(1) Controller canister
(2) Cam handle
3. Move the cam handle to the left to lock the controller canister in place.
4. Insert any SFP+ transceivers, and connect cables to the new controller.
Step 7: Complete adding a second controller
Complete the process of adding a second controller by confirming that it is working correctly, reinstall the
duplex NVSRAM file, distribute volumes between the controllers, and collect support data.
Steps
1. As the controller boots, check the controller LEDs and the seven-segment display.
When communication with the other controller is reestablished:
◦ The seven-segment display shows the repeating sequence OS, OL, blank to indicate that the
controller is offline.
◦ The amber Attention LED remains on.
◦ The Host Link LEDs might be on, blinking, or off, depending on the host interface.
