• 4-11 Front Cooling Fans

The front cooling fan module consists of a control board, a hard disk drive
LED message LED board, and two cooling fans. The hard disk drive mes­sage LED board mounted in the front of the cooling fan module consists of
five sets of LEDs to represent the status of up to five hard disk drives. Each
set has three LEDs which can show the power, activity, and status of each
hard disk drive.

The front cooling fans’ main purpose is to cool the hard disk drives. These
fans can be removed by using a small screw driver to push the eject mecha­nism in the fan module. The eject mechanism is behind a small hole as boxed
on page 29. There are two individual 2 1/4 inch (6cm) fans secured by four
screws on each fan. The ASMA (ASUS Server Management Agent) software
will report an error message when any of these two fans malfunctions.

Power Supply Components

The redundant power supply consists of two identical ATX power modules.
The LED indicators light when both the input and output voltages are stable,
and dim when either the input or output voltage fails. A button located on
the bottom-right corner of the power supply disables the sounding of the
audible alarm.

Power Module Rating

The power modules are rated at 300W each and have passive current shar ­ing on all outputs. Each power module supplies up to 300W to share the
load but two modules combined do not provide 600W. If one power mod­ule fails, 300W load is supported using one power module.

IMPORTANT

Before turning on the server, make sure the power input voltage
is set to comply with the standard used in your country (220V­240V or 110-120V).

NOTE

An optional 400W standard power supply module may be or­dered on demand.

• 5-1 SCSI Cable Limits

SCSI cables have a limit to the length that it may have. Exceeding the length
may cause problems mounting or using any one of the SCSI devices.

CAUTION

Exceeding the SCSI cable limits may cause unreliable data trans­fers even if all the devices are mounted properly.

Cable Limits Max Data Transfer Rates Max Devices

1) 12m (29.4ft) Ultra2-SCSI (68 pin 80MB/Sec) 15

2) 3m - 1.5m Wide Ultra-SCSI (68 pin 40MB/Sec) 4 - 8

3) 3m (9.8ft) Wide-SCSI (68 pin 20MB/Sec) 15

4) 3m - 1.5m Narrow Ultra-SCSI (50 pin 20MB/Sec) 4 - 7

5) 3m (9.8ft) Narrow Fast-SCSI (50 pin 10MB/Sec) 7

IMPORTANT

• Narrow refers to 50 pin and Wide refers to 68 pin. Don’t get
confused by the width of the connector or cable.

• The SCSI ID for devices on one connector cannot be the same
as the SCSI ID for devices on the other connectors. None of
the devices on any connector can use ID7, which is reserved
for the SCSI controller.

• A maximum of 15 devices may be connected to the mother-
board (three connectors) at one time.

NOTE

• A total of 15 “Ultra2-SCSI” devices (ID0-ID15) may be connected

to the 68-pin Ultra2 connector on the motherboard.

• If connecting Fast/Ultra devices with Ultra2 devices on the

Ultra2 connector, the entire SCSI bus will be limited to the
Ultra SCSI conditions listed above. Mixing SCSI devices is
highly not recommended.

• A total of 8 “Wide Ultra-SCSI” devices (ID0-ID15) may be con-

nected to the 68-pin W ide connector if using a 1.5m (4.9ft) cable,
but only 4 “Wide Ultra-SCSI” devices if using a 3m (9.89ft)
cable. Ultra-SCSI technology is unstable over long lenghts, there­fore stability will depend on they quality of your cable and de­vices.

• A total of 15 “Wide-SCSI” devices (ID0-ID15) may be con-

nected to the 68-pin Wide connector.

• A total of 7 “Narrow Ultra-SCSI” devices (ID0-ID6) may be

connected to the 50-pin Narrow connector when using 1.5m
(4.9ft) cable but only 4 devices when using 3m (9.8ft) cable.
Ultra-SCSI technology is unstable over long lengths, therefore
stability will depend on the quality of your cable and devices.

• A total of 7 “Narrow Fast SCSI” devices (ID0-ID7) may be

connected to the 50-pin Narrow connector.

ASMA (Asus Server Management Agent)

ASUS Server Management Agent is an SNMP software that provides hard­ware monitoring information to the Network Management Station (NMS).
ASMA can report the computer fan speeds, working voltage, system tem­perature, and chassis intrusion events to the NMS. It can also enable or
disable Automatic Server Restart (ASR) function from the NMS.

Hot-Swap

A hot-swap is the replacement of a connected device such as a hard drive
without shutting down the computer system.

LVDS (Low Voltage Differential Signaling)

LVDS sends each data bit with two wires instead of one, reducing noise
susceptibility and electromagnetic interference, allowing greater device con­nectivity and higher transmission frequencies.

RAID (Redundant Array of Inexpensive Disks)

RAID can be set up to provide mirroring (for fault tolerance), parity (for
data guarding), or striping (for data distribution over several drives for in­creased performance).

RJ-45

An 8-pin connector used in many computer networking devices. Female
connectors are found on hardware devices, whereas male connectors are
found on twisted pair cabling used to connect two networking devices.

SCA (Single Connector Attachment)

SCA is a technology that incorporates both power and signal into an 80-pin
interface. The SCA interface is designed to facilitate hardware installation
and to support hot-swapping.
