Removing and installing the outriggers (side stabilizers)
The outriggers are the stabilizers with wheels that are installed on the sides of the rack cabinet. After the
rack is in its final location and will not be moved more than 2 m (6 ft), you can remove the outriggers.
DANGER:
Always relocate the rack cabinet with the outriggers installed. Keep the outriggers and install them if you
have to move the rack to another location in the future.
Figure 3. Removing and installing the outriggers
To remove the outriggers, use the M5 hex wrench that comes in the hardware kit to remove the four bolts
that attach each outrigger to the rack cabinet. Keep the outriggers and bolts for future use if you have to
move the rack.
Note: Before you attach an expansion rack to a standard rack or another expansion rack, you must remove the
outriggers from the racks so that the racks fit together correctly.
Install the outriggers before you move the rack cabinet to another location. Use the M5 hex wrench that
comes in the hardware kit to install the four bolts that attach each outrigger to the rack cabinet.
Note: If lower side panels are attached to the upper side covers, you must remove the lower side panels

16
before you install the outriggers. For more information, see Installing and removing the lower side panels.
Installing the front stabilizer and the side stabilizer brackets
See the unpacking instructions that come with the rack cabinet for information about how to unpack and
locate the rack; then, lower the rack-leveling pads and install the front stabilizer for added stability.
