System Description 11

Peripherals

External Bay for 5.25-inch Removable Media Devices

The chassis has a bay for two 5.25-inch half-height peripherals that is accessible from the front of

the system. This bay is intended to provide space for CD-ROM, tape backup or other removable

devices.

You can convert the 5.25-inch bays to a single full-height bay. We recommend that you do not use

this bay for hard disk drives, because they generate EMI, ESD susceptibility increases, and the

drive will not be adequately cooled.

Internal Bay for 3.5-inch IDE Hard Drives

The chassis has a 3.5-inch bay for two half-height or 1-inch high IDE hard drives. The bay is not

externally accessible.

Hot-swap Bay

A hot-swap bay is provided for five SCSI SCA2 hard drives that are 3.5 inches wide and 1 inch

high. The bay is designed for drives that consume up to 17 watts of power each. Drives must be

specified to run at a maximum ambient temperature of 50 C.

The system was designed to allow the user to install a Redundant Array of Independent Disks

(RAID). A software implementation with onboard SCSI or an add-in RAID controller card can be

used to set up RAID applications.

SCSI Hot-swap Backplane

The hot-swap backplane provides the following:

Five Single Connector Assembly (SCA2) connectors for SCA2-compatible SCSI drives

Power control for each drive, including automatic slot-power-down upon removing a drive

Signal for a fault indicator on the front panel for each drive

Internal IMB (Intelligent Management Bus)

Two +12 V connectors for a fan with tachometer

Local IMB-based temperature sensor

The SCSI hot-swap backplane provides control signals and power for five Ultra2/LVD 3.5-inch,

1-inch high, SCA2 SCSI hard disk drives. The backplane receives control signals from the SCSI

controller on the server board through a cable connected to the wide SCSI connector on the

backplane. The backplane is powered through cables connected to the two power connectors.

The drives get their control signals and power from the SCA2 connectors on the backplane.

The fault indicators on the front panel indicate failure status for each drive in the bay. These

indicators get their signals through a cable connected to the front panel connector on the

backplane.

12 Intel Astor II Server Chassis Subassembly Product Guide

The temperature sensor on the backplane provides temperature information to the BMC (baseboard

management controller) on the server board through chassis service messages.

The backplane power control will power down a drive when a failure is detected and reported to

the SCSI bus. When a new drive is inserted, the power control waits a short time for the drive to

become fully seated and then applies power to the drive.

Power Supply

The 300 watt PFC (power factor correction) universal type power supply is designed to minimize

EMI. The supply operates within the following voltage ranges and is rated as follows:

100-120 V at 50/60 Hertz (Hz); 4.6 A maximum

200-240 V at 50/60 Hz; 2.3 A maximum

The DC output voltages of the power supply are +5 V, +12 V, +3.3 V, -5 V, -12 V, and

+5 V standby. Power to the server board is provided through the power cable to the 24-pin main

power connector.

Checking the Power Cord

WARNING

Do not attempt to modify or use a supplied AC power cord if it is not the

exact type required.

If a power cord supplied with the system is not compatible with the AC wall outlet in your region,

get one that meets the following criteria:

The cord must be rated for the available AC voltage and have a current rating that is at least

125% of the current rating of the system.

The connector that plugs into the wall outlet must be a grounding-type male plug designed

for use in your region. It must have certification marks showing certification by an agency

acceptable in your region.

The connector that plugs into the AC receptacle on the system power supply must be an IEC

320, sheet C13, type female connector.

In Europe, the cord must be less than 4.5 meters (14.76 feet) long, and it must be flexible

<HAR> (harmonized) or VDE certified cordage to comply with the system's safety

certifications.

System Cooling

The chassis includes four tachometer fans for cooling and airflow. One of these is the integrated

fan in the power supply.

✏

NOTE

The chassis side cover must be on the system for proper cooling.

System Description 13

System Security

To help prevent unauthorized entry or use of the system, the chassis includes a chassis intrusion

switch that can be monitored by Server Management software and two padlock loops.

