 DDR (Spine Module Only):

• 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).

Subnet Manager License Key Activation

If the user has purchased the InfiniBand Fabric Suite 2008 package, in order to

activate the subnet manager the user must acquire a subnet manager (SM) license

key from QLogic Technical Support. In order to do this, the user must first find the

globally unique identifier (GUID) for the FRU to be used as the master SM. The

GUID can be:

 Retrieved from the label on the spine.

 Retrieved via software using the Chassis Viewer GUI or the command line

interface (CLI).

For detailed information on retrieving the FRU GUID and acquiring a license key,

please refer to the applicable switch quick start guide.

Shut Down Procedures

In order to shut down the switch:

1. Power down the switch by removing the power cords from the AC power inlets.

Hot Swapping Components

Hot Swapping Leaf/VIO and Spine Modules

NOTE: Following are the general guidelines for hot swapping leaf and spine

modules:

• Hot swap one module at a time, allowing the chassis to completely update it

before hot-swapping the next module. The module update is complete when it

becomes visible within the Chassis Viewer GUI. Listed below are the

approximate times to fully update each module type:

• Spines modules: up to 4 minutes

• Leaf/VIO modules: up to 2 minutes

A general recommendation is to hot swap beginning with leaf modules, then VIO

cards, then spine modules with the managed spine(s) being last.

• When a management spine is hot swapped, the rest of the chassis will continue

to move packets without interruption.
