Rack Mount Safety Instructions
When installing the chassis in a rack, adhere the following safety instructions:
• 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.)
4.2.1 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.
