Installing a hard disk cage in a BCM200 main unit
Use this procedure to install the standard or RAID configuration hard disk cage into the BCM200
main unit.
To install a hard disk cage
1 Disconnect the BCM system from the AC power outlet.
2 Attach one end of the grounding strap to your wrist and the other end to a grounded metal
surface on the BCM main unit.
3 If accessible, remove the main unit top cover (see “Removing the main unit top cover” on page
252 ).
4 You can access the hard disk location from a panel at the rear of the main unit. Remove the
four hard disk access panel screws (see
Figure 124 ). Place the panel and screws in a safe
location.
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 disk
cage 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 the
chassis. 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 the
components in a static-free container.
Caution: It is vital that you connect the correct IDE ribbon cables to the correct hard
disks. Connect the primary IDE ribbon cable to the primary hard disk. Connect the mirror
IDE 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 before
attempting to install the cable to determine the correct orientation.
