Cause
Internal storage on the NAV device is
low.
A critical process has failed, crashing the
endpoint.
A firmware version discrepancy exists
between the NAVigator and assigned
endpoints.
The firmware upgrade process on
NAVigator or endpoints failed to
complete.
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.
The NAV device failed to receive three
consecutive IGMP queries from an IGMP
querier.
The negotiated communication speed
(Link Speed) between the NAV device
and a managed switch is lower than its
capability of 1 Gbps.
Two or more NAV devices on
the network have the same device name.
Two or more NAV devices on the
network have the same IP address.
The NAV device is receiving excessive
network traffic.
The NAVigator cannot obtain time from
the specified NTP server.
The clock to which all devices are
synchronized is changing too frequently,
for example, due to network jitter.
NAV device cannot synchronize its
PTPv2 clock with any peers.
Remedy
Reboot the NAV device. If the issue
persists, perform a software reset
that deletes files (see
RESET tab
page 40).
Reboot the NAV device. If the failure
persists, perform a mode 1 reset (see
Reset Operations
on page 15) .
Upgrade the firmware on the deviating
device.
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.
Encoder:
•
Disconnect and reconnect the video
input cable into the encoder.
•
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.
Debug network connectivity between the
NAV device and the IGMP querier (which
can be either a router or a managed
switch).
Check switch configuration and ensure
proper settings for the switch port to
which the NAV device is connected.
Change the device names affected so
that each is unique.
Change the IP addresses affected so
that each is unique.
Check the network for flooding,
also check for improper network
configuration.
Debug the network connectivity between
the NAVigator and the specified NTP
server.
Check network for flooding and correct
PTPv2 packet priority.
Ensure that network policies allow
PTPv2 packets to reach the NAV Device
from a clock master.
