Chapter 2 Setting Up and Maintaining the Multiservices Platform Series Device
Setting up a Multiservices Platform Series Device
Preparing for Rack Mounting
Before you install the Multiservices Platform Series device in a rack, review the following guidelines:
Choosing a Location
•
Leave enough clearance in front of the rack to enable you to open its front door completely
(approximately 25 inches).
•
Leave approximately 30 inches of clearance in back of the rack to allow for sufficient air flow and
ease of servicing.
•
The Multiservices Platform Series device is intended for installation in a restricted access location,
such as a dedicated equipment room or service closet.
Rack Precautions
•
Ensure that the leveling jacks on the bottom of the rack are extended to the floor with the full weight
of the rack resting on them.
•
In a single rack installation, attach stabilizers to the rack.
•
In a multiple rack installation, couple the racks to each other.
•
Make sure that the rack is stable before extending a component from the rack.
•
Extend only one component from a rack at a time. Extending two or more components may cause
the rack to become unstable.
General Precautions
•
Review the electrical and general safety precautions that come with the components that you add to
your chassis.
•
Determine the placement of each component in the rack before you install the rails.
•
Install the heaviest components on the bottom of the rack first, then work up.
•
Use a regulating uninterruptible power supply (UPS) to protect a device from power surges and
voltage spikes and to keep the device operating if a power failure occurs.
•
Close the front door of the rack and all panels and components on the servers when not servicing
them to maintain proper cooling.
Rack Mounting Considerations
•
Make sure to install the Multiservices Platform Series device in an environment that is within the
rated operating temperature and humidity range (see
Appendix A, “System Specifications”
). If the
Multiservices Platform Series device is installed in a closed or multi-unit rack assembly, be aware
that the ambient operating temperature of the rack environment may be greater than the ambient
temperature of the room.
•
Make sure that there is sufficient air flow for safe operation of the Multiservices Platform Series
device.
•
The Multiservices Platform Series device should be mounted in a rack so that a hazardous condition
does not arise due to uneven mechanical loading.
•
Consider the connection of equipment to the power supply circuitry and the effect that possible
overloading of circuits may have on overcurrent protection and power supply wiring. Consider
equipment nameplate ratings when addressing this issue.
•
Maintain a reliable ground. The rack itself should be grounded. Pay particular attention to power
supply connections other than direct connections to the branch circuit (for example, power strips).
