The Sentry 4805-XLS-16B Intelligent PDU and Remote Power Manager minimizes the impact of locked-up routers, servers and other network devices on business-critical networks. CLECs, ILECs, ISPs and enterprises use the Sentry 4805-XLS-16B to manage equipment in remote sites, co-location facilities and network operation centers. Sentry 4805-XLS-16B eliminates the need to dispatch a field service technician for manual intervention when devices lock-up. Using a Sentry 4805-XLS-16B, the network operations center can quickly restart locked-up remote network servers to ensure that the network is fully operational around the clock.

Sentry 48 VDC PDUs provide immediate operational cost savings, including:

Reduced field service visits
Improved problem/solution response time
Improved network availability
Improved facility security

Eliminate the Need for a Separate Power Distribution Panel

The Sentry 4805-XLS-16B is an intelligent unit that combines the functions of a power distribution panel and remote power management unit into a 2U 19"rack-mounted enclosure.
Sixteen output terminal connections (eight per input) are rated to switch 10 amps. Each outlet is protected by interchangeable GMT fuses allowing for the current rating to be adjusted onsite.

Measurement Features

Use RS-232 and/or TCP/IP to monitor the status of key measurement values. Receive SNMP or email alerts as well as Syslog when a measurement value is out of a predefined threshold.
Input Feed/Outlet "On Sense" - Verifies power at each power input/outlet connection.

Load Sense - Provides an accurate, real time measurement of the current draw, in amps, for each power outlet.
Environmental Sensors - Supports two external probes that each measure temperature and humidity.

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).

Rack Mount Enclosure

"Horizontal" rack-mount enclosures are 17" wide and include standard mounting brackets for 19" cabinet rails. 23" brackets also available.

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.

Firmware Flash Upgradeable LDAP/LDAPS

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.

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.
