Battery Replacement
The router can be operated safely with the door opened for short periods of time. If the filter is
only lightly contaminated, clean the filter by vacuuming loose debris or by blowing air from the
inside outward. Rinse filters badly loaded with debris with cold water or wash them with warm
water and mild detergent. Be sure the filter is completely dry before re-installing it.
Battery Replacement
If the red ‘Low Battery’ indicator (LED 8) on the control card is lit, the battery located on the front
edge of the control card must be replaced. Grasp the exposed edge of the battery with your
fingers and pull it towards you to remove it.
Call
Grass Valley
for replacement battery information.
When you insert the new battery, be careful to observe the correct polarity. The “+” side of the
battery must be farther away from the circuit board.
Note:
The battery is a 3V Panasonic CR2330 coin type battery or its equivalent.
Troubleshooting
Many system problems are caused by easily corrected errors, such as poor quality or missing
input or reference signals, incorrect configuration, and so on. This section lists common prob-
lems and their solutions in the most likely order of occurrence. Refer also to the
About the
NV8500 Series Routers
on page 1 for an overview of the system and its major components. Try
troubleshooting the system yourself, and if you are not successful, call
Grass Valley
Technical
Support.
If a problem is caused by a bad circuit board, swapping the bad board with a replacement circuit
board is the quickest solution. To order replacement boards or other components, contact Grass
Valley.
IMPORTANT
Do not use a metallic tool to remove the battery.
CAUTION
To prevent explosion of the battery and possible equipment damage or harm to
personnel, be sure the battery is oriented with the correct polarity.
Symptom
Possible Causes and Solutions
System not powering up.
Verify that the power cord(s) are plugged into the frame and the AC
power source. Use a voltmeter to verify the presence of power.
One or a few cards or PS8100/
PS8300 power supply modules
are not powering up or not oper-
ating properly.
Check that the card or module is fully seated in the frame.
Reset the card or module by reseating it in the frame.
Check that all five green LEDs on the front of the PS8100 or PS8300
power supply modules are lit. If an LED is not lit, it indicates a branch
circuit may be faulty, which could affect only certain modules in the
frame. Replace the power supply module.
