Sentry 4820 Power Distribution & IP Power Reboot Unit minimizes the impact of locked-up routers, DSLAMs, ATM switches and other internetworking devices on business-critical networks. CLECs, ILECs and ISPs use the Sentry 4820 to manage equipment in remote sites, co-location facilities and Telco central offices. The Sentry 4820 eliminates the need to dispatch a field service technician for manual intervention when devices lock-up. Using a Sentry 4820, the network operations center can quickly restart locked-up remote internetworking deviceswith an IP power reboot to ensure that the network is fully operational around the clock.
24-character Outlet Receptacles Names 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.
Firmware Flash Upgradeable 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.
HTTP/HTTPs Web Configuration & Control 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.
Integrated Temp/Humidity Probes 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 six-foot (6′) cables provide real-time measurements in the data center cabinet.
LDAP 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
Load Sense Individual input current monitoring (“Load Sense”) provides real-time power measurement of the load in amps on each power outlet, accessible via firmware interface.
Overcurrent Alarm Audible (local) alarm sounds when defined maximum current load (amps) is exceeded.
Rack-Mount Enclosure “Horizontal” rack-mount enclosures are 17″ wide and include standard mounting brackets for 19″ cabinet rails. 23″ brackets also available.
Remote Power Control 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.
RS-232 Control 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 Access – SSH or SSL Protection 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.
SNMP Management & Event Notification 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).
