This is from a newegg feedback. the manual is not on their site but according to this guy comments here it is to configure

Pros: It works.
Find documentation here:
There are extensive connections for fans, alarms and RAID cards (activity & error lights) . Configurable 'high temp' and fan alarms.

Cons: Documentation VERY hard to find.

For the drive trays, Blue power indicator, and green activity light are passed from back-plane to front of drive tray with 'light pipes'. The blue is too bright and bleeds into the green, making it difficult to see the activity lights.

Also, both power connectors need juice or the alarm on the tray goes off. Since I am not using redundant power supplies, I eventually used a 'Y' chord to apply power to both inputs. Not a big deal, just took a while to figure out why the alarm wouldn't ******* (this before I found the documentation mentioned above).

Other Thoughts: The cooling fan is LOUD. I'll look for a more quiet one in the future.

Hey how do you connect the power supply in a Chenbro RM22300 Case? Which one of the coloured cords goes to which plug on the psu? Any help would be greatly appreciated. Also this is for an Australian Power...

IMHO it doesn't matter if it is an Australian PSU. (Power Supply Unit)

The only thing that would change from country to country, is the AC electricity coming in.

Australia uses 220 Volts at 50 Hertz (Hertz stands for Cycles per Second)
Europe uses 220 Volts at 50 Hertz
USA uses 120 Volts at 60 Hertz
Japan uses 100 Volts at 50 Hertz

The PSU converts the AC electricity into DC electricity.
The DC voltage, and amperage is very small.

Now to the PSU and the Chenbro RM22300

Inside the chassis is a Chassis Management Board.
(It is a PCB
Printed Circuit Board)

Orient your view of the CMB (Chassis Management Board), with the blue dip switch to the bottom.
{Dip Switch is a rectangular blue block with 10 white dip switches }

To the right, and situated towards the bottom are two white Molex connectors.

(Actually they are each a 4-pin standard Peripheral power connector. Molex is a misnomer. It is the first company to produce a plug with this configuration. Sort of like calling an open-end adjustable wrench, a Crescent wrench)

This gives you more information on the 4-pin standard Peripheral power cable,

{The Red wire is 5 Volts DC
The Yellow wire is 12 Volts DC
The two Black wires are Ground wires.

Two D cell flashlight batteries produce 3 Volts DC }

There should be two 4-pin standard Peripheral power cables coming from the PSU.
They plug into the two white connectors mentioned above.

(The shape of the plug, and the connector on the CMB, will only allow the plug to be plugged in, in one direction)

There should also be a Purple cable.

The Purple cable plugs into JP1.

Looking at the CMB as stated above, there are two square looking connectors to the right of the board.
The one at the top is JP1.
(The one under JP1 is JM1)

I would also like you to have the User Manual.
Download it from Chenbro Support,

On this page left-click on the blue - DOWNLOAD - to the right of -
RM22300 - CMB User Manual for Windows - 899.8KB - 2010-07-13

This is a PDF file. {The computer you are using now has Adobe Reader on it, which uses PDF files}

After you click on the above link it may take up to 30 seconds before the first page will come up.
It may also take additional time for the file to fully download.
{Watch the download progress bar}

There is a way to save a copy of this file to your computer. If you are not aware of how to perform
this, and would like to, please post in a Comment.

{This way you will not have to download again.
You will also be able to burn a copy off to a CD, and have it for safekeeping.
You can also delete it from the computer you downloaded it on, and save Harddrive space }

Reinstall Hard Drive

  1. Step 1 Back up your data. Make sure you back up any important data stored on the hard drive in the event something goes wrong. Also, if you are selling or giving the hard drive to someone else, you should erase any data on the disk by formatting it.
  2. Step 2 Open the case. Remove any metal rings, watches or bracelets you may be wearing. Unplug the computer from the electrical outlet, then touch the metal casing to eliminate any static charge. You can also use an anti-static wrist strap if you prefer. Check the user's manual if necessary to determine how to open your particular PC case.
  3. Step 3 Locate the hard drive. Typically the hard drive will be connected to a flat 2 1/2 inch wide IDE cable and a power cable. Hard drives are often housed in removable metal cages which are secured to the computer case with one or more screws. Refer to your user's manual to locate the hard drive if necessary.
  4. Step 4 Disconnect the hard drive. Unplug the hard drive from the IDE and power cables. Grab the plastic IDE cable connector with your thumb and forefinger and gently pull until the connector breaks free. The power cable can be difficult to remove if the connector is fitted tightly. Make sure you don't bend any of the pins when disconnecting the cables.
  5. Step 5 Remove the hard drive. If the hard drive is fitted in a metal cage, locate and remove the screws that are holding the cage in place. Hold your hand under the cage to catch it if necessary. Once the cage is free, remove the small screws on either side of the hard drive to remove it from the cage. If the hard drive is connected directly to the computer case, simply remove the screws on each side of the hard drive and slide it out of the case.

Free Agent 1000GB is heating too much and stops working and want to know how to disassemble it to install a fan.

This is from another site, but I think it has a good description

Be careful, some people report that taking these drives apart may damage the connectors, that are soldered to a circuit board inside the case.

Try these steps, I looked at my own drive and it looks like it has the same design as the one described here.

1. Remove the rubber feet
2. remove the screws from where the rubber feet were.
3. Remove the esata/usb base
4. remove the lower plastic cover
5. remove the tiny screws
6. remove the metal shield
7. remove the 3 base screws.
8. stick a standard screw driver into the lower holes and twist. One side panel will move, one will not. The removeable panel is the one with the logo that lights up. If you are looking at the drive from the back where the ports are, the panel is on the left.
9. Stick the screwdriver between the plastic of the panel that moves. this panel has 4 clips holding it on very tightly but it can be pryed off.
10. Once the panel is open, unplug the drive and remove it. It is in a metal free floating cage. Remove the rubber covers to reveal the screws.
11. Pry the two cage panels apart and the drive is free. There is no permanent damage to the case, so you should be able to mount another drive in it.

Various laptop mount hard drives differently.
Some are mounted on the bottom of the laptop behind a screwed panel and may be mounted in a cage and may have adapter that fit on the hard drive connector pins.
Other hard drives are fitted on the edges of the LH side or RH side of the laptop behing a plastic panel and this panel is held in place by a screw. Again the hard drive may be mounted in a cage and may have an adapter connector on the hard drive connector pins.
If you are not sure goto the Toshiba WEB site to download the user manual or service manual for your model laptop.
