Removing and Replacing an Upper Drive Bay Metal Shield
To remove a metal shield from one of the upper drive bays:
c. Grasp the metal shield by it's tab located in the center of the front surface.
d. Pull the shield out by the tab in a straight motion to avoid tearing the tab from the shield.

General Installation Guidelines

When you install a drive, you connect two cables—a DC power cable from the power supply and a data cable—to the back of the drive. The other end of the
data cable will connect to either an expansion card or to the system board. Most connectors are keyed for correct insertion; that is, a notch or a missing pin on
one connector matches a tab or a filled-in hole on the other connector.

Power Cable Connectors

1 power cable
When connecting an IDE data cable, align the tab on one connector with the notch on the other. When disconnecting an IDE data cable, grasp the colored
pull-tab and pull until the connector detaches.
When you connect two IDE devices to a single IDE data cable and configure the devices for the cable select setting, the device attached to the last connector
on the data cable is primary or the boot device, and the device attached to the middle connector on the data cable is the secondary device. See the drive
documentation in your upgrade kit for information on configuring devices for the cable select setting.
When connecting a SAS or SATA cable, hold the cable by the connector at each end and press firmly into the connector. When disconnecting a SAS or SATA
cable, hold the cable by the connector at each end and pull until the connector detaches.
