Indicator LEDs
Indicator LEDs
Indicator LEDs indicate whether AC power is present and if a card is operating normally. LEDs are
visible when the router front door is closed. In the following sections, LEDs are listed in the order
they appear on the cards, from top to bottom.
Power Supplies
The NV6257 contains up to eight PS6000 power supply modules and the NV8000 contains up to
four PS8010 power supply modules. Each power supply module has five green LEDs on the front.
The LEDs indicate that the five +48 VDC outputs of the five branch circuits are present. All five
LEDs should be lit at all times when AC power is present. If any LED is off, either the power sup-
ply has failed or the branch circuit is shorted. If any are not, it is likely that the corresponding
branch circuit has failed. When the power supply output voltages are measured at the test points,
the voltage should be approxi48 VDC under a full load. If modules have been removed
from the frame or options are not installed, some or all of the test point voltages could be somewhat
higher than +48 VDC.
Control Cards
The LEDs on the control card(s) can be monitored to determine whether the card is operating nor-
mally. The LEDs are listed in the order they appear on the card:
Input, Crosspoint, and Output Cards
The LEDs on the input, output, and crosspoint cards can be monitored to determine whether the
cards are operating normally. The LEDs are listed in the order they appear on the cards:
LED Indicator
Indicator Function
Red (low battery)
Normally OFF. If lit, indicates that the battery needs replacing. See
Red (alarm)
Normally OFF. If lit, indicates a problem or fault. Check the external reference
signals. If that does not resolve the problem, refer to the system status window in
UniConfig for additional information. If you cannot resolve the problem, call
NVISION Technical Support. For contact information, see page iii.
Amber (active)
Normally ON. Indicates the card is the active control card. On the standby control
card, this LED should be OFF.
Green (health)
Normally ON. Indicates the card has power and is operating normally.
LED Indicator
Indicator Function
Red (alarm)
Normally OFF. If lit, it indicates a problem. Replace the card or call NVISION
Technical Support. For contact information, see page iii.
Green (Power)
Normally ON. Indicates the card has power and is operating normally.
Amber
Normally ON. Indicates the card is operating normally.
Green
Normally ON. Indicates good communication with the control card.
Red
Normally OFF. If lit, indicates that communication is not working properly; the
communication with the control card is “bad.”
