Product Description
The ProLiant ML350 Generation 2 (G2) is the second update of the ProLiant ML350 since its
introduction in January 2000. Although the model launched in October 2000 was sometimes
identified as the second generation ProLiant ML350, it should now be identified as the 1.0GHz
model.
The Compaq ProLiant ML350 G2 models support two Intel Pentium®III 1.13GHz or 1.26GHz
processors with Flip-Chip Pin Grid Array (FC-PGA) technology and 512KB of Level 2 (L2) ECC
cache memory.
What’s New
New, upgraded features, or feature offerings that have changed include:
■Support for up to two 1.13 or 1.26GHz Tualatin Pentium®III Processors with FC-
PGA technology, and 133MHz front-side bus (FSB)
■Socketed VRM 8.5 Processor Power Modules (PPMs) for each installed CPU
■Integrated 512KB of L2 full speed cache
■Tower or rack form factors (5U)
■350W hot-pluggable (HP) power supply, redundant power supply option (1+1)
■No hard drive shipped standard
■Ten internal drive bays:
Four 5.25” x 1.6” removable media bays, one filled with 40X IDE CD-ROM
drive, one filled with 1.44MB carbon floppy diskette drive, two available
Six 6” x 1” wide Ultra2/Ultra3 Hot Plug Drive bays
■Internal Two Bay Hot Plug Wide Ultra2/Ultra3 SCSI Drive Cage option
■Internal storage capacity of 436.8GB (6 x 72.8GB 1”), up to 509.6GB (including two
36.4GB non-hot-plug drives in the two available removable bays) or up to 582.4GB
(including an optional internal 2-bay hot-plug drive cage with two 72.8GB hot-plug
drives installed)
■Seven Non-Hot Pluggable (NHP) expansion slots (6 available):
Five 64-bit/33MHz PCI
One 32-bit/33MHz PCI
The Server Feature Board installed in its own dedicated slot
■Integrated ATI Rage XL video controller — upgraded to 8MB SDRAM and
embedded on the Server Feature Board
■Two new ROM technologies:
Compaq Remote ROM Flash Utility
Redundant ROM

Rev. 1.0 Page 4 of 24
■Upgraded from Automatic Server Recovery (ASR) to ASR-2, and upgraded to
SmartStart version 5.20
■Pre-Execution Environment (PXE) support—enables remote configuration and
installation of operating system
■Tool free entry to chassis and access to components
■3-3-3 warranty, Pre-Failure Warranty covering processors, memory and hard drives
Processor Technology
In addition to the changes bulleted above, the FC-PGA2 processors now include an integrated
heat spreader above the flip-chip core, making them easier to cool. They also now have an
attached heatsink, solving the problems faced when the processor and heatsink were separated
and then reattached.
Both processors are powered by socketed +12V input VRM 8.5 Processor Power Modules
(PPMs). .13 –micron technology enables smaller, less expensive chips that run faster and require
less power.
Compaq Remote ROM Flash Utility
This utility allows administrators to upgrade the system ROMs as well as the supported Compaq
Smart Array controllers on multiple servers from a remote location. The ROM upgrades can
either be flashed individually or batched together to perform multiple ROM upgrades all at once.
Redundant ROM
If the server either loses power during a ROM flash or if the flash process is otherwise
interrupted, redundant ROM allows you to restart the system with the original ROM image.
Redundant ROM also allows you to use RBSU to switch between two ROM images for testing
and evaluation purposes. Through RBSU (F9 Setup)Advanced Options Redundant
ROM, you can restart the server using the previous ROM image if a new ROM flash doesn’t
meet your expectations. This eliminates the need to use the ROMPAQ Flash Utility to fall back
to the previous ROM version.
Automatic Server Recovery-2 (ASR-2)
Like ASR, ASR-2 resets the system in the event of a catastrophic operating system error and it
restarts the server within a predetermined amount of time after the system stops responding. For
ASR-2, however, system administrators can set the interval in the RBSU.
Next Generation Remote Insight Support
The ML350 G2 has two connectors on the system board to support Remote Insight, Lights-Out
Edition boards. The 16-pin connector will support the existing board, while the 30-pin connector
will support the next generation board.
Hot-Pluggable Power Supplies
The ProLiant ML350 G2 comes standard with a hot-pluggable power supply. The hot-pluggable
redundant power supply option offers a 1+1 configuration. In this configuration, both power

