Port LEDs
LEDs on the front panel of the gateway display system status and alert you to troubleshoot the
gateway. These LEDs include the following:
z
T1/E1 port LEDs—Two LEDs (yellow and green) on top of each T1/E1 port indicate the status of
each T1/E1 port that is labeled from 0 through 15 . At any one time, only one of the LEDs is lit. For
more information on LEDs, see “T1/E1 Ports” on page 6.
z
Copper Ethernet port LEDs—Two LEDs (yellow and green) on the top of each copper Ethernet
port indicate the status of each Copper Ethernet port and are labeled as COPPER with
ETHERNET 0 through ETHERNET 2. For more information on LEDs, see “Ethernet Ports” on
page 8.
z
Optical Ethernet port LEDs—Two LEDs (yellow and green) on top of each SFP indicate the status
of each SFP and are labeled as SFP with ETHERNET 1 and ETHERNET 2 . For more information
on LEDs, see “Ethernet Ports” on page 8.
System LED
One system LED on the center of the front panel indicates the status of the gateway. Green
indicates that the gateway is functioning normally. Red indicates a critical condition that can cause
the gateway to stop functioning. Yellow indicates a non-critical or minor condition that requires
monitoring. For more information, see System LED on page 54.
Chassis and Interface Alarm Messages
When the gateway detects an alarm condition, it lights the red or the yellow alarm LED. To view a
more detailed description of the cause for the alarm, issue the show chassis alarms command:
cli@BX7000>
show chassis alarms
There are two classes of alarms:
z
Chassis alarms—Indicate a problem with a chassis component such as power supply and board
temperature, as described in Table 16 on page 54.
z
Interface alarms—Indicate a problem with a specific network interface, as described in Table 17.
In Table 17 on page 55, the text in the column labeled CLI Message appears in the output from the
show chassis alarms command.
