Rack Precautions

Chapter 2 Setting Up and Configuring the Multi Services Platform

Mounting the Multi Services Platform in a Rack

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

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, if applicable.

A Multi Services Platform with hard drives and rails installed is heavy. Make sure that you have assistance when moving it and placing it into a rack.

Rack Mounting Considerations

Make sure to install the Multi Services Platform in an environment that is within its rated operating temperature and humidity range (see Cisco Physical Security Multi Services Platform User Guide). If the Multi Services Platform 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 Multi Services Platform.

Leave at least 1 rack unit (RU) of space between devices in the same rack.

Mount the Multi Services Platform in a manner that ensures that a hazardous condition does not arise due to uneven mechanical loading.
