4. Move the cam handle to the left to lock the controller canister in place.
5. Install the SFPs from the original controller in the host ports on the new controller, and reconnect
all the cables.
If you are using more than one host protocol, be sure to install the SFPs in the correct host ports.
6. If the original controller used DHCP for the IP address, locate the MAC address on the label on
the back of the replacement controller. Ask your network administrator to associate the DNS/
network and IP address for the controller you removed with the MAC address for the replacement
controller.
Note: If the original controller did not use DHCP for the IP address, the new controller will
adopt the IP address of the controller you removed.

You complete the controller replacement by placing the controller online and confirming that the
storage array is working correctly. Then, you can collect support data and resume operations.
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.
