LED activity during normal operations
Refer to Table 1-2 for a description of SP Switch Router Adapter card LED activity during
normal run time operations.
Table 1-2. SP Switch Router Adapter media card LEDs
LED Description
PWR ON This green LED is on when 5 volts are present. Both power LEDs,
5V and 3V, can be on simultaneously.
3V This green LED is on when 3 volts are present.
RX HB (green) During normal run-time operations, this green LED blinks a
“heartbeat” pattern for the receive side CPU. The beat is a long off,
short on-off-on pattern .
In the pattern, the LED goes off for 1/2 second, comes on for 1/4
second, goes off for 1/4, comes on for 1/4, and then begins the
pattern again by going off for 1/2 second.
• RX ST0 (green)
• RX ST1 (amber)
• RX ERR (amber)
These three LEDs
light in different
combinations to
indicate
five operating states
for the receive port.
• ON STATE_0 - These three LEDs are on during
• ON hardware initialization.
• ON
• OFF STATE_1 - Bottom two amber LEDs go on during
• ON software initialization, show receive port
• ON is waiting for configuration parameters.
• ON STATE_2 - Middle amber LED goes off when
• OFF configuration parameters are in place and the
• ON receive port is ready to be connected.
• OFF STATE_3 - Bottom amber LED goes on to show that
• OFF the receive port is connected and the card is
• ON ready to be on line
• OFF STATE_4 - These three LEDs are off to show receive
• OFF port is online and running/routing.
• OFF
MD RCV (amber) This amber LED lights when data comes into the receive media port
from an external source.
SW XMIT (amber) This amber LED lights when the receive media port sends data to the
SP Switch Router switch core (via the serial daughter card).
TX HB (green) This green LED blinks a “heartbeat” pattern for the transmit side
CPU, the beat is a long off, short on-off-on pattern during normal run
time operations.
In the pattern, the LED goes off for 1/2 second, comes on for 1/4
second, goes off for 1/4, comes on for 1/4, and then begins the
pattern again by going off for 1/2 second.
