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 indicates that the switch is not capable of running at DDR speeds (i.e., SDR only).

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).
