Remove thefour hard disk access panel screws (see Figure 124). Place the panel and screws in a safelocation.5 Install the hard disk cage in the BCM200 main unit.a Insert the hard disk cage through the hard disk access panel in the back of the BCM200.b Position the hard disk cage in front of the cage chassis mounting points. The hard diskcage lift tab is at the rear of the hard disk cage.c Slide the hard disk cage in the direction shown in Figure 126 until the unit attaches to thechassis. You will hear a snap as the hard disk cage locking tab slips into position.6 Reconnect power and IDE cables to the hard disk and connect the hard disk to the system:a Connect the IDE ribbon cable connector to the hard disk (or RAID card) IDE interface.b Connect the power supply to the hard disk.Warning: Protect the hardware components against damage from electrostatic discharge.Always wear a grounded wriststrap before you handle components. Always place thecomponents in a static-free container.Caution: It is vital that you connect the correct IDE ribbon cables to the correct harddisks. Connect the primary IDE ribbon cable to the primary hard disk. Connect the mirrorIDE ribbon cable to the mirror hard disk.Note: All connectors have a notch that allows you to align the connectors correctly.If you cannot push a connector in easily, do not force it. Examine the connector beforeattempting to install the cable to determine the correct orientation.
