About the Fabric Controllers
Refer to “Fabric Controller Modules” on page 18 for more specific information about this module.
About a Failed Fabric Controller
If you believe a fabric controller module has failed, contact technical support.
Refer to
“Fabric Controller LEDs” on page 70 and “Monitor the Cards” on page 79 for monitoring
information.
Locating a Failed Fabric Controller
The fabric controllers are located on the front of the chassis, behind the bezel cover. Refer to Figure 1-1
for a diagram of the chassis. The slots are labelled on the chassis.
Considerations Before Removing a Fabric Controller Card
Before removing a fabric controller card from either a node or a core slot of the Topspin 270, keep the
following in mind:
1. The fabric controllers cards in the core slots are paired to the Management Interface modules on the
other side of the chassis.
•
Fabric controller card in slot 11 is paired to the Management Interface module in slot 15.
• Fabric controller card in slot 12 is paired to Management Interface module in slot 16.
Therefore, before removing a fabric controller from a core slot, make sure that the second pairing
of Fabric Controller/Management Interface module is intact.
2. Removing the fabric controller in the core slot that is currently acting as master will cause a
fail-over to the standby pair of fabric controller/Management Interface modules.
It takes up to 3 seconds for the standby fabric controller to become a new master.
a.
If you are removing a fabric controller card from a node slot, the card will be located in slots 9,
10, 13, and 14 (marked on the chassis).
b. If you are removing a fabric controller card from a core slot, the card will be located in slots 11
or 12.
Removing a Fabric Controller
1. Ground yourself appropriately.
2. Verify that you have a means of covering the slot before removing the module. Do not remove the
module unless you have a replacement or a blanking panel for the slot, as overheating may occur.
3. Remove the bezel cover from the front of the switch.
4. Determine whether the Fabric Controller you want to remove is installed in a Core slot or a Node
slot. Refer to Figure 1-1 for a diagram of the chassis.
If you are removing a Fabric Controller from one of the core slots, make sure that the redundant
core Fabric Controller is functional.
Removal of the Fabric Controller currently acting as master will cause a fail-over. It takes up to 3
seconds for the standby fabric controller to become a new master.
