7 Overview Important safety information NOTE: The HP Intelligent Modular Power Distribution Unit (impdu) is intended for use only with information technology equipment (ITE) loads in racks or similar computer room applications. Extension bars ship with some kits. These extension bars are designed for use with Compaq/HP Modular Power Distribution Control Units and HP Uninterruptible Power Systems (UPSs). The extension bars can be used with other power sources, provided that the source includes branch circuit overcurrent protection not exceeding 20 A. WARNING: To reduce the risk of personal injury from electric shock, do not remove the cover. There are no field-serviceable or user-serviceable components inside. WARNING: A risk of personal injury from electric shock and hazardous energy levels exists. The installation of options and routine maintenance and service of this product must be performed by individuals who are knowledgeable about the procedures, precautions, and hazards associated with AC power products. Follow these safety precautions when connecting multiple hardware components to power sources. WARNING: To reduce the risk of personal injury or damage to the equipment: Plug the input power cord into a grounded (earthed) electrical outlet that is located near the equipment and is easily accessible. Be sure that the load products connected to the HP Intelligent Modular Power Distribution Unit (impdu) are adjusted for, or otherwise capable of operation from the same line voltage supplying the impdu. Failure to verify the voltage can lead to severe equipment damage. Do not overload the impdu. The total input current rating of all equipment connected to each output cannot exceed the total output rating marked on the impdu. WARNING: To reduce the risk of personal injury from high-leakage current, verify earth connection before connecting the power supply. The summation of input power for multiple pieces of information technology equipment through the use of power products can result in high-leakage currents. If the total system leakage current for a system of components exceeds 3.5 ma: The use of a detachable input power cord is prohibited. The input power cord must be securely attached, and it should be connected to the AC mains by hardwiring or through the use of a non-residential, industrial-style plug that maintains positive earth connection. If the total system leakage current through the ground conductor exceeds 5% of the input current per line under normal operating conditions, the system loads should be divided among multiple power connections. Overview 7

8 Introduction Features The HP Intelligent Modular Power Distribution Unit (impdu) has an industry first feature of power topology automatic discovery. The impdu automatically discovers HP ProLiant servers* powered by the impdu, enabling data center managers to know with certainty that installed equipment is powered as designed. Unexpected server shutdowns can occur due to human error as routine maintenance tasks are performed, and are often the first indication that a server is not powered as documented. The ability to automatically determine the power topology increases reliability and allows data center managers to maximize the rack, power, and thermal resources in the data center. The impdu power topology discovery also enables HP Thermal Logic solutions, such as Insight Control Power Manager advanced group power capping for ProLiant DL/ML and Integrity servers with ilo 2 management processors and optional upgrade licenses, to reach their full potential by reducing human error when assigning servers to a power capping group. The impdu enables you to monitor, manage, and control power environments. Multiple devices can monitor the impdu over the network connection. The input voltage of a single phase impdu is 200 to 240 VAC. The input voltage of a three phase impdu is 200 to 240 VAC or 380 to 415 VAC, depending on the model. For configuration and status monitoring, the impdu includes: HP Intelligent PDU web interface (on page 32) A graphical interface that is accessed with a web browser HP Intelligent PDU Service Menu (on page 59) A text-based menu that is accessed through telnet or a terminal emulation session To benefit from the latest product enhancements, update to the latest versions of firmware and software. NOTE: To download the latest versions of firmware and software, see the HP website ( * Power topology automatic discovery requires HP ProLiant servers with ilo 2 v2.0 or newer firmware, combined with the intelligent extension bar, discovery data power cords, and HP ProLiant 94% efficiency common slot power supplies. impdu features include: Power topology automatic discovery for HP ProLiant servers with ilo 2 v2.0 or newer firmware when combined with the intelligent extension bar, discovery data power cords, and HP ProLiant 94% efficiency common slot power supplies.

