As enterprises and servers increase the amount of servers and network gear in remote locations, the ability to hands-on manage each device becomes increasingly complex. The amount of equipment, the distance between each field site and the ongoing constraint of the number of available personnel make this challenge even more difficult. The number one priority in managing each device is to ensure that each element is operational-that is, up and running.

Two common examples where managing remote equipment are critical to their organization's business are: 1) Remote branch offices with IT & network equipment placed at each location, and 2) Wi Fi networks that encompass many pieces of individual equipment at numerous locations. In either case, the amount of equipment on the network(s) far outnumbers the amount of IT/equipment maintenance personnel.

Their first priority is to keep the network(s) up and running. In order to do so, they require solutions that allow them to be able to remotely restore locked-up or failing equipment, whether it is a router, server or PC at a remote branch office, or an access point or router at one its Wi Fi Hot spots.

Remote Power Management of the IPM-2 individual receptacles allows a network manager to power off, power on and reboot network devices from any location via secure web interface, SSH, or out of band (dial-up) session. Now the network operations center can eliminate dispatching a field service person for manual intervention. Using a Sentry IPM-2 they can quickly restart locked-up remote servers & internetworking devices to ensure that the network is fully operational around the clock.

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).

1U Enclosure

A horizontal enclosure that occupies 1U horizontal rack space 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.

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.

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

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.

16 Amp Power Input Support

16-amp power input support - IEC320/C20 power inlet receptacles supports any power cord with IEC320/C19 power connector.

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.
