| Lights-Out management provides virtual on-site management capabilities. Instead of calling the remote site to have another person issue keyboard commands and listening to the other person describe the response from the server, you can view server operations and manage the server directly, as illustrated in Figure 17-1. Figure 17-1. How Lights-Out technology works. 
HP Lights-Out technology includes two main solutions: RILOE II and iLO. RILOE II is a PCI card that provides full control of hardware and operating systems for a server through a client browser. RILOE II has a dedicated processor, memory, network interface card (NIC), and an AC adapter that makes it completely independent of the host server operating system and hardware. It is the successor of the RILOE card. The major difference is the faster processor on the RILOE II card (200MHz PPC against 66MHz i960). iLO is an intelligent processor and firmware integrated on selected ProLiant servers. This technology also supports collection of ProLiant BL p-Class rack information. Both products offer many of the same features with a few exceptions, which are noted in this chapter. Both types are configured through the ROM-Based Setup Utility (RBSU), which is accessed by pressing F8 at server startup. 17.1.1 Key Features of HP Lights-Out Technologies The key features of HP Lights-Out management options include the following: Autoconfiguration of IP address Provides automatic network configuration, which includes a default name and Dynamic Host Configuration Protocol (DHCP) client. Browser accessibility Allows access to the remote host server regardless of the state of the host server or operating system. Dedicated LAN network connectivity Provides a dedicated network connection that is capable of selecting speeds between 10 and 100Mb/s. Microsoft Emergency Management Service (EMS) console Provides a text-based screen to access the host server. A feature of Microsoft Windows Server 2003, EMS enables you to display running processes, change process priority, and halt processes. Without a Lights-Out device, you need a physical connection to the server using a serial cable. However, with Lights-Out devices, you can use EMS through a Web browser. Integrated Management Log (IML) Allows access to the IML of a host server even when the server is not operational. Integration with HP Insight Manager Provides support for Simple Network Management Protocol (SNMP) trap delivery, SNMP management, a management processor, and grouping of Lights-Out devices. In addition, an application launch task can be configured to start the Group Administration Utility on RILOE II devices. Insight Manager also provides a hyperlink on the server device page to launch and connect to iLO and RILOE II devices. Power cycle (reset) Enables you to initiate a cold reset from the remote console to bring the host server back online when it is not responding. This type of restart does not shut down the server operating system gracefully, but proves useful in situations when the operating system is unresponsive. Remote firmware update Enables you to update the firmware of the Lights-Out device. SNMP alerts Allows access to server alerts such as SNMP alerts and unauthorized access alerts. Single-mouse cursor mode Enables single-mouse cursor mode in the remote console. To enable the single-mouse cursor, the administrator must install the Sun Java plug-in version 1.3.1 or greater. You must download the Java Virtual Machine applet and install it on the client machine. (The Java Virtual Machine applet is available at http://www.hp.com/servers/manage/jvm.) User administration and security Enables additional users with custom access rights, provides secure password encryption, and uses Secure Sockets Layer (SSL) encryption of HTTP data transmitted across the network. Virtual power button Enables remote operation of a power button on a host server.
