Digicast Media Router Serial IP (SIP): CMR-5910 (MG-SIP) & CMR-5920 (MR-SIP) Revision A
Troubleshooting MN/MDRTRIPDC.IOM
SYMPTOM: Cannot ping the device
If the E-LINK LED is illuminated but the user cannot ping the device, the most
likely causes are incorrect settings for the IP address or subnet mask. Ensure the
device and the PC are set with unique IP addresses that are in the same subnet.
If the device and the PC are not in the same subnet, then both the device and PC
must have a valid “Default Gateway” defined so that non-local traffic will be
redirected to this device for routing the IP messages between the two devices.
SYMPTOM: Device will not synchronize with an IRD or Encoder
The device may be connected directly from an RS-422/RS-530 output port to an
RS-422/RS-530 input port on a modem. If the modem will not lock, the most
likely cause is the data rate on the device or modem are not set correctly.
SYMPTOM: Device reports dropped packets
The most likely cause of this problem is the incoming data on a route or all routes
exceeds the configured egress bandwidth.
To remedy the problem:
•
Look at the route statistics for the device and identify the routes with
dropped packets.
•
Lower the rate of the incoming data or increase the maximum bandwidth
assigned to the route if QoS is set.
SYMPTOM: Device has a RED Alarm displayed
The most likely cause of the ALARM LED is the maximum bandwidth has been
exceeded. Please refer to the previous item to troubleshoot this problem.
