NAV SD 511 Scaling Decoder • Troubleshooting 78
Alarm Cause Remedy
Disk Space Internal storage on the NAV device is
low. Reboot the NAV device. If the issue
persists, perform a software reset
that deletes files (see
RESET tab on
page 43).
Firmware Failure A critical process has failed, crashing the
endpoint. Reboot the NAV device. If the failure
persists, perform a
mode 1 reset (see
page 16).
Firmware Incompatible A firmware version discrepancy exists
between the NAVigator and assigned
endpoints. Upgrade the firmware on the deviating
device.
Firmware Upgrade
The firmware upgrade process on
NAVigator or endpoints failed to
complete. Retry the firmware upgrade. If it is again
unsuccessful, use Toolbelt or a web
browser to directly manage the device
and perform a unit firmware upgrade.
HDCP Error Encoder : The video input signal is
HDCP protected and HDCP negotiation
has failed.
Decoder : The incoming stream is HDCP
protected and the display connected to
the output does not support HDCP or
the HDCP version.
Encoder :
• Disconnect and reconnect the
video input cable into the encoder
(see the applicable NAV encoder
user guide at
www.extron.com ).
• Bypass video adapter cables and
make a direct HDMI male-to-male
connection.
Decoder : Check the technical
specifications of the display that is
connected to the decoder for HDCP
version support.
IGMP Failure The NAV device failed to receive three
consecutive IGMP queries from an IGMP
querier. Debug network connectivity between the
NAV device and the IGMP querier (which
can be either a router or a managed
switch).
Link Speed The negotiated communication speed
(Link Speed) between the NAV device
and a managed switch is lower than its
capability of 1 Gbps. Check switch configuration and ensure
proper settings for the switch port to
which the NAV device is connected.
Name Conflict
Two or more NAV devices on
the network have the same device name. Change the device names affected so
that each is unique.
Network Conflict Two or more NAV devices on the
network have the same IP address. Change the IP addresses affected so
that each is unique.
Network Utilization The NAV device is receiving excessive
network traffic. Check the network for flooding,
also check for improper network
configuration.
NTP Sync
The NAVigator cannot obtain time from
the specified NTP Server Debug the network connectivity between
the NAVigator and the specified NTP
server.
PTP Master Stability The clock to which all devices are
synchronized is changing too frequently,
for example, due to network jitter. Check network for flooding and correct
PTPv2 packet priority.
PTP Sync NAV device cannot synchronize its
PTPv2 clock with any peers. Ensure that network policies allow
PTPv2 packets to reach the NAV Device
from a clock master.
