Dell HR675 owner manual Installing a SAS Controller Card

4Open the expansion card latch adjacent to the slot (see Figure 3-20).

5Disconnect the SAS cable, LED cable, and RAID battery cable (if applicable) from the SAS controller card.

6Grasp the card by its top corners and ease it out of its connector (see Figure 3-20).

NOTE: If you are removing the card permanently, install a filler bracket in the empty card slot.

NOTE: Filler brackets must be installed over empty expansion card slots to maintain Federal Communications Commission (FCC) certification of the system and protect against electromagnetic interference. The brackets also keep dust and dirt out of the system and aid in proper cooling and airflow inside the system.

7Remove the RAID battery from the battery holder, if applicable (see "Installing and Removing a RAID Battery" on page 100).

8Close the expansion card cover (see Figure 3-7).

9Replace the system cover (see "Installing the System Cover" on page 67).

10Reattach any peripherals you disconnected, then connect the system to the electrical outlet.

11Turn on the system and attached peripherals.
