Key Features


The Sentry 48DCWB-10-2X300-E0 Intelligent PDU and Remote Power Manager minimizes the impact of locked-up routers, servers and other network devices on business-critical networks. CLECs, ILECs, ISPs and enterprises use the Sentry 48DCWB-10-2X300-E0 to manage equipment in remote sites, co-location facilities and network operation centers. Sentry 48DCWB-10-2X300-E0 eliminates the need to dispatch a field service technician for manual intervention when devices lock-up. Using a Sentry 48DCWB-10-2X300-E0, the network operations center can quickly restart locked-up remote network servers to ensure that the network is fully operational around the clock.

Sentry 48 VDC provides immediate operational cost savings, including:

Eliminate the Need for a Separate Power Distribution Panel

The Sentry 48DCWB is an intelligent unit that combines the functions of a power distribution panel and remote power management unit into a 2U 19"rack-mounted enclosure. Each power output terminal connection is rated to switch 70-Amps and is protected by interchangeable TPC fuses allowing for the current rating to be adjusted onsite.

Measurement Features

Use either RS-232 or TCP/IP to monitor the status of key Measurement Values, SNMP or email alerts as well as Syslog to receive an alarm when a measurement value is out of a predefined threshold:

Input Feed/Outlet "On Sense" - Verifies power at each power input/outlet connection
Load Sense - Provides an accurate, real time measurement of the current draw, in amps, for each power outlet
Environmental Sensors - Supports two external probes to measure the temperature and humidity in an equipment cabinet to identify hot spots and humidity
