Step 1: Prepare To Replace Controller (Duplex) - Lenovo ThinkSystem DE Series Manual

This procedure is for like-for-like shelf IOM hot-swaps or replacements. This

means you can only replace an IOM12 module with another IOM12 module or
replace an IOM12B module with another IOM12B module. (Your shelf can have
two IOM12 modules or have two IOM12B modules.)
What you'll need
• A replacement controller canister with the same part number as the controller canister you are
replacing. (See step 1 to verify the part number.)
• An ESD wristband, or you have taken other antistatic precautions.
• #1 Phillips screwdriver.
• Labels to identify each cable that is connected to the controller canister.
• A management station with a browser that can access ThinkSystem System Manager for the
controller. (To open the System Manager interface, point the browser to the controller's domain
name or IP address.)

3.2.2. Step 1: Prepare to replace controller (duplex)

Prepare to replace the controller by verifying that the replacement controller canister has the
correct FRU part number, backing up the configuration, and collecting support data. If the
controller is still online, you must take it offline.
Steps
1. Unpack the new controller canister, and set it on a flat, static-free surface.
Save the packing materials to use when shipping the failed controller canister.
2. Locate the MAC address and FRU part number labels on the back of the controller canister.
(1) MAC address: The MAC address for management port 1 ("P1"). If you used DHCP to obtain
the original controller's IP address, you need this address to connect to the new controller.
(2) FRU part number: This number must match the replacement part number for the currently
installed controller.
3. From ThinkSystem System Manager, locate the replacement part number for the controller
canister you are replacing.
