Install new controller canister (simplex)

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

Before you begin

Steps

  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. Determine how you will assign an IP address to the replacement controller, based on whether you connected its Ethernet port 1 (labeled P1) to a network with a DHCP server and on whether all drives are secured.
    Using DHCP server? All drives secured? Steps
    Yes No The new controller obtains its IP address from the DHCP server. This value might be different than the original controller's IP address. Locate the MAC address on the label on the back of the replacement controller, and contact your network administrator with this information to obtain the IP address that was assigned by the DHCP server.
    Yes Yes The new controller obtains its IP address from the DHCP server. This value might be different than the original controller's IP address. Locate the MAC address on the label on the back of the replacement controller, and contact your network administrator with this information to obtain the IP address that was assigned by the DHCP server. You can then unlock the drives using the command line interface.
    No No The new controller adopts the IP address of the controller you removed.
    No Yes You must set the IP address of the new controller manually. (You can reuse the IP address of the old controller or use a new IP address.) When the controller has an IP address, you can unlock the drives using the command line interface.

    After the drives are unlocked, the new controller will re-use the original controller's IP address automatically.
