Exclusive Network Management Tools ensure that your remote servers, internetworking devices and other equipment units operate in optimal conditions. Sentry™ XL  introduces exclusive new power measurement options to extend your network management capabilities and protect the investment in your internetworking equipment.

Key Features

• Expand network management capabilities with Load Sense and On Sense
• Protect your investment in internetworking devices with temperature thresholds
• Power load measured at each DC circuit
• Improve power planning and forecasting
• Add new equipment to existing power resources
• Maximize network uptime
• Monitor changes to the power state of internetworking devices
• Rectify conditions that cause power to your internetworking devices to be off

Real-Time Power Measurement
Using the Sentry XL, you can obtain three real-time measurement values for remote servers and internetworking devices that are critical to maintaining high service levels:

• Load Sense
• On Sense
• Temperature Sense

The Sentry XL permits threshold ranges to be defined for each measurement. When a measured value falls outside the defined threshold range, SNMP traps automatically report the exception condition.

Load Sense
Optimize your DC power facility investment. Sentry XL’s Load Sense measures the power load in amps at each DC power output block. Now you can measure precisely how much capacity remains on the new 60 or 100 Amp power feed that you just installed.
Using Load Sense you can now determine how much new equipment can be added to existing power resources. Because the manufacturer’s nameplate power rating specification on internetworking devices is generally inaccurate, power planning must be verified with a power measurement for each device. Sentry XL’s Load Sense remotely measures the amount of power being used by each device in a real-time manner, resulting in an accurate measurement for power planning.
Additionally, when a device’s load limits are exceeded, an SNMP trap is generated. Load Sense generates ongoing traps until the load returns to within a normal range.

On Sense
Sentry XL’s On Sense option verifies that there is voltage at the DC power outlet circuit. This positively confirms that power is "on" and available to your networking equipment units.  If power is not "on," an SNMP trap is generated whenever an error condition occurs on a power outlet circuit.

Temperature Sense
Protect your investment in expensive internetworking devices with Sentry XL’s Temperature Sense. Each Sentry XL is  fitted with one or more temperature probes that measure the ambient temperature in degrees centigrade inside the equipment rack.
For each equipment rack, the user can set high and low temperature thresholds. When these limits are exceeded, an SNMP trap is generated. Once the first trap is generated, a steady-state trap is generated periodically until the temperature returns to the normal range.
