4.3 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 Section 4.3.1 on page 28
Attaching it directly to the rack’s frame using the device's mounting brackets (supplied)
that need to be attached to the chassis – see Section 4.3.2 on page 29
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, see Section 5.1 on page 31.
4.3.1 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.
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.
