Installing the 20-Slot Rackmount Chassis

Install the chassis first before installing any modules into a 20-Slot Rackmount Chassis. When installing the chassis, be sure to observe the following precautions to prevent electrical or mechanical damage:

1.Protect the chassis from exposure to sunlight and electrical or magnetic fields.

2.Ensure that the equipment rack remains stable, even with the addition of the chassis and its associated cabling.

To install 20-Slot Rackmount chassis:

1.Have four #10 screws and four clip nuts available (hardware may vary depending on rack type). The rest of the hardware is supplied with the unit.

2.Locate a suitable location in the rack for installation and secure the clip-nuts onto the mounting rails. Use screws to attach the chassis to the rack.

3.Plug the chassis into a reliable, filtered power source.

4.Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the Black Box.

5.Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.

6.Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.
