Safety Considerations

Before performing service procedures, review the following safety information.

Electrostatic Discharge Information

A discharge of static electricity can damage static-sensitive devices or microcircuitry. Proper
packaging and grounding techniques are necessary precautions to prevent damage. To
prevent electrostatic damage, observe the following precautions:

• Transport products in static-safe containers, such as conductive tubes, bags, or boxes.

• Keep electrostatic-sensitive parts in their containers until they arrive at static-free

stations.

• Cover workstations with approved static-dissipating material. Use a wrist strap connected

to the work surface and properly grounded tools and equipment.

2

Service Preparation

• Keep the work area free of nonconductive materials, such as ordinary plastic assembly

aids and foam packing.

• Make sure you are always properly grounded when touching a static-sensitive component

or assembly.

• Avoid touching pins, leads, or circuitry.

• Always place drives PCB assembly-side down.

• Use conductive field service tools.

HP ProLiant DL760 Generation 2 Server Maintenance and Service Guide 2-1

2-2 HP ProLiant DL760 Generation 2 Server Maintenance and Service Guide

Service Preparation

WARNING: To reduce the risk of personal injury from hot surfaces, allow the internal
system components to cool before touching them.

CAUTION: Because the ProLiant DL760 G2 server does not have safety interlocks, it is

possible for a unit to be operated without the cover and air baffles properly installed. This
could cause thermal damage in the system and could void the warranty. The rack-mountable
ProLiant DL760 G2 server should always be operated with the system unit cover on. Proper
cooling cannot be achieved if the system unit cover is removed for extended periods of time.

CAUTION: Protect the server from power fluctuations and temporary interruptions with a
regulating uninterruptible power supply (UPS). This device protects the hardware from
damage caused by power surges and voltage spikes and keeps the system in operation
during a power failure.

Service Preparation

Powering Up the Server

When you power up the server, it should go through the following sequence. Record any
discrepancies and any error messages that occur. Be sure that the server is safely installed in
an adequate environment before powering up for the first time.

Be sure that power is supplied to each power supply on the back of the server. The IMD is
illuminated if the machine has power.

1. Turn on the machine by pressing the Power On/Standby switch.

2. Check the system power LED:
— The system power LED (1) as shown in Figure 2-4, should blink to indicate that the

system is trying to power up. If the LED does not blink when the power button is
pressed, then either one of the system components is improperly installed, or there is
no main power applied to the system power supplies.

— If the system power LED is amber or if the interconnect check lights are illuminated,

check the system interconnect status indicators (located on the top of the server). For
more information, refer to the “System I nterconnect LEDs” section of this chapter.

— The system power LED will blink every one to two seconds between a power-down

and power-up condition or immediately after applying power to the system. This
action indicates that the Power/On Standby switch has been pressed and that the
system will power up momentarily.

3. Check the power supplies on the back of the server. The following settings indicate that
the power switch is on and the power supply is in a “power-on del ay” mode:

— Top LED begins blinking (green)
— Bottom LED is on (solid green)
If the power supply top LED does not begin blinking (the server will not power up), refer

to the “System Interconnect LEDs” section in this chapter.
When the top LED illuminates solid green, listen for the fans to start.

4. Check the hard drive and CD-ROM drive LEDs on the front of the server. The hard drive
and CD-ROM drive LEDs should blink. If the LEDs do not light, verify that the hard
drives are fully installed in the system and the array bypass is initialized.

5. Check the memory cartridge LEDs. The memory cartridge attention and power LEDs
will illuminate solid and then go out in sequence beginning with memory cartridge 1 and
ending with memory cartridge 5 (left to right cartridge 1, 2, 3, 4, 5).

6. Check the DIMM status LEDs. The DIMM status LEDs for each cartridge will illuminate
solid and then go out in sequence beginning with cartridge 1 and ending with cartridge 5
(left to right cartridge 1, 2, 3, 4, 5).

2-10 HP ProLiant DL760 Generation 2 Server Maintenance and Service Guide

7. Watch for memory system initialization. Memory system initializes as the memory

cartridge power LEDs on all five memory cartridges begin blinking. After the memory
system is initialized, all memory cartridges power LEDs will illuminate solid.

8. The server begins the Power-On Self-Test (POST) sequence. The Integrated Management

Display (IMD) displays each step of the POST sequence.

Power-On Self-Test

As the POST process continues during server power-up:

1. Check for the IMD messages about the following:

a. Server name
b. LCD firmware
c. System initialization
d. PCI auto configuration
e. Video
f. Processors

Media Module Removal and Replacement Procedures

Hot-Plug Hard Drive Replacement Guidelines

You should be able to hot-plug a drive during normal activity. Be aware, however, that
replacing a hot-pluggable disk drive will affect system performance and fault tolerance.

NOTE: Depending upon the configuration, both a drive failure and the subsequent rebuild process will
cause storage subsystem performance degradation. For example, the replacement of a single drive on
an array with 50 logical drives will have less impact than if the array has only three logical drives.

Advanced Data Guarding

When a disk drive is hot-plugged, although the system is functionally operational, the disk
subsystem might no longer be fault tolerant. Fault tolerance will be lost until the removed
drive is subsequently replaced and the rebuild operation is completed. This procedure takes
several hours, even if the system is not busy while the rebuild is in progress. If another drive
in the array should incur an error during the period when fault tolerance is unavailable, a fatal
system error could result. If another drive fails during this period, the entire array contents
will be lost.

IMPORTANT: Perform disk drive replacement during low activity periods whenever possible. In
addition, a current valid backup of the logical drives in the array of the drive being replaced should be
available even if the drive replacement is being made during server downtime.

When replacing hot-plug hard drives in a fault-tolerant configuration, you must follow these
guidelines:

• Never remove more than one drive at a time. When a drive is replaced, the controller
uses data from the other drives in the array to reconstruct data on the replacement drive.
If more than one drive is removed, a complete data set is not available to reconstruct data
on the replacement drive.

• Never remove a working drive when another drive has failed. Drives failed by the
controller are indicated by the amber Drive Failure LED on the drive tray. Permanent
data loss will occur if a working drive is removed while a failed drive is being replaced.

• Never remove a drive while another drive is being rebuilt. A drive’s Online LED
flashes green while it is being rebuilt. A replaced drive is restored from data stored on the
other drives.

• Never turn a disk enclosure off while the initiator or controller is powered on or
active. Doing so can cause the initiator or controller to mark the drives as “f ailed.” This

action can result in permanent data loss.

• If a drive is replaced while the system is off, rebuilding the replaced drive might be
necessary. Follow the instructions on the screen or the instructions outlined in the system

reference guide.

CAUTION: During the boot prompt, pressing the F2 key will cause permanent data loss to
the entire logical drive. Press the F2 key only if all of the drives have been replaced or if
complete data loss is required.

4-8 HP ProLiant DL760 Generation 2 Server Maintenance and Service Guide

NOTE: When a drive configured for fault tolerance is replaced, the replacement drive automatically
begins restoring when it is installed. When restoring a drive, the Online LED blinks green. The LED
continues to flash until the drive is completely restored.
