Dell HR675 owner manual Hard Drives, Installing a Non-Redundant Power Supply

Installing a Non-Redundant Power Supply

1Slide the power supply into the back of the chassis until the power supply release tab snaps into place (see Figure 3-10).

2Replace the screw to secure the power supply to the system (see Figure 3-10).

3Connect all power cables to the system board, drives, and SAS backplane (if installed).

Ensure that all power cables are routed properly to prevent the cables from becoming pinched or crimped.

4Replace the processor airflow shroud (see "Installing the Processor Airflow Shroud" on page 72).

5Replace the system cover (see "Installing the System Cover" on page 67).

Hard Drives

NOTICE: Combining SATA and SAS hard drives in the same system configuration is not supported.

Depending on your system configuration, your system supports up to four

3.5-inch SATA or SAS hard drives installed internally (see Figure 3-13) or at the front of the system (see Figure 3-11). Hard drives installed in your system are connected to the system board, an optional controller card, or to the SAS backplane (requires a SAS controller card). Only hard drives installed in the hard drive bays at the front of the system can be used as hot-pluggable.

Removing a Hot-Pluggable Hard Drive

1Remove the front bezel (see "Removing the Front Bezel" on page 63).

2From the RAID management software, prepare the drive for removal and wait until the hard drive indicators on the front of the drive carrier signal that the drive can be removed safely. See your SAS/RAID controller documentation for information about hot-pluggable hard drive removal.

If the hard drive is online, the green activity/fault indicator flashes as the drive is powered down. When both drive indicators are off, the drive is ready for removal.
