SBx Linecard Status LEDs
The SBx Linecard Status LEDs display general status information about
the Ethernet line cards and controller cards. There are twelve LEDs,
numbered 1 to 12. Only LEDs 1 to 6 are used. They correspond to slots 1
to 6 in the AT-SBx8106 Chassis. LEDs 7 to 12 are not used. If the chassis
has two controller cards, the SBx Status LEDs on both cards are active.
The LEDs are defined in Table 18.
Table 18. SBx Linecard Status LEDs
LEDs State Description
1 to 12
Off Indicates that the slot is empty.
Solid Green Indicates that the Ethernet line or controller
card is operating normally.
Flashing Green Indicates that the card is booting up,
running in test mode, or loading its
configuration settings.
Solid Amber Indicates that the card is in an off-line state.
Possible causes are:
 An Ethernet line card with this LED
state may have encountered a problem
initializing the management software.
 An Ethernet line card that displays this
LED state might not be able to boot up
because the controller card does not
have the appropriate load file and
needs to be updated to the most recent
release of the AlliedWare Plus
Operating System.
 A standby master controller card that
displays this LED state may have been
disabled by the active master controller
card because they have incompatible
versions of the AlliedWare Plus
Operating System and were unable to
resolve the problem, possibly because
of insufficient free flash memory.
You may remove a line or controller card
from the chassis when it is in this state.
Flashing Amber Indicates that the card is reporting a fault
condition. Use the management commands
to determine the specific problem.
