Hardware Specification

SATA Backplane:

A power MOSFET to provide per disk power (5V and 12V) for each disk spin-up

control.

A uP to control the disk spin up function i f LED board enable this funct ion, set by a

DIP switch pin, and start from the lowest posit ion backplane. (i.e. the top one

would be the latest to spin up.

5 fan connectors (3 pins): each support 12V current up to 750mA (max power

consumption: 9 watts)

A 4x3 jumper wi th 4-dig it jumper cap is added to select either disk power or disk

activity fo r LED indication.

A design hook with a zero ohm resistor to conduct disk reserved pin (P11) to

disk activ ity LED. (Its for the case that the pin is defined for disk LED output)

Multiple SATA backplanes (up to 4) is cascaded by a connector to report fan, disk

and thermal s ignals:

1 thermal signal per SATA backplane report ing to LED module

4 disk activity (or present) signals per SATA backplane reporting to LED

module

5 fan speed signals (for all SATA backplane) reporting to LED module

A pre-charge circu it for surge current protection when a disk is plugged in.

2 standard big-4P (Molex device connector) power inlets

LED Module (for 2U/3U/4U)

1 power button and 1 reset button

1 buzzer for alerting and 1 alarm mute button (controlled by uP)

2 standard USB 1.1/2.0 ports

1 connector for RPS (Redundant Power Supply) fault event detection

1 connector with signal controlled by uP to mute RPS built-in audio alarm

1 connector with I2C signals as a design hook to support peripheral management

interface

1 connector to gather fan speed, disk activ ity, and thermal signals from SATA/SCSI

backplane by a FFC cable

Total 16 (4x4) LEDs for disk activity signal from 4 backplane

4 thermal signal inputs from 4 backplane (detected by uP)

Total 5 fans supported

5 mono LEDs: Power, LAN1, LAN2, HDD and Fan/Thermal event LEDs
