Supermicro cse-745btq-r1k28b-sq — guidelines for Safe Rack Installation and Equipment Mounting [69/96]

Chapter 6: Rack Installation

To prevent bodily injury when mounting or servicing this unit in a rack, you

must take special precautions to ensure that the system remains stable.

The following guidelines are provided to ensure your safety:

•This unit should be mounted at the bottom of the rack if it is the only unit in

the rack.

•When mounting this unit in a partially lled rack, load the rack from the bottom

to the top with the heaviest component at the bottom of the rack.

•If the rack is provided with stabilizing devices, install the stabilizers before

mounting or servicing the unit in the rack.

Rack Mounting Considerations

Ambient Operating Temperature

If installed in a closed or multi-unit rack assembly, the ambient operating temperature

of the rack environment may be greater than the ambient room temperature. There-

fore, consideration should be given to installing the equipment in an environment

compatible with the manufacturer’s maximum rated ambient temperature (TMRA).

Reduced Airow

Equipment should be mounted into a rack so that the amount of airow required

for safe operation is not compromised.

Mechanical Loading

Equipment should be mounted into a rack so that a hazardous condition does not

arise due to uneven mechanical loading.

Circuit Overloading

Consideration should be given to the connection of the equipment to the power

supply circuitry and the effect that any possible overloading of circuits might have

on overcurrent protection and power supply wiring. Appropriate consideration of

equipment nameplate ratings should be used when addressing this concern.

Reliable Ground

A reliable ground must be maintained at all times. To ensure this, the rack itself

should be grounded. Particular attention should be given to power supply connec-

tions other than the direct connections to the branch circuit (i.e. the use of power

strips, etc.).
