SBx Linecard Status LEDs
The SBx Linecard Status LEDs display general status information about
the Ethernet line cards and controller cards. There is one LED for each
slot. 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 that displays 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 the cards 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.
