2 Removal and Replacement Procedures This chapter provides subassembly/module-level removal and replacement procedures for system components. After completing all necessary removal and replacement procedures, verify that all components operate properly by running the appropriate diagnostic software: • • For server blade components, run the Server Diagnostics Utility, available at www.hp.com. For server blade enclosure and power enclosure components, run the infrastructure diagnostics.
Removal and Replacement Procedures WARNING: To reduce the risk of injury from high-current electrical energy, do not remove the server blade access panel when power is applied through the HP ProLiant p-Class diagnostic station. Remove all power from the server blade before removing the access panel. WARNING: Setting the server blade power button to the standby position removes power from most areas of the server blade.
Removal and Replacement Procedures WARNING: To reduce the risk of personal injury or damage to the equipment, at least two people are needed to safely unload the rack from the pallet. An empty 42U rack weighs 115 kg (253 lb), is over 2.1 m (7 ft) tall, and may become unstable when being moved on its casters. Do not stand in front of the rack as it rolls down the ramp from the pallet, but handle the rack from both sides.
Removal and Replacement Procedures Server Blade Components Use the procedures in this section to perform service events on ProLiant BL20p G3 server blades. NOTE: Slate blue denotes serviceable parts, and port denotes hot-pluggable parts. Server Blade Preparation To service any internal server blade component, power down the server blade and remove it from the server blade enclosure. CAUTION: Electrostatic discharge can damage electronic components.
Removal and Replacement Procedures To service internal server blade components: 1. Identify the proper server blade in the server blade enclosure. 2. Remove power from the server blade in one of the following ways: — Use the Virtual Power Button feature in the iLO Remote Console to power down the server blade from a remote location. Be sure that the server blade is in standby mode by observing that the power LED is amber. — Press the power button on the front of the server blade.
Removal and Replacement Procedures 3. Remove the server blade from the server blade enclosure: a. Press the release button (1). CAUTION: After you press the release button, the server blade is unlocked from the enclosure. Use both hands to support the server blade when you remove it from the rack. b. Open the lever (2). c. Grasp the lever and slide the server blade from the enclosure (3). Place a hand under the server blade to support it as you remove it from the enclosure.
Removal and Replacement Procedures Access Panel To remove the access panel: 1. Power down the server blade and remove it from the server blade enclosure. Refer to the “Server Blade Preparation” section in this chapter. 2. Loosen the thumbscrew (1). 3.

3 Diagnostic Tools ProLiant BL p-Class Diagnostic Tools Use the following tools to diagnose problems, test hardware, and monitor and manage system operations. Table 3-1: Diagnostic Tools Tool Description How to run the tool Array Diagnostics Utility (ADU) ADU is designed to run on all HP systems that support HP array controllers. ADU collects information about the array controllers in the system and generates a list of detected problems.
Diagnostic Tools Table 3-1: Diagnostic Tools continued Tool Description How to run the tool ROMPaq Utility The ROMPaq Utility checks the system and provides a choice of available ROM revisions and controller firmware. You can download this utility from the HP website: Survey Utility gathers critical hardware and software information on server blades.
Diagnostic Tools HP ProLiant Essentials Rapid Deployment Pack (RDP) The optional HP ProLiant Essentials RDP is the preferred method for rapid, high-volume server blade deployments. The RDP includes Altiris eXpress Deployment Server and the SmartStart Scripting Toolkit. Install the CD in the CD-ROM drive of the administrator workstation or client PC and refer to the documentation that ships with the software. ROM-Based Setup Utility (RBSU) RBSU configures the hardware installed in the server blade.

The drive has failed and has been placed offline. Off On Off OK to replace the drive online if a predictive failure alert is received, provided that the array is configured for fault tolerance and all other drives in the array are online. The drive is online and configured as part of an array.
Connectors, LEDs, and Switches Buttons and Switches Use the following sections to identify the locations and functions of push-button and system switches. Buttons Use the “Power Button” section to identify push-button switches on the system hardware. Power Button Setting the server blade power button to the standby position removes power from most areas of the server blade. This process may take 30 seconds, during which time some internal circuitry remains active.
Connectors, LEDs, and Switches Switches System switches enable you to change certain settings or to perform advanced diagnostic procedures. The following sections explain the functions of each switch. Use Figure 4-8 and Table 4-6 to identify switch locations and functions.
Connectors, LEDs, and Switches NMI Switch Crash dump analysis is an essential part of eliminating reliability problems such as hangs or crashes in operating systems, device drivers, and applications. Crashes can freeze a system, requiring you to do a hard reset. Resetting the system erases any information that supports root cause analysis. Systems running Microsoft Windows 2000 experience a blue-screen trap when the operating system crashes.
Connectors, LEDs, and Switches 7. Power up the server blade: — Press the power button on the front of the server blade. — Use the virtual power button feature in the iLO remote console. 8. Wait for the POST message that prompts you to change the switch setting: Maintenance switch detected in the "On" position. Power off the server and turn switch to the "Off" position. 9. Repeat steps 1 through 3. 10. Change position 6 of SW2 to off. 11. Repeat steps 5 through 7.
Connectors, LEDs, and Switches 9. Repeat steps 1 through 3. 10. Change positions 1, 5, and 6 of SW2 to off. 11. Repeat steps 5 through 7. If both the current and backup versions of the ROM are corrupt, you must return the system board for a service replacement. For spare part numbers, refer to Chapter 1, “Illustrated Parts Catalog.
