• Fault management for viewing BCM50 alarms. You can set which alarms are displayed in
the Element Manager alarm browser and which alarms trigger an SNMP trap.
• Log management for off-box transfer of logs, including component logs and administrator
logs such as alarm log, security log, configuration change log, and system log.
• Software management tools for software updates (for example, for corrective software)
and software upgrades.
• Backup and restore. You can schedule configuration backups or application backups. An
application backup includes data generated through the day-to-day use of the on-box
applications as well as the configuration data. A scheduled backup provides the ability to
routinely perform a backup, which can be kept on the BCM50 hard drive or transferred to
an off-box destination such as network folder, FTP server, or locally attached USB storage
device.
For backup and restore, software management, and log management, a flexible set of source and
destinations is supported along with protocols to access them. For example, you can save backups
from the BCM50 to either the USB port, the Element Manager client PC (on-demand only), a
shared drive available on the network, or a remote FTP server.
Software updates
To ensure that BCM50 maintenance costs are low, even in an environment of security and
corrective content updates, the BCM50 handles software updates as follows:
• You can download software updates to the BCM50, either on-demand or according to a
schedule, from a USB port, a shared network drive, a remote FTP server, or a client PC.
• Update software is automatically checked against the BCM50 software history and
validated before it is transferred.
• You can schedule the application of the software update separately. For example, you can
schedule a download for Tuesday night, but the application can be scheduled for Friday at
2 a.m.
• You can program multiple software-update packages to be applied at the same time.
• One software-update package may include updates for multiple software components.
While many software updates do not require a system reboot, some software components
require a reboot for the update to take effect. No more than one system reboot is required
if one or more of the software components being updated by the software-update package
require a reboot.
• Software upgrades are handled in the same way and use the same tool as software updates.
• You can set up the entire software-update process for hands-off operation if the software
content can either be downloaded remotely or sent out and installed from the USB port.
Keycodes
The BCM keycode structure has been redesigned with these capabilities:
• One keycode validates all feature entitlements, which simplifies installation.
• You can apply keycodes in a number of ways:
— through Element Manager
