System monitoring and troubleshooting

This chapter describes monitoring and troubleshooting options to determine the operational status of, or cause of malfunctions in, the BCM hardware.

This section describes the following troubleshooting topics and issues:

•“System status display LEDs” on page 216

•“Monitoring media bay module LEDs” on page 217

•“Monitoring the RAID LEDs” on page 219

•“RAID disk mirroring” on page 221

•“Monitoring or configuring disk mirror settings using Element Manager” on page 222

•“BCM system does not function” on page 226

•“Emergency telephone does not function” on page 226

•“ATA2 does not function” on page 227

Danger: Electrical shock warning.

Disconnect the power cord, telephone cables, and network cables before opening the main unit. Read and follow installation instructions carefully.

Warning: Protect the hardware components against damage from electrostatic discharge. Always wear a grounded wrist strap before you handle components. Always place the components in a static-free container.

Use Element Manager, or remote access interfaces, in conjunction with the faceplate LEDs to determine the operational state of the system hardware components.

Hardware problems are indicated by the following:

•The LEDs on the BCM base function tray, advanced function tray (RAID upgrade), or the media bay modules (MBMs) do not display normal operational status.

•The BCM system does not function at all.

•The emergency telephone does not function.

•The ATA2 does not function.