supplies send power to the power supply backplane. If one power supply fails, the other will
continue to keep the server operational.
Ultra 3 Hot-Plug (HP) Drive Cages
The ProLiant ML350 G2 supports six Low Voltage Differential SCSI (LVDS) Wide Ultra3 SCSI
hot-pluggable (HP) hard drives. Each 1-inch bay can hold a 72.8GB 10,000-rpm hard drive
(436.8GB total). These drives operate on one channel of the integrated SCSI controller. The
second channel can operate either an external secondary storage system or an internal or external
tape backup device.
Non-Hot Plug (HP) Media Bays
Two optional non-HP drives can be mounted in the removable media bays to increase the total
internal storage capacity to 509.6GB.
Internal Two Bay Hot Plug (HP) Wide Ultra2/Ultra3 SCSI Drive Cage Option
Alternatively, a 2-bay SCSI drive cage with one 1” and one 1.6” drive bay, installed in two
available removable media bays is available as an option. This cage supports two HP 72.8GB
drives that can increase the internal storage capacity to 582.4GB.
Enhanced Fan Control
A temperature-sensing device located near the processors now monitors the temperatures of both
processors and the ambient temperature of the chassis. When any of these three temperatures
reaches a predefined limit, the fan speed increases to control the temperature in the system.
Server Feature Bus
The Server Feature Bus is a proprietary bus that has PCI and management signals. Running the
management signals through this bus eliminates the need for the System Management Interface
Cable (SMIC) that was compulsory in the first generation of the ProLiant ML350.
Server Feature Board
The server feature bus slot, located at the bottom of the system board, houses the Server Feature
Board. This board contains the hard drive, NIC, video, and management controllers.
Drive and network activity is passed over the server feature bus to the LEDs on the front of the
chassis. This eliminates the need for a System Management Interface Cable (SMIC) on the board
and simplifies removal and replacement procedures.
NMI Debug Button
The NMI Debug button is located on the Server Feature Board. NMI is a diagnostic mechanism
that allows for crash dump files to be created in situations when a system is hung and unable to
respond to traditional debug mechanisms. The NMI Debug button can be used to diagnose
software failures by forcing the operating system to invoke the Non-Maskable Interrupt (NMI)
handler and generate a crash dump log. This log can provide critical troubleshooting information
that may be difficult or impossible to obtain through other means.

Compaq ProLiant ML350 G2 Service Overview 6
Rev. 1.0 Page 6 of 24
The user initiates a Non Maskable Interrupt (NMI) by pressing the NMI Debug button. The NMI
can allow a hung system to become responsive enough to generate a crash dump log. The button
is enabled/disenabled in RBSU.
Warning! The NMI Debug button causes the unit to abruptly fail, as it is designed to do.
Therefore, it should never be used during normal operation.
ASR-2 is used when an automated crash dump is desired. Normally, ASR-2 provides a system
reset; however, ASR-2 can be configured to generate the NMI Crash Dump instead of a reset.

Unit Identification (UID) LEDs
Blue Unit Identification (UID) LED indicators on the front and back of the server help identify
the server in large rack deployments. If you press the UID button on the front of the server, the
corresponding UID LED on the back of the server1lights to identify it as the server being
serviced.
Server Health LEDs
Three server health LED indicators are located on the front of the ProLiant ML350 G2 between
the UID button and the Power On/Standby LED. These indicate the status of the:
■Internally serviceable components (processor, PPM, memory subsystem, temperature
control, Server Feature Board, and fans)
■Externally serviceable components (hot-pluggable power supplies)
■Embedded NIC
The NIC information is also represented on the rear panel with the three LEDs located above the
RJ-45 connector.
For detailed information on the system status and network controller LEDs, refer to Appendix E
in the Setup and Installation Guide. (See References at the end of this document.)
System Board LEDs
In addition to the system status LEDs, the ProLiant ML350 G2 now includes 11 diagnostic LEDs
on the system board. These LEDs indicate error conditions, such as processor, PPM, or memory
module failures. Refer to the graphic and table on the following pages to determine what these
lights indicate.
