Resilient and Redundant Design
A quick recovery and round-the-clock network is vital for service providers to establish a robust network. The Metro Switch 3000 Series provides comprehensive
features to make sure network is well operated. The IEEE 802.3ad Link Aggregation feature reduces network downtime by providing redundant paths and bandwidth
aggregation to critical connections, while IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) and IEEE 802.1s Multiple Spanning Tree Protocol (MSTP) allow immediate
recovery from failed connections by sending packets via the backup link. Furthermore, since the Metro Switch 3000 Series supports backup power system, the power is
supplied to the switch in case of an unexpected outage.
Intelligent Fan Control Algorithm for Power Saving
Fans play an important role in energy consumption since it's the key to heat dissipation. The Metro Switch 3000 features auto temperature detection and appropriate
fan speeds with the Intelligent Fan Control algorithm based on complex mathematics and physics formulas. When the ambient temperature is low, the switch would
decrease fan speed to prevent unnecessary power waste from excessive cooling.
Removable Fan Modules (MGS-3712, MGS-3712F, MES-3728 only)
Removable fan modules provide flexibility and high availability, and they solve the noise problem when the modules are approaching the end of their life cycle. When
necessary, customers can replace the fans with new ones by their own to save cost.
Optimized Design for Metropolitan Area Network, MAN (MGS-3712, MGS-3712F, MES-3728 only)
The Metro Switch 3000 Series offers high operating temperature tolerance, flexible AC/DC dual-input power source as well as protection against humidity and dust for
service providers to extend their networks. The Metro Switch 3000 Series adopts the "front access" design for technicians to easily wire and maintain outdoor cabinets.
The external alarm input/output block connects mechanical cabinet parts to the management network and offers better protection to the equipment.
Carrier Switches Supports DDMI (Digital Diagnostics Monitoring Interface) SFP (MGS-3712, MGS-3712F, MES-3728 only)
The enhanced digital interface allows real-time access to device operating parameters, and includes optional digital features such as soft control and monitoring of SFP
I/O signals. In addition, it fully incorporates the functionality needed to implement digital alarms and warnings.
The digital diagnostic monitoring interface enables users to have the capability of performing component monitoring, fault isolation and failure prediction tasks on
their transceiver-based applications.
DDMI Monitors:
•
Temperature
•
Supply voltage
• Transmitted bias current
• Transmitted power
• Received power
All features listed above include alarm and warning thresholds.
