Replacing a RAID controller
Complete the following steps to replace the RAID controller that you removed
before the installation:
1. Slide the RAID controller all the way into the empty slot.
2. Close both levers until the latch locks into place.
Attention: Make sure that the levers lock into place in the storage server
chassis.
3. For the DS4100 base storage server, repeat step 1 and step 2 to replace the
second RAID controller.
Replacing a power supply
Complete the following steps to replace the power supplies that you removed
before the installation:
1. Slide one power supply into the storage server. Be sure to replace the power
supplies so that the lever on each power supply opens toward the interior of the
storage server, as shown in Figure 19 on page 31.
Attention: Be sure that the lever is pulled straight out as you slide the power
supply into the storage server, as shown in Figure 19 on page 31.
