Overview
Data Centers today commonly standardize on dual-power corded network gear as facilities managers continue to push for improved network availability. Regardless of the power input feeds, however, network gear does occasionally lock-up and requires a remote reboot procedure to bring it back to operational status. Data Centers aiming for 100% uptime require a remote solution to reduce Mean Time to Repair (MTTR) to decrease downtime and increase improved productivity & efficiency.
The Sentry PT22 combines high-amperage Power Distribution with Remote Management for applications such routers and backbone equipment with high power draws that require a remote reboot. When a router or switch hangs or locks-up, the entire network lock-ups with it. However, the Sentry PT22 pdu enables network administrators to safely & efficiently reboot a hung-up router, switch or other network device to bring it back online quickly.
The PT22 is ideal for applications that require a remote reboot of high-amp 115 VAC or 230 VAC powered equipment. It includes convenient remote access features to allow management via LAN/WAN networks for secure Web, SNMP or SSH; dial-up connection; and RS-232 for local terminal.
Additionally, the PT22 supports Pass-Thru Console Port Access -- via the complimentary Sentry PT49 -- to integrate secure, in-band and/or out-of-band asynchronous communications for serial connections to remote devices' console ports. Link the Sentry PT49 (Pass-Thru Console Port Access) to the PT22 (Remote Power Management) and integrate these two features into one interface. A common application for the PT49 is to access & update the configuration able of a router, or eliminate multiple modem lines or the need for an expensive terminal server.
Features and Benefits
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 Cabinet PDU 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) a failing server by controlling individual power outlet receptacles to reboot any selected server or other device.
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.
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).
Add a Second Tower
Connect an Expansion Cabinet PDU to any Switched Cabinet PDU to control two power input circuits and manage outlets (individual or groups) under 1 IP address - our exclusive strategy for managing dual power-supply servers.
Horizontal 2U Rack Mount
A horizontal enclosure that occupies 2U Horizontal (19") of rack space in the equipment cabinet. It mounts on the back rails or in the cavity space of the cabinet.
Secure Access - SSH or SSL Protection
Secure Shell (SSH), 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.
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 ten-foot (10') cables provide real-time measurements in the data center cabinet.
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.
LDAP/LDAPS
The sentry family of products supports Lightweight Directory Access Protocol (LDAP) Version 3 including LDAPS (LDAP over TSL/SSL). This support enable authentication with LDAP servers; user accounts do not need to be individually created locally on each Sentry device.
This allows administrators to pre-define and configure (in each Sentry product, and in the LDAP server) a set of necessary LDAP groups, and access rights for each. User's access rights can then be assigned or revoked simply by making the user a member of one or more pre-defined Sentry LDAP groups. User account can be added, deleted, or changed in the LDAP server without any changes on individual Sentry products.
Sentry LDAP support has been tested in the following environments:
- Microsoft Active Directory (MSAD)
- Novell eDirectory (eDir)
- Open LDAP
Load Sense
Individual input current monitoring ("Load Sense") provides real-time power measurement of the load in amps on each power inlet, accessible via firmware interface.
RS-232
Serial control via any device with a bi-directional serial port, including a PC, laptop, KVM switch, Console Port Access switch, or terminal server.
20 or 30 Amp Power Input Support
20-amp power input support - IEC320/C20 power inlet receptacles supports any power cord with IEC320/C19 power connector (PTCORD-XX). 30-amp power input support provides hard-wired 10' cord and appropriate L5-30 or L6-30 plug type.
24-Character Outlet Receptacle 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.
