See also “Replacing a hard disk in the hard disk cage” onpage 267.To remove a hard disk cage from a BCM400 main unit1 Shut down the system (see “Performing a system shutdown” on page 233).2 Disconnect the BCM system from the AC power source.3 Attach one end of the grounding strap to your wrist and the other end to a grounded metalsurface on the BCM400 main unit.4 Partially remove the BCM400 advanced function tray (see “To remove the advanced functiontray” on page 243). Do not to pinch or stretch any cables when sliding the advanced functiontray partially out of the main unit.5 Locate the hard disk or RAID cage in the advanced function tray.6 Disconnect the hard disk cables from the system:a Disconnect the power supply connector from the hard disk.b Disconnect the IDE connector from the hard disk (or RAID card).7 Carefully remove the advanced function tray completely from the main unit. Do not pinch orstretch any cables when sliding the advanced function tray away from the main unit.8 Remove the transportation hard disk cage restraint screw and keep it in a safe place.9 Place the advanced function tray on a flat, static-free surface.10 Place your fingers under the tab located at the bottom rear of the hard disk cage. Firmly lift thetab. At the same time, slide the hard disk cage in the direction shown in Figure 125 until theunit detaches from the mounting points on the advanced function tray.Warning: Protect the hardware components against damage from electrostatic discharge.Always wear a grounded wriststrap before you handle components.
