Replacing the hard disk
This chapter describes how to replace the hard disks and hard disk cage assembly in the main unit.
The replacement procedures describe both the standard and RAID hard disk configurations.
For information on how to monitor and troubleshoot the hard disk in a standard or RAID
configuration, refer to
“System monitoring and troubleshooting” on page 223 .
This chapter contains the following primary topics:
• “Installing a RAID system” on page 263
• “Replacing a RAID configuration hard disk” on page 265
• “Removing a hard disk cage” on page 266
• “Installing a hard disk cage” on page 269
• “Replacing a hard disk in the hard disk cage” on page 273
• “Initializing the hard disk in a single-disk configuration” on page 281
• “Initializing the hard disk in a RAID configuration” on page 281
The hard disk is a core software and data storage component. For the BCM200 main unit, the hard
disk assembly installs at the rear of the main unit. For the BCM400 main unit, the hard disk
assembly installs in the advanced function tray.
Use the procedures described in this chapter under the following conditions:
• if you need to replace an existing hard disk in a standard configuration
• if you need to upgrade to a RAID configuration
• if you need to replace a hard disk in a RAID configuration
• if you need to replace a RAID card
Remember to take suitable precautions when working inside the BCM system. Maintain a clean
and static-safe site.
Danger: Electrical shock warning
Disconnect the power cord, telephone cables, and network cables before opening the BCM
main unit. Read and follow installation instructions carefully.
