6. Determine whether the replacement controller will serve as controller A or
controller B (controller A is inserted in the left controller bay; controller B is
inserted in the right controller bay), and then apply the controller labels for host
channels, drive channels, and numeric display to the replacement controller.
The controller labels and instructions are included with the replacement
controller. Make sure that the labels are aligned properly and do not cover any
ports or LEDs.
Attention:
Handle and install fiber-optic cables properly to avoid degraded
performance or loss of communications with devices. When working with
fiber-optic cables, do not pinch them, step on them, or locate them in aisles or
walkways. Do not overtighten the cable straps or bend the cables to a radius
smaller than 38 mm (1.5 in.).
7. Disconnect all attached interface cables from the failed controller, including the
SFP modules. Ensure that you label each cable so that you can reconnect
them correctly to the new controller.
Use the following procedure to remove the SFPs from the RAID controller that
has failed:
a. Remove the LC-LC fibre-channel cable from the SFP module. For more
information, see "Handling fiber-optic cables" on page 44.
b. Unlock the SFP module latch:
v For SFP modules that contain plastic tabs, unlock the SFP module latch
by pulling the plastic tab outward 10°, as shown in Figure 69.
