Description:

Data Centers today most commonly standardize on dual-power corded servers and network gear as facilities managers continue to push for improved network availability. Regardless of the power input feeds, however, servers & network gear do occasionally lock-up and require a reboot via remote power control to bring them back to operational status. Data Centers aiming for 100% Uptime require a remote solution to reduce Mean Time to Repair (MTTR) to reduce downtime and improved productivity & efficiency.

The SentryTM Dual-Feed Power TowerTM (PTXL-HD16) is designed for servers and other devices with dual or redundant power supplies. It combines intelligent power distribution, remote power control, power monitoring and environmental monitoring into a single solution.

The PTXL provides Remote Power Management of each power receptacle, individually or as a selected group, via Web, SSH or SNMP management. Users can individually control each power outlet to remotely reboot network servers and internetworking devices. Or, power-off unused power outlets to prevent unauthorized power consumption on remote power circuit(s).

The exclusive Outlet Group Control feature of the power outlet-receptacles from two different power circuits allows a user to easily reboot a dual-power supply server or other device with a single command.

Input Current monitoring measures the aggregate load (in amps) on each power circuit. A digital display indicator on the Power Tower provides on-site verification of the load, and the remote user interface screen reports the same current measurement.

Key Features:

> Remote Management: Reboot locked-up servers and network gear via IP or out-of-band
> Power-up Sequencing of outlets prevents a power in-rush overload. User adjustable.
> Input Current Monitor: Power monitoring of the aggregate load on each power circuit (amps) remotely via the interface and locally on the enclosure.
> Authentication: Username/password required for network administrators & user accounts.
> Web GUI: Full conÿguration & control for managing and grouping outlets, user accounts and network settings
> Global Security Modem: Field replaceable modem can be added any time.
> Add a second tower: Connect a Power Tower Expansion Module (PTXM) to each PTXL to control up to 32 managed outlets (individual or groups).
> Outlet Grouping: Group individual outlets-between A and B Power circuits for control of dual-supply servers with a single command.
> Power Distribution: Dual 120V, 208-240V or 230V; 16A, 20A, 30A or 32A power input feeds
> RS-232 Control: Manage the Power Towers via an existing computer, KVM switch, terminal server or other serial device.
> Environmental Monitoring: Add temperature, humidity, water and intrusion monitoring with the EMCU-1-1
> SSHv2: Secure Shell for secure remote terminal
> SSLv3: Secure Sockets Layer-enabled HTTPS server.
> Active Directory with LDAPSv3: User authentication with LDAPv3

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. Environmental monitoring is applicable only with the additional purchase of the EMTH-1-1.

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). SNMP traps for temperature and environmental conditions require additional purchase of the EMTH -1-1 accessory.

Add a Second Tower - The PTXM

Connect the Power Tower Expansion Module (PTXM) to the PTXL to control two power input circuits and 32 managed outlets (individual or groups) - our exclusive strategy for managing dual power-supply servers.

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.

Optional Environment Monitoring

Add an Environmental Monitor Control Unit (item EMCU-1-1) to the PTXL to obtain real-time measurements of environmental conditions in the data center cabinet. EMCU-1-1 add-on requires no external power source and adds support for 2 Temperature & Humidity probes and monitoring for 4 external contact-closures and 1 water sensor.

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 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.

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.