34 Browser security alert Secure browsing requires the use of SSL. SSL is a protocol layer that lies between HTTP and TCP that provides secure communication between a server and a client and is designed to provide privacy and message integrity. SSL is commonly used in web-based transactions to authenticate the web server, which indisputably identifies the server to the browser. SSL also provides an encrypted channel of communication between the server and the browser. The encrypted channel ensures integrity of the data between the web server and the browser, so that data can neither be viewed nor modified while in transit. The impdu uses a system generated certificate and unique key. An integral part of SSL is a security certificate, which identifies the impdu. If your browser displays a security alert when browsing to the impdu, it can be for one of several reasons: The certificate is untrusted, meaning it was signed by a certifying authority that is unknown to your browser. The certificate has expired or is not yet valid. This condition can occur if you issue your own certificate and it has expired. The Common Name (name or IP address) on the certificate does not match the name or IP address of the site in the browser address field. For more information about security considerations, see "Security considerations overview (on page 85)." For more information about certificates and keys, see "Installing a digital certificate and encryption key for SSL (on page 85)."

82 Systems Insight Manager integration Systems Insight Manager overview Use HP Systems Insight Manager to: Discover impdus. As part of the discovery process, HP SIM can detect an installed impdu. The web interface for the discovered impdu can be launched from the HP SIM All Systems page. Receive SNMP traps from the impdu. The impdu can send event-based traps to HP SIM that include a URL in the trap. This functionality enables administrators to easily launch the web interface of the impdu in context. For example, if the impdu detects an alarm condition, the impdu can send a trap to HP SIM with an attached hyperlink that routes users directly to the Overview screen for the attached impdu. Conveniently launch the impdu web interface from within HP SIM. o All Systems page All discovered impdus appear on the All Systems page. Click the link in the System Name column to launch a browser session. o Event-based trap A URL is included in each trap to link directly from HP SIM to the Overview screen for the specific device for which the trap was sent. Discovering the impdu HP SIM automatically detects impdus as part of the device discovery process. If detected, a hyperlink is included on the HP SIM All Systems page for the impdu. The impdu should be installed and running before attempting discovery through HP SIM. If the defaults are not used, a new entry can be made to the additionalwsdisc.props file, located in the CONFIG directory in the HP SIM install directory, to allow HP SIM to correctly discover and identify the impdu. For more information on editing the additionalwsdisc.props file, see the additionalwsdisc.txt file located in the same directory. Systems Insight Manager integration 82

83 Example: ADDITIONALWSDISC.PROPS file with impdu entry # # Additional Web Server Discovery Properties # # # NOTE: See "additionalwsdisc_readme.txt" for a description of entries in # this file and how to add or remove additional web server ports used for # discovery and identification. # # # # The following are actual web server ports enabled by default. # To remove them from the discovery process, comment out the line with a '#' # or remove it. You will need to restart the HP SIM service for # the changes to take effect. In addition you will need to run the Device # Identification task to find any new ports that were defined. # =Director Agent,,true,false,,http 3201=Compaq TaskSmart,,true,false,,https 8008=Default Home Page,,true,false,,http 1311=Server Administrator,,true,false,,https 1234=HP impdu,,true,false,,https The last entry allows HP SIM to detect the impdu running on port 1234 and using HTTPS (Secure Socket Layer protocol). HP SIM services must be restarted to apply the change. Configuring HP SIM to receive traps Before HP SIM can receive traps, the correct MIB file (cpqpower.mib) must be compiled into HP SIM. To download the HP Power MIB, visit the HP website ( To register the MIB: 1. Copy the MIB to the HP\Systems Insight Manager\mibs folder. 2. From the HP\Systems Insight Manager\mibs folder, run mcompile cpqpower.mib from the command line to compile the new MIB. A new file named cpqpower.cfg is created. 3. Register the new MIB by entering mxmib -a cpqpower.cfg from the HP\Systems Insight Manager\mibs command line. 4. Enter HP\Systems Insight Manager\mibs>mxmib at the command line and verify that the new MIB is listed. Systems Insight Manager integration 83

84 NOTE: For more information on uploading and registering a MIB in HP SIM, refer to the HP Systems Insight Manager Technical Reference Guide located on the HP Management CD. Configuring the impdu to send traps to HP SIM On the impdu web interface: 1. Click the Setup tab. 2. Click the Network Management menu. 3. Add the HP SIM server as an SNMP trap recipient on the Trap Receivers tab (on page 51). 4. Configure the impdu to send alert notifications to HP SIM on the Event Notifications tab (on page 54).

