ALARM LED Indicates one of the following (check the alarm reported in the VistaNET
flashing screen):
No LEDs on but - If the Alert feature for the port is not enabled, enable it and see if any
no Ethernet
transmission for
the given drop port - Verify that the near-end and far-end ports that should be able to
- If QVLAN filtering is used, verify that the ports that should be able to
- Check that the port has not been set as a "mirror" port.
Ethernet - Verify the port's rate and duplex mode are set as desired.
communication - If an Auto-negotiation mode is selected and the negotiated duplex
through the given
port is running at a
lower rate or
duplex mode than
expected

- FPGA (Xilinx) did not boot. (Replace the unit.)
- Bad Voltage Converter (either 1.5VDC or 5VDC internal voltage
converter failed. Replace the unit.)
- Paddleboard is missing
- Unit temperature is excessive - an alarm is generated if the unit
temperature exceeds 93C.
- VCXO125 (125MHz VCXO failure. Replace the unit.)
- Clock Loss (loss of clock on both Line ports)
- VCXO38 (Clock supplied from JMUX unit is out of range.
Troubleshoot the network clock.)
- A failure in the Line Port connectivity around the ring (left-to-right
or right-to-left) for one or more TDM pipes.
- Abnormal condition on one or more enabled Ethernet drop ports.
Verify that all enabled Ethernet ports are properly connected. If
Ethernet connection is correct then it may indicate a LAN alarm
such as reception of errored frames (CRC/FCS errors), excessive
collisions, late collisions, or reception of a jabber frame. Use
VistaNET (Main Tab and Ethernet Port Statistics Tab) to
determine source of alarm. Verify the port's MDI/MDIX mode is
properly set (if applicable).
- At least one of the D-PVLAN VIDs assigned to local 'P-Trunk'
ports (see 'Advanced' tab) is matching a static QVLAN
membership assigned to another local port in Q-Access or Q-
Trunk mode.
- Two or more local ports belonging to the same D-PVLAN are set
for non-compatible Port Types. All ports on the same D-PVLAN
must be either Dot1Q (Q-type) or non-Dot1Q (P-type) ports.
alarms will be reported (or LEDs turned on). If yes, refer to the relevant
troubleshooting information above.
communicate to one another are members of the same D-PVLAN (they
must have the same D-PVLAN setting).
communicate to one another have the same static QVLAN
memberships.
mode is lower than desired, verify that Auto-Negotiation is also enabled
at the far-end's device.
