Chapter 2. Installing the console unit in the rack
The console unit occupies 1U of mounting space in a rack. To install the console unit in the rack, complete
the steps in the following sections. Removing the rack doors and side panels, and removing the rack devices
that are above and below where you want to install the console unit, might make installation easier.
See the documentation that comes with your rack for additional information.
Guidelines for rack mounting the console unit:
• Elevated operating ambient - If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment might 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 overcurrent 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. Particular
attention should be given to supply connections other than direct connections to the branch circuit (for
example, use of power strips).
