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 from the HP website: 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 On/Standby 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 G2 server blades. NOTE: Slate blue denotes serviceable parts, and port denotes hot-pluggable parts. Server Blade Preparation To service any internal server blade component, you must power down the server blade and remove it from the server blade enclosure. CAUTION: Electrostatic discharge can damage electronic components.
Removal and Replacement Procedures Figure 2-1: Pressing the Power On/Standby button 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.

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 HP Diagnostics HP Diagnostics tests and verifies operation of HP hardware. If HP Diagnostics finds a hardware failure, it isolates the replaceable part, if possible. Access HP Diagnostics when POST detects a system configuration error. For a complete list of POST error messages, refer to the HP ProLiant Servers Troubleshooting Guide. HP Diagnostics can be downloaded from the HP website: http://h18000.www1.hp.
Diagnostic Tools Table 3-1: Diagnostic Tools continued Tool Description How to run the tool Option ROM Configuration for Arrays (ORCA) The ORCA Utility is a menu-driven utility that does not require a CD and can be started when the server blade is booting. This utility enables users to perform the following functions: Run ORCA by pressing the F8 key during POST.

Use Figure 4-6 and Table 4-4 to identify LED locations and functions.
Connectors, LEDs, and Switches Table 4-4: ProLiant BL20p G2 Server Blade Front Panel LEDs Item LED Description Status 1 Unit identification Blue = Flagged Blue flashing = Management mode Off = No remote management 2 Health Green = Normal status Flashing = Booting Amber = Degraded status Red = Critical status 3 NIC 1 Green = Linked to network 4 NIC 2 Green flashing = Network activity 5 NIC 3 Off = No activity 6 Power On/Standby Green = On Amber = Standby (power available) Off = Unit off
Connectors, LEDs, and Switches Table 4-5: Hot-Plug SCSI Hard Drive LEDs 1 Activity 2 Online 3 Fault Means On Off Off Do not remove the drive. Removing a drive during this process causes data loss. The drive is being accessed and is not configured as part of an array. On Flashing Off Do not remove the drive. Removing a drive during this process causes data loss. The drive is rebuilding or undergoing capacity expansion. Flashing Flashing Flashing Do not remove the drive.
Connectors, LEDs, and Switches Switches Use the following sections to identify the locations and functions of push-button and system switches. Buttons Use the “Power On/Standby Button” section to identify push-button switches on the system hardware. Power On/Standby Button Setting the server blade Power On/Standby 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 System 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 4-9 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 On/Standby 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 SW4 to off. 11. Repeat steps 5 through 7.
Connectors, LEDs, and Switches Accessing the Redundant ROM If the system ROM is corrupted, you can set the system to use the backup version or redundant ROM. To use the redundant ROM: 1. Power down the server blade: — Press the Power On/Standby button on the front of the server blade. — Use the virtual power button feature in the iLO remote console. 2. Disconnect the server blade from all power sources: — Remove the server blade from the enclosure and set it on a flat, level surface.
