b. Rotate the cam latch down as far as it will go. For horizontal modules, rotate the cam away from the
module as far as it will go.
c. Remove the blanking module.
6. Install the I/O module:
a. Align the I/O module with the edges of the controller module slot opening.
b. Gently slide the module all the way into the into the slot, and then rotate the cam latch all the way up to
lock the module in place.
7. Cable the I/O module.
If the I/O module is a NIC, cable the module to the data switches.
If the I/O module is a storage module, cable it to the NS224 shelf.
Make sure that any unused I/O slots have blanks installed to prevent possible thermal
issues.
8. Reinstall the controller module into the chassis.
If you have DC PSUs, reconnect the cable blocks to the PSUs.
9. Rotate the cable management tray up to the closed position.
10. Reboot the controller from the LOADER prompt: bye
This reinitializes the PCIe cards and other components and reboots the node.
11. Give back the controller from the partner controller: storage failover giveback -ofnode target_node_name
12. Repeat these steps for controller B.
13.
Restore automatic giveback if you disabled it by using the
storage failover modify -node local
-auto-giveback true
command.
14.
If AutoSupport is enabled, restore/unsuppress automatic case creation by using the
system node
autosupport invoke -node * -type all -message MAINT=END
command.
15. If you installed a storage I/O module, install and cable your NS224 shelves, as described in
Hot-adds a
shelf
.
Option 2: Add an I/O module in a storage system with no empty slots
You can change an I/O module in an I/O slot in a fully-populated system by removing an existing I/O module
and replacing it with a different I/O module.
1. If you are:
Replacing a… Then…
NIC I/O module with the same the
same number of ports
The LIFs will automatically migrate when its controller module is shut
down.
