Server Tech Sentry Smart PDU, 0U, Expansion Module (CL-24V2-C20M)

Please note, the ServerTech CL-24V2-C20M PDU has been discontinued. For replacement options, please contact your Server Racks Online sales representative.

The Server Technology CL-24V2-C20M is a 0U, 24 outlet, 20A, 208-240V, IEC 60320/C20 Power Inlet, Sentry Smart Rack PDU Expansion Module.  The Smart Cabinet Power Distribution Units (CDU) provide reliable power distribution combined with local and remote power monitoring and environmental monitoring via IP. Use the network interface to view power, temperature and humidity levels via Web browser, or receive SNMP based alarms and email alerts when conditions exceed defined thresholds.

The Smart CDU family has the capability to daisy chain units together. The Expansion CDU Module gives the ability to use one IP address across different power circuits.

Server Tech CL-24V2-C20M Features:

  • Mid and High Density: Single-power input feed; 24 outlets per enclosure
  • High Power Distribution: 100-120V & 208-240V power options; 16, 20, 30, or 32-Amp power input feed options.
  • Input Current Monitor: Precisely measure the aggregate current draw (in amps) on each branch circuit. On-site verification of the input current with the LED digital display.  Remote verification via web browser or serial screen.
  • IP Access & Security: Web interface, SSL, SSH, Telnet, SNMP, FTP, SNTP, Syslog, LDAP, LDAPS, TACACS and RS-232 access
  • Alerts: Provide automated SNMP-based alarms or email alerts for power and environmental conditions
  • Environmental Monitoring: Each Smart CDU supports two external temperature & humidity probes and reports conditions through the user interface without the need for additional IP addresses
  • Add an Expansion Module: Daisy chain the Smart CDU Expansion Module (CS/CL) for power monitoring of separate power circuits from a single IP address

Notes:

  • This unit is an Expansion Module.
  • Please note that the depth of these enclosures are 3.00" deep at the placement for the fuse retractors

Server Tech Smart PDU Additional Features:

  • Fuse Retractors for Branch Circuit Protection- These new tool-less retractors pull out for easy access and replacement of fuses. The Sentry CDU Family meets the UL 60950-1 requirement for branch circuit protection. Attention! The Sentry CDU products meet the above criteria by providing overcurrent protection with UL-listed Bussman SC fuses for each branch circuit.

  • Input Current Monitoring- Exclusive True RMS current monitoring is critical to preventing overloads in high-density computing environments. LED digital displays on the CDU enclosure report the input current of each phase or branch circuit for simple load balancing.

  • Temperature and Humidity- The Smart CDU supports two external 10’ (3m) probes. Each of these probes measure both temperature and humidity. Receive SNMP-based alerts or email notifications when conditions exceed defined thresholds.

  • Linking for Smart CDU (Expansion Modules)- The Smart CDU family now has the capability to daisy chain units together. The Expansion Module provides the ability to link two power circuits under one IP address.

  • Remote Power Monitoring- Monitor input power via IP or serial interface.

  • HTTP/HTTPs Web Configuration & Control- Use the Sentry Web interface to configure each unit's network settings. SNMP traps for environmental & power thresholds and firmware updates. Also use the Web interface to 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 such as input power, temperature and humidity. 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, and closed contacts (cabinet doors open/close).

  • Add a Second Tower- Connect an Expansion Cabinet PDU to this Smart Cabinet PDU to control two power input circuits and monitor power in the Data Center cabinet (individual or groups) under 1 IP address - our exclusive strategy for managing dual power-supply servers.

  • Zero U Enclosure- A vertical enclosure that occupies Zero Vertical U 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 Probe Support- 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

  • 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.
