Getting Started
Preparing for the Installation
Alcatel-Lucent Enterprise products must be installed by a professional installer. It is the responsibility of
the installer to comply with product specifications and all applicable local and national codes.
When preparing for installation, unpack the product as close as possible to the location where it will
be installed.
Elevated Operating Ambient Temperature
If installed in a closed or multi-rack assembly, the operating ambient temperature of the rack
environment may be greater than the room’s ambient temperature. Therefore, consideration should be
given to the maximum rated ambient temperature (Tmra). When operating at 74°C ambient
temperature the switch must be installed in a suitable closed rack or cabinet enclosure.
Reduced Air Flow
Installation of the equipment should be such that the amount of air flow required for safe operation of
the equipment is not compromised. Refer to
“Providing Air Flow and Minimum Recommended
Clearances” on page 20 for more information.
Mechanical Loading
Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to
uneven loading.
Circuit Overloading
Consideration should be given to the connection of the equipment to the supply circuit and the effect
that overloading of circuits could 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 (e.g., use of power strips).
Caution: An operating Omniswitch may be hot to the touch.
