6.10 Rack Mounting
All IP Office control units and expansion modules except the Small Office Edition can be rack mounted. To do this
requires a separate rack mounting kit for each unit and module.
Installation Requirements
In addition to the existing environmental requirements for an IP Office system, the following additional factors must be
considered when rack mounting a unit:
•
Rack Positioning
Ensure compliance with the rack manufacturers safety instructions. For example check that the rack legs have
been lowered and fixing brackets have been used to stop toppling.
•
Elevated Operating Ambient
If installed in a closed or multi-unit rack assembly, the operating 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. Proper ventilation must be maintained. The side ventilation slots on the IP500
control unit should not be covered or blocked.
•
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 (e.g. use of power strips).
Parts and Equipment Required
•
Rack Mounting Kit (SAP 700210800)
This kit contains all the components required for the rack mounting of a single control unit or
expansion module. This includes screws for fixing of the brackets to the module and bolts for
securing the module in the rack.
•
Barrier Box Rack Mounting Kit (SAP 700293905)
Barrier boxes must be used for out-of-building analog phone extensions . This bracket allows up to 8
IP Office barrier boxes to be rack mounted and simplifies the number of connections to the
protective ground point in the rack.
•
Must be used when more than 3 Barrier Boxes are in use.
•
A maximum of 16 Barrier Boxes are supported on any module.
