PROCEDURES
This guide provides detailed maintenance and service information for the
Compaq ProLiant 4500R Rack-Mountable Server.
RACK MOUNTABLE PRODUCTS SERVICE
GUIDELINES
Follow these guidelines when removing or replacing components.
WARNING: Before loading any components in the rack, be sure that the rack
leveling feet are extended to the floor, that the rack is stable and level, and that
the full weight of the rack rests evenly on the leveling feet, not on the casters.
Be sure that you have either attached the stabilizing feet or coupled multiple
racks.
WARNING: Always ensure that the rack is adequately stabilized before
extending a component outside the rack, and extend only one component at a
any reason.
WARNING: Be careful when pressing the component rail latches on both
sides of the component. Pressing the latches in at the same time while sliding
the component in on its rails, could pinch your fingers in the latch.
n Allow a minimum clearance of 30 inches between the wall and the rack to provide adequate
access.
n Load the heaviest components first, and load the rack from the bottom up. Refer to the Rack
Builder software to provide optimal installation order.
n Ensure that the rails are properly aligned. Push the component completely into the rack and
secure it in place with the four thumb screws on the component face plate before working on
the next component.
n Make sure the previously installed component is secured to the rack by its thumb screws; then
install the next component.
GENERAL REMOVAL AND

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:
n Transport products in static-safe containers such as conductive tubes, bags, or boxes.
n Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
n Cover work stations with approved static-dissipating material. Provide a wrist strap
connected to the work surface and properly grounded tools and equipment.
n Keep work area free of non-conductive materials such as ordinary plastic assembly aids and
foam packing.
n Always be properly grounded when touching a static-sensitive component or assembly.
n Avoid touching pins, leads or circuitry.
n Always place drives PCB assembly side down on the foam.
n Use conductive field service tools.
PREPARATION PROCEDURES
Before beginning any of the removal and replacement procedures (excluding Hot-Pluggable hard
drives), complete the following steps:
1. Power the system down cleanly according to your operating system.
2. Turn the server off.
CAUTION: Never turn a storage system off before the server controlling it has
been turned off. Doing so will cause the controller to mark the drives as failed.
3. Turn the Storage System off.
4. Disconnect the AC power cord from the AC outlet, then from the system.
5. Disconnect all external peripheral devices from the computer.
WARNING: High voltage is present. Extreme care must be taken when

Hot-Pluggable Hard Drives
Hot-Pluggable hard drives used in combination with the Compaq Smart SCSI Array Controller
can be replaced while the power is still on.
NOTE: It is not necessary to set the SCSI ID jumpers on a Compaq replacement HotPluggable hard drive. The SCSI ID is set automatically by the backplane board and the
Hot-Pluggable tray when the drive is installed.
CAUTION: Before removing any Hot-Pluggable hard drive, read the guidelines listed in
the following section.
Maintenance and Service Guide
2-6 Removal and Replacement Procedures
Important Guidelines About Replacing
Hot-Pluggable Hard Drives
When a drive configured for fault tolerance is replaced, the replacement drive will automatically
begin being restored when it is installed. When a drive is in the process of being restored, the
On-line LED will flash green. The LED will continue to flash until the drive is completely
restored.
Figure 2-4. Hot-Pluggable Hard Drive LED Indicators
When replacing Hot-Pluggable hard drives, these guidelines must be followed:
n 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(s).
n Never remove a working drive when another drive has failed. Drives that have been
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 when replacing a failed drive.
n Never remove a drive while another drive is being rebuilt. A drives' On-line LED will be
flashing green whenever it is being rebuilt. A replaced drive is restored from data stored on
the other drives.
n Never turn a ProLiant Storage System off while the Server controlling it is powered on.
Doing so will cause the server's SMART Controller to mark the drives as "failed." This
could result in permanent data loss.
n If an on-line spare drive is installed, wait for it to complete rebuilding before replacing
the failed drive. When a drive fails, the on-line spare will become active and begin being
rebuilt as a replacement drive. Once the on-line spare has completed being rebuilt (On-line
LED will be on solid), the failed drive should be replaced with a new replacement drive. Do
not replace the failed drive with the on-line spare.
n A POST error message (1786) will occur when the system is turned on if a drive(s) has
been replaced while the system is OFF. When this occurs you will be prompted to:
PRESS F1 TO BOOT THE SYSTEM AND REBUILD THE REPLACED DRIVE OR,
PRESS F2 TO BOOT THE SYSTEM AND NOT REBUILD THE DRIVE(S).
CAUTION: Pressing F2 will cause permanent data loss to the entire logical drive. F2
should be pressed only if all of the drives have been replaced or if complete data loss
is desired.
Maintenance and Service Guide
Removal and Replacement Procedures

NOTE: The Compaq ProLiant 4500R requires that RAM be installed in
correcting (ECC) memory is based on the parity scheme; one byte data, one bit
Compaq SIMMs or JEDEC-compliant SIMMs that conform to this parity scheme
increments of four SIMMs at a time. The SIMMs must be the same size and
speed. The specific SIMM bit pattern required to support error checking and
parity. The data byte and parity are constructed of DRAMs that are "n"
locations deep by 4-bits wide or 1-bit wide and "n" can be any number (that is,
"n" locations deep x 4-bits wide or "n" locations deep x 1-bit wide.) Use
only.
