2.3.2 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 (refer to 'Using a Pre-installed Rack
Shelf' on page 16).
Attaching it directly to the rack’s frame using the device's mounting brackets (supplied)
that need to be attached to the chassis (refer to 'Using Mounting Brackets' on
page 17).
Rack Mount Safety Instructions
When installing the chassis in a rack, implement the following safety
instructions:
• 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, refer to Section ‘Connecting to Earth
(Ground)’ on page 19.
2.3.2.1 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.
¾ To mount the device on a pre-installed shelf in the rack:
1. Before installing it in the rack, ensure that you have a pre-installed rack shelf on which
the device can be placed.
2. Place the device on the pre-installed shelf in the rack.
