Figure 38. Removing a controller
a.On the left side of the controller, press the orange release tab to the right just enough to release the handle; then, rotate the handle upward.
b.Slowly pull the handle away from the chassis to remove the controller from the bay, as shown in Figure 38.
c.Place the controller on a level surface.
Attention: After you remove a controller, wait 70 seconds before you reseat or replace the controller. Failure to do so might cause unpredictable results.
Installing a controller
Use this procedure to install a new controller as the second controller, controller B (controller A is installed in the left controller bay; controller B is installed in the right controller bay).
Attention: Make sure that the two controllers have the same cache memory capacity and options (the optional SAS host port adapter is either installed in both controllers or is not installed in both controllers). An incompatible controller will be placed in a lockout state by the other controller in the DS3200.
To install a controller in the storage subsystem, complete the following steps:
1.Read the safety information that begins on page xi and “Best practices guidelines” on page 6.
2.Make sure that the second controller has the same DIMM size, and options (such as a host port adapter) as controller A.
3.Install new
Note: Obtain the latest
