Hot-Swap Tray Interface

The front of the hot-swap tray provides a keylock in order to switch the
power on, which also locks the handle, and switch the power off, which also
releases the handle. T wo LEDs provide information on the power and activ­ity status of the hard disk drive. When power is received by the hot-swap
tray’s connector board, the power LED will light. When data is written or
read to or from the contained hard disk drive, the activity LED will flash
proportional to the amount of data transferred.

Each SCSI backplane board supports four hard drives. If you are only in­stalling four or less hard drives in the hot-swap bays, only one SCSI
backplane board is needed. You may also use two SCSI channels and treat
each SCSI backplane board separately. The SCSI ID for the hard drives
used in each slot is determined by the SCSI ID DIP switch. The switch
controls two sets of SCSI IDs so individual ID settings cannot be made.

to insert the fan module. The in­dividual fans are secured by two
clips and two hooks. To release
these clips, use a screw driver to
push these clips in and then slide
the fan out. If an individual fan
fails, remove the fan and send it
back to the vendor for replace­ment. If all five fans fail, it may
be that the fan control board needs
replacing. Remove the control
board and send it back to your
vendor for replacement.

IMPORTANT

When replacing fans, be sure that the fan rotations are in the same di­rection. Use the manufacturer’s sticker on one side of the fan as a refer­ence as to the correct side. Air should flow from the front of the server

Power Module Rating

The redundant power supply consists of one frame and two identical ATX
power modules. The power supply must be turned on or off through an
ATX power switch connected to the motherboard’s panel connector. The
power modules are rated at 400W each and have passive current sharing on
all outputs. Each power module supplies up to 400W to share the load but
two modules combined do not provide 800W. If one power module fails,
400W load is supported using one power module.

CAUTION

Before turning ON your server for the first time, set the power
supply’ s voltage. Some products may have auto voltage switch­ing to accommodate 220V-240V or 110-120V but this power
supply must be set manually. The factory default should be on
230V to accommodate the higher voltage but it is safer to visu­ally inspect the switch yourself in case it is not. Using the power
modules set on 115V in 230V environments may cause damage
to the power modules.

IMPORTANT

For countries using 110V-120V , you must slide the switch to 1 15V
or else power up is not possible (but no damage will occur).

Power Module Failure

If any of the power modules fails to provide a voltage on any of its outputs,
an audible alarm (located in the frame) will sound and the failed power
module’ s LED will turn OFF. The power module’ s status LED lights when
both input and output voltages are stable and darkens if either the input or
output voltages fail. If the alarm sounds, perform the following steps:

1. Remove the power cord to the failed power module (with dark LED).

2. Remove the two screws and slide the failed power module out. The

alarm should stop. If not, there may be a problem with the other module
or with the redundant power supply frame (very unlikely).

3. Reinsert the failed power module and plug in the AC cord to confirm.

i. 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 motherboard
(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 Ul-

tra2 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 Wide connector if using a 1.5m (4.9ft) cable,
but only 4 “W ide 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 “W ide-SCSI” devices (ID0-ID15) may be connected

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 con-

nected to the 50-pin Narrow connector.
