5. Locate the Power Distribution board at the back of
the tub above the Control Panel CPU module.
6. Using the Power Supply Indicators, identify the
power supply that has failed. If a power supply is
not providing power, or is not installed, the Power
Supply Indicator is not lit.
If all the Power Supply Indicators are lit, check the
cables between the power supplies and the Power
Distribution board.

To Identify a Failed Cooling Fan
1.
Press
HOME
>
Status
and identify which cooling
fan is reporting a failure.
If you have the Redundant Power option installed,
cooling fans 1 and 2 are located in the Primary
Power Supply module and cooling fans 3 and 4 are
located in the Secondary Power Supply module. If
you do not have the Redundant Power option, only
the Primary Power Supply module is present with
cooling fans 1 and 2.

2. Place a small piece of paper in front of each cooling
fan in the Power Supply Module to determine if the
fan is moving air.
3. If a cooling fan is not moving air, or is moving much
less than the other fans, that Power Supply module
must be replaced. Refer to
To Replace a Control
Panel Power Supply on page 107.
If all the cooling fans appear to be moving air
properly, check that the cables between the Power
Supply module and the Power Distribution board
are not damaged.
Panel Communications Hub Tests
The Panel Communications Hub (PCH) tests allow you
to test the functionality of the PCH communication links
with the various components of the switcher. Some of
these tests require the use of a loopback adapter on the
communications port.
To Perform a PCH Tx/Rx Test
The PCH Tx/Rx test allows you to test the various serial
communications ports on the control panel. This test
helps to diagnose communication problems with external
devices that you may be having on a particular serial
communications port on the control panel.
A loopback adapter is required to be connected to the
port you want to test.

2.
Use the
Com Port
knob to select there serial port
that you want to test.
• REMOTE X — test one of the remote ports.
•
ExtLnk X
— test one of the external link ports.
3.
Use the
Mode
knob to select the transmission
standard that you want to use to test the selected
port.
• RS-422 — use the RS-244 (TIA/EIA-422)
transmission standard.
• RS-422 Null — use the RS-422 (TIA/EIA-422)
transmission standard configured for a null
modem cable.
•
RS-232
— use the RS-232 (TIA/EIA-232)
transmission standard.

The outcome of the test is reported on the menu as passed
or failed.
To Perform an LVDS Test
The Low Voltage Differential Signalling (LVDS) test
allows you to test the various communications between
the Panel Communications Hub (PCH) and all the Panel
Module Controllers (PMC) installed on the switcher.
This test includes both internal and external modules.
Note: Some external devices contain multiple modules and will
show up as more modules than devices connected to a link.

test the link to an internal panel module ( Intern ),
or an external panel module (
