Spine Module Management LEDs
Each SFS 7012 spine module has three management LEDs:

•
Stat:
–
Green
indicates that a management board is present.
–
Off
indicates that no management board is present.
•
Act:
–
Green
indicates that management board is in the active mode. In a redundantly-managed
system, this would indicate the master spine.
–
Off
indicates that the management board is in the standby mode (if the STAT LED is
Green
).
In a redundantly-managed system, if the Capable LED is also Green, this would indicate the
slave spine.
•
DDR:
–
Green
indicates that the switch is capable of running at DDR speeds.
–
Off

Hot Swapping Components
Hot Swapping Spine and Leaf Modules
Note
Following are the general guidelines for hot swapping leaf and spine modules:
Caution
Be certain that the managed spine to be hot swapped is a that same firmware level as all other
components in the SFS 7012. A hot swap of a managed spine with another firmware level will cause a
disruptive reboot (i.e., I/O traffic is interrupted).
