Rack-mount Considerations
A. 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, consid-
eration should be given to installing the equipment in an environment compatible
with the maximum ambient temperature (Tma) specified by the manufacturer (see
Specifications information in this document).
B. 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. To ventilate the
system normally and avoid overheating, leave at least 1 inch (2.5 cm) on each side
(including top and bottom) of the OAT100R. Do NOT stack other equipment on the
top of the OAT100R.
C. 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 overcurrent
protection and supply wiring.
D. Reliable Earthing
Maintain reliable earthing of rack-mounted equipment. Particular attention should be
given to supply connections other than direct connections to the branch circuit (e.g.
use of power strips).
E. Mains Outlet Earthing
The apparatus with Class I construction must be connected to a mains socket outlet
with a protective earthing connection.

c) At the prompt, type the number that corresponds to the appropriate output mode
and press Enter.
The system will confi rm your selection, for example:
Output mode is set: IP
11. The next step depends on the output mode:
• If you are setting up the system for RF output, continue with step 12.
• If you are setting up the system for IP output, go to step 13.
12. (RF output only) Complete OAT100R RF output configuration as follows:
a) If the Command > prompt is on display, type setup and press Enter to access
the Setup Menu.
b) At the Setup Command > prompt, type rf and press Enter. The system will
display a list of RF mode options, followed by a prompt for a selection:
Select a new RF mode [2]:
c) At the prompt, either press Enter to accept the default value in square brackets, or
type the number that corresponds to the appropriate RF mode and press Enter.
d) At the Enter a new RF channel [2]: prompt, either press Enter to accept
the default value in square brackets, or type a new RF start channel number and
then press Enter.
e) At the Enter number of channels [4]: prompt, either press Enter to
accept the default value in square brackets, or type the applicable number of
channels (Maximum = 4) and then press Enter.
The system will display an overview of the settings, for example:
RF config:
Mode 2, 256-QAM-B, RF: 6 MHz, 5.36 MSps
RF channels:
7 8 9 10
f)
Connect RF OUT on the OAT100R rear panel to the RF distribution center
combiner, and balance the RF signal so that the signal level at the TV(s) is
between 0 to +7 dBmV.
Caution: For proper system performance, the OAT100R signal level at
the TV input (ANTENNA IN) must be between 0 to +7 dBmV. Note that
additional equipment (i.e., attenuators) may be required to adjust the
signal level.
g) Go to step 14.