85 Security considerations Security considerations overview The impdu implements strict security for two important reasons: The impdu manages devices that have the potential to perform operations that are sensitive and destructive. The impdu has browser accessibility. To better ensure the security of the impdu and the devices it manages, consider the following topics in accordance with your organization's security policies and the environment in which the impdu will operate. Remote access to the impdu requires a user account. Logging in requires the use of a user name and password, which should be kept properly secured. Each account can be given different access levels, providing different capabilities. Ensure that the appropriate access level is granted to users. The web interface is installed behind the firewall. Browsing to the impdu can be done using SSL, which encrypts the data between the browser and impdu. The impdu is supported by a 128-bit encryption level. SSL also provides authentication of the impdu by means of its digital certificate. Securely importing this certificate must be done to ensure the identification of the impdu. Use a custom SSL certificate that is certified by a third-party SSL authority. When a browser logs in to the web interface, other browsers on the system also log in. Consider limiting the time that a browser can be logged in to an account with administrative privileges. Use non-standard ports for the impdu web interface. Disable telnet if remote configuration is not used. Disable the web interface if the web interface is not preferred. Installing a digital certificate and encryption key for SSL The SSL protocol provides for encryption, server and client authentication, and message authentication. To create your own certificate and key for SSL: Linux Many Linux distributions come with pre-compiled OpenSSL packages. Windows A Windows version of OpenSSL can be found at the following website: ( Instructions for creating a self-signed certificate using OpenSSL can be found at the following website: Security considerations 85

86 ( To create your own 512- or 1024-bit SSL certificate and key, you can use the command in the following example: openssl req -x509 -nodes -days 365 -newkey rsa:512 -md5 -keyout mycert.pem -out mycert.pem -text The mycert.pem file includes both a certificate and an encrypted key. NOTE: To prevent a domain mismatch, make sure to enter the host name or IP address of the impdu in the Common Name field when creating a certificate. Since your certificate includes a private key, a pink error heading at the top of your browser. If this occurs, view and install the certificate into your trusted root folder. To copy the certificate to the impdu web server: 1. Log in to the impdu web interface. 2. Click the Setup tab. 3. Click the Network Management menu. 4. Click the Remote Access tab 5. Make sure that web access is enabled and that the HTTPS port is 443 (default) or your preferred HTTPS port number. 6. Paste the certificate (contents of the mycert.pem file) in the SSL Key field. The key must be in the following format: -----BEGIN RSA PRIVATE KEY key contents END RSA PRIVATE KEY----- Certificate: Data: BEGIN CERTIFICATE certificate contents END CERTIFICATE Click Save Settings. 8. Click OK on the reboot prompt. 9. Allow the impdu to reboot. 10. Change the URL used to access the web interface to HTTPS. Security considerations 86

87 Optional power monitoring using SNMP SNMP monitoring The impdu status, events, and traps can be monitored using third-party SNMP managers. SNMP monitoring supports the RFC-1628 MIB and the HP Power MIB (CPQPOWER.MIB). To configure SNMP monitoring: 1. Using the SNMP Managers tab (on page 52), configure the third-party SNMP manager to monitor the impdu. 2. Using the third-party SNMP manager software, configure the impdu information to be monitored by the SNMP manager. The HP Power MIB (CPQPOWER.MIB) can be downloaded from the HP website ( Optional power monitoring using SNMP 87
