Precautions for Rack Mounting
High operating temperature - If installed in a closed or multi-unit rack assembly, the operat-
ing ambient temperature of the rack environment may be greater than room ambient. Therefore,
consideration should be given to installing the equipment in an environment compatible with the
maximum ambient temperature (Tma) specified by the manufacturer.
Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air
flow required for safe operation of the equipment is not compromised.
Mechanical Loading -Mounting of the equipment in the rack should be such that a hazardous
condition is not achieved due to uneven mechanical loading.
Circuit Overloading –Consideration should be given to the connection of the equipment to the
supply circuit and the effect that overloading of the circuits might have on over-current protection
and supply wiring. Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.
Reliable Earthing – Reliable earthing of rack-mounted equipment should be maintained. Particu-
lar attention should be given to supply connections other than direct connections to the branch
circuit (such as use of power strips).
Maintenance with Input Power
We strongly recommend that you do not perform maintenance on MTBS BOX if it is receiving input
power.
To reduce your risk of personal injury by electric shock, you must:
• Be a certified electrician trained in live electrical installation
• Always work with another qualified person
• Know how to disconnect electricity to the MTBS BOX and data center in case of emergency
• Wear the right protective equipment
• Use double-insulated tools
• Strictly follow local and site regulations
