SNMP NB20E and SNMP NB25E LEDs
The LEDs on the bridge front panels in the Device View are animated to
reflect the state of the LEDs as of the last poll cycle. The LEDs turn on or off to
match the bridge on the network. For detailed information on the LED
definitions, and the operation of your bridge, refer to the documentation that
accompanied your bridge. The following is a general definition of specific
LEDs for the SNMP NB20E and SNMP NB25E bridge model types.
ON LINE
When this green LED is on, the bridge is receiving power, and has completed
its power up self test. The bridge is capable of forwarding packets.
STAND BY
When this yellow LED is on, the bridge is in “STANDBY” mode and not
capable of forwarding packets across the link.
XMT (Transmit)
When this green LED is flashing, the bridge is transmitting packets to that
network segment.
RCV (Receive)
When this yellow LED is flashing, the bridge is receiving data packets from
that network segment.
CP (Collision Present)
When this red LED is flashing, a collision is occurring on that network
segment.
