Sentry™ 4805/35 XL Remote Power Manager is a switched PDU that minimizes the impact of locked-up e-mail servers and other internet-working devices on business-critical networks. CLECs, ILECs and ISPs and enterprises use the Sentry 4805/35 to manage equipment in remote sites, co-location facilities and network operations centers.
The 4805/35-XL is an intelligent switched PDU that combines the functions of a power distribution panel and remote power management unit into a compact 2U 19” rack mounted enclosure. It eliminates the need to have a field service technician go out for manual intervention when devices lock-up. Using a Sentry 4805/35, the network operations center can quickly restart locked-up remote network servers to ensure that the network is fully operational around the clock.
This unit combines low and high Amp power outlet circuits for multiple devices and features two 100-amp power input feeds. Each power output terminal connection is protected by a GMT or TPC fuse. (The GMT fuse capacity can range from 1/2 to 10 Amps, the TPC fuse from 3 to 70-Amps.) A key application for the 4805/35-XL is power distribution & remote management for a cabinet of both -48 VDC-powered servers and high-amp routers.
It also has the ability to monitor the environment conditions in the data center equipment cabinet by measuring the ambient temperature and humidity. This prevents damages occurring from hot spots and high humidity. The 4805/35 includes Load Sense and On Sense features and support for SNMP traps. These can verify voltage and amperage amounts at each power inlet or outlet connection.
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).
