inner rail over the chassis rail 2-3 inches to line them up.
