Server Technology CX-16HFEK452 Sentry Switched Fail-Safe

The Sentry CX-16HFEK452 Fail-Safe^TM provides fail-over redundancy to single or dual-power supply servers and network devices. Exclusive to the Sentry Switched Fail-Safe is its ability to carry loads on the A circuit, B circuit or both and to remotely manage the outlets.

Similar, but unlike a common automatic transfer switch, the Sentry Switched Fail-Safe unit is unique in that it contains two (2) in-feeds and two (2) banks of eight (8) outlets each, for a total of 16 outlets across the two circuits.

The "A" in-feed routinely powers just the A1-8 outlets, and the "B" in-feed routinely powers just the B1-8 outlets. However, if the "A" in-feed goes down, the "B" in-feed powers all 16 outlets and the same if the "B" in-feed goes down, the "A" in-feed powers all the outlets.

This new "Fail-Safe" method has several advantages compared to a standard ATS because it does not prohibit load balancing between the two supplied circuits. A standard ATS contains two-in-feeds, but runs all outlets from just one source, with the secondary source only being used once an outage occurs on the capacity. This results in less heat, less resistance, and consequently less of a voltage drop compared to the same load existing on just one source. Only when an outage occurs on one of the two sources will the entire load be applied to a single source.

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 or EMCU-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 or EMCU-1-1 accessory.

Add a Second Tower
Connect an Expansion Cabinet PDU to any Switched Cabinet PDU to control 4 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 Enclosure
A horizontal enclosure that occupies 2U horizontal rackspace in the equipment cabinet. It typically mounts on the back of a 19 or 23 inch rack.

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 CW-16HF2/E 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 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).

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.
