Basic Tab 39
The firmware and mail/log storage shows the percent of space used on each partition. The Barracuda
Spam Firewall e-mails a system alert when utilization approaches 90% on either of these partitions.
Contact Barracuda Networks technical support if a partition reaches this threshold.
Subscription Status
This section identifies if the following subscriptions are current or expired:
• Energize update
• Instant Replacement (optional service)
If one of these subscriptions has expired, contact your Barracuda Networks sales representative to re-
activate your subscription.
Hourly and Daily Mail Statistics
Shows the number of messages blocked, quarantined, and allowed for the last 25 days and 24 hours.
Understanding the Indicator Lights
The Barracuda Spam Firewall has five indicator lights on the front panel that blink when the system
processes e-mail.
System Load Estimate of the CPU and disk load on the system.
100% system load is not unusual, especially when the incoming queue is
large. However, 100% load for long periods of time could indicate an internal
system issue, especially if the incoming queue continues to grow.
Redundancy Status of the RAID system.
Note: The redundancy statistics do not appear for the 200 and 300 models.
Firmware Storage Amount of disk storage used for various system components.
Mail/Log Storage Amount of disk storage used for messages and log store.
