tray should be aligned to four screw holes in the chassis.

screw to 8 in-lb (0.9 N·m) of torque.

Replacing Fabric 2 Modules with Fabric 3 Modules
If you are running Cisco NX-OS 8.3(1) or a later release on a Cisco Nexus 7710 switch, you can replace all
the Fabric 2 modules with Fabric 3 modules. You can replace the modules during operations if you replace
each module within a couple of minutes so that the switch can maintain its designed airflow. The replacement
procedure is non-disruptive to switch operations if there is at least one fabric module installed and operating
in the switch while you replace the other fabric module.
To replace Fabric 2 modules with Fabric 3 modules, follow these steps:
Step 1 Verify that the switch is running Cisco NX-OS Release 8.3(1) or a later release.
Step 2 Replace the Fabric 2 module that is in the lowest numbered fabric slot.
Step 3 Enter the show module xbar command, as shown in the example below, to display the types of fabric modules installed
in the fabric slots.