Mechanical Locks

A padlock loop on the rear of the system side cover can be used to prevent access to the

microprocessors, memory, and add-in cards. A variety of lock sizes can be accommodated by the

.300 diameter loop.

A padlock loop on the hard drive bay EMI door provides security for the hot swap hard drives.

The allotted space accommodates a MasterLock

†

model 120-D or equivalent lock. Dimensions:

.815” H x .830” W x .430” D. Pall diameter .145”

Monitoring

Install the chassis intrusion switch. When the side cover is removed, the switch transmits a signal

to the BMC on the server board. Server management software can be programmed to respond to

an intrusion by powering down or by locking the keyboard, for example.

2 Working Inside the System

Tools and Supplies Needed

Phillips (cross head) screwdriver (#2 bit)

Antistatic wrist strap (recommended)

Needle-nosed pliers

Safety: Before You Remove the Side Cover

Before removing the system side cover for any reason, observe these safety guidelines.

1. Turn off all peripheral devices connected to the system.

2. Turn off the system by pressing the power button on the front of the system. Then unplug the

AC power cord from the system or wall outlet.

3. Label and disconnect all peripheral cables and all telecommunication lines connected to I/O

connectors or ports on the back of the system.

4. Provide some electrostatic discharge (ESD) protection by wearing an antistatic wrist strap

attached to chassis ground of the system—any unpainted metal surface—when handling

components.

Warnings and Cautions

These warnings and cautions apply whenever you remove the side cover of the system to access

components inside the system. Only a technically qualified person should integrate and configure

the system.

WARNINGS

The power button (a convex button) on the front panel DOES NOT turn

off the system AC power. To remove power from system, you must

unplug the AC power cord from the wall outlet or the system.

Hazardous electrical conditions may be present on power, telephone,

and communication cables. Turn off the system and disconnect the

power cords, telecommunications systems, networks, and modems

attached to the system before opening it. Otherwise, personal injury or

equipment damage can result.

Hazardous voltage, current, and energy levels are present inside the

power supply. There are no user-serviceable parts inside it; servicing

should be done by technically qualified personnel.

16 Intel Astor II Server Chassis Subassembly Product Guide

CAUTIONS

ESD can damage disk drives, boards, and other parts. Perform all

procedures in this chapter only at an ESD workstation. If one is not

available, provide some ESD protection by wearing an antistatic wrist strap

attached to chassis ground any unpainted metal surface on your system

when handling parts.

Always handle boards carefully. They can be extremely sensitive to ESD.

Hold boards only by their edges. Do not touch the connector contacts. After

removing a board from its protective wrapper or from the system, place the

board component side up on a grounded, static free surface. If you place the

server board on a conductive surface, the battery leads may short out. If

they do, this will result in a loss of CMOS data and will drain the battery.

Use a conductive foam pad if available but not the board wrapper. Do not

slide board over any surface.

For proper cooling and airflow, always install the chassis side cover before

turning on the system. Operating it without the cover in place can damage

system parts.

Removing the Side Cover

You need to remove the chassis side cover, and in some cases the front cover, to gain access to

components inside the system.

1. Observe the safety and ESD precautions at the beginning of this chapter.

2. Turn off all peripheral devices connected to the system.

3. Turn off the system by pressing the power button on the front panel, AND unplugging the AC

power cord.

4. Label and disconnect all peripheral cables attached to the I/O panel on the back of the system.

5. Remove and save the three screws from the side cover; you will need them later to reattach the

cover.

6. Place the fingertips of your left hand under the built in handle on the back of the cover.

7. Using an even pull, slide the cover backward, about an inch, until it stops.

8. Using your left hand, pull the back end of the cover toward you to disengage its bottom row of

tabs from the notches in the chassis.

9. Using both hands, lift the cover upward to disengage the top row of tabs from the notches in

the top edge of the chassis. Set the cover aside.
