5.17 Rack Mounting
The IP500 control unit and IP500 external expansion units can be
rack mounted if required into 19-inch rack systems. This requires
an IP500 Rack Mounting Kit (SAP 700429202) for each unit.
The kit includes:
•
A rack mounting bracket and screws for attachment of the
bracket to the unit
•
Nuts and bolts for rack attachment.
•
Brackets and cable ties for cable tidying.
As indicated in the diagram following, the rack mounting bracket
can be used in several positions on the unit. IP400 external
expansion units used in an IP500 system can also be rack mounted
but use a separate IP400 Rack Mounting Kit.
Environmental 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:
1. 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.
2. 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.
•
o
Operating Temperature: 0°C (32°F) to 40°C (104°F).
•
o Operating Humidity: 10% to 95% non-condensing.
3. 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.
4. Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not
achieved due to uneven mechanical loading.
5. 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.
6. 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).
7. Only the screws (M3 x 6mm) provided with the mounting kit should used to attach the brackets to the control
unit.
