Installation
Cabling Power and Ground
3. If you are mounting the chassis in a 23-inch rack, use the four screws that
come with each extension bracket (provided with the chassis) to attach
the brackets to the mounting ears.
4. Attach the chassis to the rack by inserting four screws on each side of the
chassis through both the mounting ears or extensions on the side of the
chassis and the rack rails.
Cabling Power and Ground
The BROAD way chassis accepts a DC power feed directly into the chassis.
NOTE:
To power the BROAD way system from an AC supply (110–230 VAC), you must
use an external AC-to-DC converter.
As when installing any additional equipment within an existing or planned rack environment, consider
how powering the
BROAD way chassis will impact the overall loading of the branch circuit used at the
rack. A fully loaded BROAD way chassis requires approximately 160W to power the system. When
installing in a rack, make sure that a reliable ground (earth) path is maintained; the BROAD way chassis
is intended to be connected to a good Earth ground such as that provided by building steel, a cold water
pipe or, preferably, a properly constructed ground plate or bonding network.
To connect power and ground to the BROAD way chassis:
1. Verify that the ON/OFF ( O/I ) switch on the back of the chassis is set to OFF ( O ).
2. Connect the Earth ground stud on the back of the chassis to a suitable Earth ground as
previously described.
