19-Inch Rack Mounting

The device can be installed in a standard 19-inch rack by implementing one of the following
mounting methods:
■ Placing it on a pre-installed shelf in a 19-inch rack – see
below
■ Attaching it directly to the rack's frame using the device's mounting brackets (supplied) that
need to be attached to the chassis – see
Rack Mount Safety Instructions: When installing the chassis in a rack, implement the
following safety instructions:

Using a Pre-Installed Rack Shelf

The procedure below describes how to place the device on a pre-installed shelf in a 19-inch rack.
Elevated Operating Ambient Temperature: If installed in a closed or multi-unit
rack assembly, the operating ambient temperature of the rack environment may be
greater than room ambient temperature. Therefore, consideration should be given to
installing the equipment in an environment with maximum ambient temperature
(Tma) of 40°C (104°F).
Reduced Air Flow: Installation of the equipment in a rack should be such that the
amount of air flow required for safe operation on the equipment is not compromised.
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 over-current 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). For earthing the
device, see Grounding the Device
