fourth panel can be laid in front of the chassis in the direction of travel. Once the

chassis has rolled off the rear-most panel, lift that panel and move it to the front.

Repeat this process down the path over carpeting.

Grades

The Sun Datacenter Switch 3456 chassis weighs 1433 pounds (650 kg) as shipped.

Any grade along the path requires additional effort to move the chassis, or prevent

the chassis from moving. Do not attempt to move the chassis up or down a grade

greater than 3%.

Additionally, the Sun Datacenter Switch 3456 chassis is equipped with antitilt bars

that are mounted at the centerline. The presence of the bars limits the clearance

movement to 0.5 inch (12 mm). When a chassis peaks a grade of 3% or greater, the

antitilt bars bottom out.

If the path to the final location requires use of an elevator, ensure that the elevator

can safely accommodate the weight of the Sun Datacenter Switch 3456 chassis and

the personnel moving it.

The elevator doors must be wide enough to allow the Sun Datacenter Switch 3456 to

pass, ideally with personnel alongside. The doors might need to be held open, either

physically, or by pressing the door open button within the elevator.

Verify that the threshold at the elevator doors permits the chassis to enter and exit

the elevator. The gap between the floor and elevator should not be too large, nor

should there be any height difference. Check this gap at both the entering and

exiting floors. If there are any minor discrepancies, a metal sheet or masonite panel

can be used to compensate.

Doors must open wide enough to accommodate the Sun Datacenter Switch 3456

chassis and personnel alongside. Additional personnel can hold doors open, or the

doors can be securely propped open using wedges or catches. Do not hold doors

open with chairs or other easily available objects. Such objects do not guarantee a

secure door and can diminish the space for moving the chassis.
