Alarm Configuration

7.2. The Over Temperature Alarms

The Over Temperature Alarms are designed to inform you when the temperature level inside your equipment rack reaches or exceeds certain user-defined levels. There are two separate Over Temperature Alarms; the Initial Threshold alarm and the Critical Threshold Alarm.

Typically, the Initial Threshold alarm is used to notify you when the temperature within your equipment rack reaches a point where you might want to investigate it, whereas the Critical Threshold alarm is used to notify you when the temperature approaches a level that may harm equipment or inhibit performance. The trigger for the Initial Threshold alarm is generally set lower than the Critical Threshold alarm.

If the user-defined trigger levels for temperature are exceeded, the MPC can automatically shut off power to non-essential devices ("Load Shedding") in order to reduce the amount of temperature that is being generated within the rack. In addition, the Load Shedding feature can also be used to switch On additional components, such as fans or cooling systems in order to dissipate the excess heat. After Load Shedding has taken place, the Load Shedding Recovery feature can be used to return plugs to their previous state after the temperature drops to an acceptable level.

Notes:

In order for the MPC to provide alarm notification via Email, communication parameters must first be defined as described in Section 5.9.11.

In order for the MPC to provide alarm notification via Syslog Message, Syslog parameters must first be defined and Syslog Messages must be enabled as described in Section 5.9.2 and Section 11.

In order for the MPC to provide alarm notification via SNMP Trap, SNMP parameters must first be defined, and SNMP Traps must be enabled as described in Section 5.9.7 and Section 12.

When additional, optional remote MPC units have been connected to the AUX Ports on your local MPC unit, Over Temperature alarms can also be separately defined for each individual Local/AUX unit.

To configure the Over Temperature Alarms, access the MPC command mode using a password that permits Administrator Level commands, and then proceed as follows:

Text Interface: Type /AC and then press [Enter] to display the Alarm Configuration Menu. From the Alarm Configuration Menu, either type 3 and press [Enter] to access the Over Temperature (Initial Threshold) Alarm, or type 4 and press [Enter] to access the Over Temperature (Critical Threshold) Alarm.

Web Browser Interface: Click the "Alarm Configuration" link, located on the left hand side of the screen to display the Alarm Configuration Menu. From the Alarm Configuration Menu, click on either the "Over Temperature (Initial Threshold)" link or the "Over Temperature (Critical Threshold)" link to access the desired menu.

Note that both the Initial Threshold menus and Critical Threshold menus offer essentially the same set of parameters, but the parameters defined for each alarm are separate and unique. Therefore, parameters defined for the Critical Threshold Alarm will not be applied to the Initial Threshold Alarm and vice versa.

The Western Telematic MPC series is renowned for its robust and versatile remote power management solutions. Among its offerings, the MPC-20VS16-3, MPC-20VD16-3, MPC-20VD20-2, MPC-20VS20-1, and MPC-20VS20-2 stand out as exceptional products tailored to meet the demands of modern telecommunications and data center environments.

One of the key features across this series is the ability to monitor and control up to 20 power outlets, which allows for efficient resource management and reduces downtime. Each model in the series accommodates various configurations, including both switched and non-switched outlets. This flexibility makes it easier for operators to manage power distribution according to their specific needs.

The integration of real-time monitoring capabilities is another highlight of the MPC series. Users can track power consumption, voltage, and current for each outlet, enabling better decision-making to optimize energy usage. This feature contributes significantly to the overall efficiency of operations, ensuring that resources are utilized effectively.

Communication is seamless with the Western Telematic MPC series, as these models are equipped with multiple network connectivity options. They support both SNMP (Simple Network Management Protocol) and Telnet, facilitating easy integration with existing network management systems. Additionally, the devices can send alerts and notifications via email or SMS, keeping operators informed about any changes in power status or potential issues.

The MPC models are designed with redundancy and reliability in mind. They come equipped with advanced surge protection, ensuring sensitive equipment remains safe from power spikes. The rugged construction of the units ensures they can withstand the rigors of data center environments, with an emphasis on heat dissipation and airflow management.

Security features are also a priority. The MPC series includes user authentication and access control to prevent unauthorized users from manipulating power settings. The ability to set user permissions ensures that only designated personnel can operate sensitive components, enhancing operational security.

Energy efficiency is a guiding principle in the design of the MPC series. By providing tools for monitoring and controlling power usage, these devices contribute to a reduction in energy costs, aligning with sustainability goals sought by modern enterprises.

In conclusion, the Western Telematic MPC-20VS16-3, MPC-20VD16-3, MPC-20VD20-2, MPC-20VS20-1, and MPC-20VS20-2 are exemplary models in the field of remote power management. With features such as comprehensive outlet control, real-time monitoring, robust communication options, security protocols, and a focus on energy efficiency, these units are engineered to meet the rigorous demands of the telecommunications and data center sectors. By implementing these advanced technologies, operators can enhance their operational capabilities while also contributing to long-term sustainability.
