Install new controller canister

After installing the battery and the host interface card (HIC), if one was initially installed, you can install the new controller canister into the controller shelf.

1. Reinstall the cover on the controller canister by sliding the cover from back to front until the button clicks.
2. Turn the controller canister over, so that the removable cover faces down.
3. With the cam handle in the open position, slide the controller canister all the way into the controller shelf.

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.
