Mounting in a 19-inch Rack using a Pre-Installed Shelf

The device can be placed on a pre-installed shelf in a 19-inch rack, as described below.
➢ To mount the device on a pre-installed shelf in the rack:
1. Make sure that your rack shelf is secured to the rack posts and in a horizontal level position
in the rack.
2. Place the device on the pre-installed shelf in the rack.
3. Position the chassis so that the front-mounting brackets are flush against the front rack
posts and that the holes of the brackets align with the holes on the posts.
4. Secure the front-mounting brackets to the rack posts using standard 19-inch rack bolts (not
supplied). This step is crucial in that it prevents the chassis from accidently sliding off the
shelf.
Elevated Operating 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 compatible with the 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.)
