Dell PowerVault DP100 - Manual (Page 37)

Interface Cables
Most interface connectors are keyed for correct insertion. Keying ensures that the pin-1 wire in the cable connects to pin 1 in the connectors on both ends.
When you disconnect an interface cable, take care to grasp the cable connector, rather than the cable itself, to avoid stress on the cable.
Drive Cable Configurations
Your system can accommodate many different drive configurations, each with specific cable requirements. Table 3 -1 shows the cable requirements for common
drive configurations.
Table 3-1. Drive Cable Configuration
DC Power Cables
Each drive must connect to a DC power cable from the system power supply. These power cables are used for the 3.5-inch diskette drive, 5.25-inch devices,
and hard drives.
Diskette Drive
Removing a Diskette Drive
1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
2. Open the system. See Opening the System .
3. Disconnect the power cable and the interface cable from the diskette drive. See Figure 3 -5 .
4. Remove the two screws that secure the diskette drive in the externally accessible drive bay. See Figure 3 -5 .
5. Slide the diskette drive forward out of the drive bay.
Installing a Diskette Drive
1. Unpack the drive and prepare the drive for installation.
For instructions, see the documentation that accompanied the drive.
2. Slide the diskette drive into the externally accessible drive bay.

NOTICE: To avoid electrical damage to internal system components, install a cover connector on any unused connectors on hard-drive power cables.
CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system.
Before performing any procedure, see your Product Information Guide for complete information about safety precautions, working inside the
computer, and protecting against electrostatic discharge.
