Loading By The Chassis - Sun Microsystems Datacenter Switch 3456 Installation Manual

The Sun Datacenter Switch 3456 casters all swivel freely. The chassis responds to
■
the greater of applied forces. This means that a person pushing on one corner to
move the chassis will also cause the chassis to rotate. So at least two people
should push equally on adjacent corners to move the Sun Datacenter Switch 3456.
When rolling the Sun Datacenter Switch 3456 off of the shipping pallet and down
■
the shipping ramp, the chassis will catch at the junction of the pallet and ramp,
and will have a tendency to rotate. Expect and prepare for this behavior.
To accelerate the Sun Datacenter Switch 3456 to a walking speed requires effort,
■
time, and distance. To stop the Sun Datacenter Switch 3456 from moving requires
the same or more. To accelerate, transport, or stop a Sun Datacenter Switch 3456
requires slow methodical movement, a clear and safe path, and sufficient
personnel aware of their actions.
Caution – The Sun Datacenter Switch 3456 chassis cannot be safely moved by one
person alone. Never allow any person near the direct path of the Sun Datacenter
Switch 3456. Personnel moving the Sun Datacenter Switch 3456 should consciously
keep their feet away from the bottom edge of the Sun Datacenter Switch 3456,
because this is a pinch point and can cause injury. Personnel moving the Sun
Datacenter Switch 3456 should stand to either side of the chassis or behind its
direction of motion.

Loading by the Chassis

The Sun Datacenter Switch 3456 can only be located on surfaces that can
accommodate its weight. The four casters on the Sun Datacenter Switch 3456 chassis
have a total contact area of 8 square inches or a loading of 225 psi. This load should
not be of concern, if the surfaces or foundations are concrete or reinforced.
Unreinforced wood surfaces cannot support the weight of the Sun Datacenter Switch
3456, and even if only temporary during movement, might flex enough to cause
bottoming out.
Carpeted surfaces might not be able to survive the stress of the Sun Datacenter
Switch 3456 casters, especially when turning. Additionally, movement over carpet is
difficult.
