8. Use the Configuration Update action of the TSM Service Application to download 
the T0569AAA M6770CL configuration to the nearest Y-fabric cluster switch. For 
detailed steps, refer to Using the TSM Service Application to Download the 
ServerNet II Switch Firmware or Configuration on page 4-99. 
9. Use the Firmware Update action of the TSM Service Application to download the 
T0569AAA M6770 firmware file to the nearest Y-fabric cluster switch. For detailed 
steps, refer to Using the TSM Service Application to Download the ServerNet II 
Switch Firmware or Configuration on page 4-99.  
10. Use the TSM Service Application to perform a hard reset of the nearest Y-fabric 
cluster switch:
a. From the Cluster tab, click the plus (+) sign next to the External ServerNet Y 
Fabric resource to display the Switch resource.
b. Right-click the Switch resource and select Actions. The Actions dialog box 
appears.
c. In the Actions dialog box, choose Hard Reset, and click Perform Action.
11. Use the TSM Service Application to verify the operation of the Y-fabric cluster 
switch.
Note. Note the following considerations for downloading the T0569AAA configuration:
•
Downloading the configuration disrupts ServerNet communications across the Y-fabric 
cluster switch.
•
The T0569AAA configuration does not support Configuration 2 (0x10001). If the 
cluster switch uses Configuration 2, you must change the configuration tag to 
Configuration 1 in order to download the T0569AAA configuration. The guided 
procedure allows you to change the configuration tag.
Note. If the cluster switch is currently running T0569AAA firmware, updating the 
configuration can change the fabric setting. The fabric setting (X or Y) will change to a 
default setting (X) when the T0569AAA configuration is loaded in the switch. The 
T0569AAA configuration normally should be loaded on the cluster switch only when a 
configuration fallback is being performed.
If the cluster switch is installed on the external Y fabric, you need to reconfigure the fabric 
setting in the cluster switch back to Y after the fallback. Until you perform this action, 
ServerNet traffic through the cluster switch will remain disabled.
You can use the Set LED to { X | Y } Side action in the TSM Service Application to correct 
the fabric setting.
If the cluster switch is currently running T0569AAB firmware, the configured fabric setting 
(X or Y) remains unchanged when either the T0569AAA (fallback) or the T0569AAB 
configuration is loaded in the cluster switch.
