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.

■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

Compaq ProLiant ML350 G2 Service Overview 5

Rev. 1.0 Page 5 of 24

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.
