Sentry™ 4870 Remote Power Manager & Power Distribution Unit minimizes the impact of locked-up routers, DSLAMs, ATM switches and other high amperage equipment units on service provider's networks. CLECs, ILECs and ISPs use the Sentry 4870 to manage equipment in remote sites, co-location facilities and Telco central offices. The Sentry 4870 eliminates the need to dispatch a field service technician for manual intervention when devices lock-up. Using a Sentry 4870, the network operations center can quickly restart locked-up remote internetworking devices to ensure that the network maintains maximum uptime.

Use the firmware interface (Web or serial) to edit individual outlet receptacles. Identify each receptacle with the device's serial number, ip address, asset allocation #, department or any other method to individually name outlets.

Access new firmware updates via FTP for new firmware features and code releases. An update to the firmware does not affect the status of the power outlets.

Use the Sentry Web interface to configure each unit, including network settings, outlet naming & grouping, SNMP traps for environmental & power thresholds and firmware updates. Also use the Web interface to control individual or group outlets and monitor key values, including amperage load(s), temperature/humidity and other environmental conditions. SSL security provides a secure HTTPs connection.

Two (2) RJ-style connectors located on the face panel of the PDU's enclosure provide support for two (2) Integrated Temperature & Humidity Probes with ten-foot (10') cables provide real-time measurements in the data center cabinet.

LDAP (Lightweight Directory Access Protocol) is a software protocol for enabling anyone to locate organizations, individuals, and other resources such as files and devices in a network, whether on the public Internet or on a corporate intranet. Sentry firmware code 5.3b and newer  includes support for LDAP v3 and is configurable to operate with any Directory Service. It has been tested with these Directory Services: Microsoft’s Active Directory, Novell’s eDirectory, OpenLDAP

Individual input current monitoring ("Load Sense") provides real-time power measurement of the load in amps on each power outlet, accessible via firmware interface.

"Horizontal" rack-mount enclosures are 17" wide and include standard mounting brackets for 19" cabinet rails.  23" brackets also available.

Individual or group outlet remote power control to cycle power and reboot any selected server(s) or other network device(s).  Use TCP/IP (HTTP, HTTPS, SSH, Telnet, SNMP) or RS-232 to communicate with each Sentry and rectify locked-up network devices. Assign outlets to a group for control of dual-power supply servers and other gear with a single command.  Create an unlimited number of groups with any combination of outlets associated to each group. Reduce Mean Time to Repair (MTTR) of a failing server by controlling individual power outlet receptacles to reboot any selected server or other device.

Serial control via any device with a bi-directional serial port, including a PC, laptop, KVM switch, Console Port Access switch, or terminal server.

Secure Shell (SSH), sometimes known as Secure Socket Shell, is a Unix-based command interface and protocol for securely getting access to a remote device.  Sentry supports SSHv2. Secure Sockets Layer (SSL) is a commonly-used protocol for managing the security of a message transmission on the Internet. SSL is an integral part of most Web browsers (clients) and Web servers.  Sentry supports SSLv3/TLSv1.

The Sentry family of products supports the Simple Network Management Protocol (SNMP). This allows network management systems to use SNMP requests to retrieve information and control power for the individual outlets. The Sentry includes an SNMP v1 agent supporting standard MIB I and MIB II objects. A private enterprise MIB extension (Sentry3 MIB) is also supported to provide remote power control. SNMP traps can be generated for various events, including Input Current Load Thresholds (min & max), Temperature Thresholds (min & max), Humidity Thresholds (min & max), water indication, closed contacts (cabinet doors open/close), as well as notification of any time an outlet status is changed (on/off).
