Frequently Asked Questions - SC733i-645 Supermicro

How do I remove the side cover of the SC733 chassis?

Remove the two screws from the back lip of the side cover, then grab the handle and gently pull the cover toward you to release it. Slide the cover out of the chassis.

How do I install the motherboard?

First remove the rear exhaust fan by applying pressure to the tabs on the top and bottom of the fan, then snap it out. Install the motherboard after that.

How do I install a 5.25" device?

Remove the dummy tray by unscrewing it, attach the drive mounting rail to the device, slide it into the bay, and secure with screws.

How do I install 3.5" drives in the SC733i?

Remove the side cover, unscrew the three screws from the 3.5" drive brackets, pull the brackets toward the rear and out, install drives into brackets, then reinstall brackets and secure with screws.

How do I remove the front chassis cover?

Remove the side cover, lift the two tabs inside the bottom lip of the front cover, use a flat screwdriver to gently pry open, then pull the front cover off.

How do I access the control panel circuit board?

Remove the front cover, then remove the screw that fastens the control panel to the chassis. The circuit board can then be accessed.

What are the jumper settings on the SATA backplane?

For the SC733T backplane, JP25 sets overheat temperature (open: 45°C, pins 1-2: 50°C, pins 2-3: 55°C), JP28 enables/disables fan sense, JP26 for SATA drive activity, JP18 is buzzer reset alarm header.

How to clean or replace the rear exhaust fan?

Remove the side cover, press the tabs on the top and bottom of the fan to release it, pull the fan away, then install a new fan by snapping it in place.

What is included in the accessory box?

One set of motherboard screws, one set of drive screws, one set of HDD screws, one 5.25" drive mounting rail, one chassis lock mechanism, one set of front drive bay keys (for SC733T), and one AC power cord.

How to ensure proper airflow?

Keep all drive carriers in the drive bays to promote proper airflow. Ensure no ribbon cables touch the backplane or obstruct airflow holes. Do not touch the backplane with metal objects.

A. Unpacking and Check Lists

Please check to see if you have received all the items listed below:

The SC733 chassis contains the following:

One (1) 3.5" floppy drive
One (1) SATA backplane (SC733T)
Four (4) SATA drive carriers (SC733T)
One (1) 9-pin SATA LED cable (SC733T)

The accessory box contains the following:

One set of motherboard screws
One set of drive screws
One set of HDD (hard disk drive) screws
One (1) 5.25" drive mounting rail
One (1) chassis lock mechanism
One set of front drive bay keys (SC733T)
One (1) AC power cord

B. Removing the Side Cover of the SC733 Chassis

Before installing any components, replacing chassis fans or accessing the motherboard, you will first need to remove the side cover.

Procedure to remove the side cover

1. Remove the two screws from the back lip of the side cover (this is the left cover when you look at the chassis from the front.)
2. Grab the handle and gently pull the side cover toward your to release it from its position. Once the side cover is out of its position, slide the cover out of the chassis.

C. Removing the Rear Exhaust Fan and Installing the Motherboard

(You will need to remove the rear exhaust fan before you install the motherboard.)

Procedure

1. Remove the side cover from the chassis (refer to Section B).
2. Locate the exhaust fan tabs on the back panel (see picture below right.)
3. Apply pressure to the tabs (located on the top and the bottom of the rear exhaust fan) to snap the fan out of its locked position.
4. Pull the fan away from the chassis.

The airflow is directed to the hard drives, the add-on cards and the motherboard, resulting in optimal system cooling (SC733T).

Advantages of Supermicro's Cooling System

1. The rear exhaust fan is a thermal-control fan. It has been optimized for low noise operation, which is ideal for office and workstation environments.
2. Because of its uniquely designed shroud, the thermal-control front cooling fan can efficiently distribute air to the hard drives, the add-on cards and the overall system (SC733T).

D. Removing Components from or Installing Devices into the 5.25" Drive Bays

After removing the side cover from the chassis, you can remove or install devices into the drive bays (refer to Section B for removing the side cover).

Procedure

1. Remove the four screws from the 5.25" drive bay that you want to work with. (There are only 2 screws for the 3.5" floppy drive.)
2. Slide the 5.25" dummy tray out from the front. (You can also install a 3.5" device in the dummy tray located at the bottom of the 5.25" drive bays.)
3. Attach the drive mounting rail to the 5.25" device you wish to install and secure it with screws.
4. Once the rail is attached to the device, slide the device into the 5.25" bay and secure the device with screws.
5. Slide the side cover back to its position and secure it with screws.

E. Removing Components from or Installing Devices into the 3.5" Drive Bays (SC733i only)

(For the SC733T chassis, you can access the hot swappable 3.5" drives from the front side of the chassis without removing the side cover. Please make sure to secure the drive tray with four screws after you have installed components into it.)

Please follow the procedures listed below to remove the 3.5" drives in order to install components into the drive bay (SC733i).

Procedure

1. First, remove the side cover from the chassis so you can remove components from or install devices into drive bays (refer to Section B).

2. Remove the three screws from the 3.5" drive brackets.

3. Pull the brackets toward the rear first and then pull them out from the chassis.

4. Install the 3.5" drive into a bracket and secure it with screws.

5. Once you've installed the 3.5" drives into the brackets, place the back assembly with the drives into the chassis.

6. Secure the bracket with the three screws you removed earlier.

7. Slide the side cover back to position and secure it with screws.

F. Removing the Front Chassis Cover and Accessing the Control Panel

(Unless you need to access the control panel's circuit board or the floppy drive, we do not recommend removing the front cover.)

Procedure

1. Remove the side cover from the chassis (refer to Section B).
2. Lift the two tabs inside the lip located at the bottom of the front cover.
3. Using a flat screw driver, gently pry open the front cover.
4. Once one side of the front cover is loose, pull the front cover completely out of the chassis as shown in Figure B.
5. You can also remove the control panel's circuit board by removing the screw that fastens the control panel to the chassis.

G. Configuring Jumper Settings for the Serial ATA Backplane

Important! Use extreme caution when working around the SATA backplane. Do not touch the backplane with any metal objects and make sure that no ribbon cables touch the backplane or obstruct the airflow holes in the SATA backplane. All SATA drive carriers must remain in the drive bays to promote proper airflow.

The Serial ATA (SATA) backplane supports four SATA drives. The SATA733 backplane is shown on the picture on the next page. The SATA drives' LED connector on the SATA backplane is JP26. There are also two power connectors on the backplane, and both connectors should be connected. Please do not cascade the SATA backplane. Please refer to the following table for the jumper settings:

Jumper	Description Setting
JP18 Buzzer Reset Alarm Reset Header
JP25	Overheat Temperature Open: 45 Pins 1-2: 50irc C (Default) Pins 2-3: 55irc C
JP26 SATA Drive Activity Drive Activity
JP28 Fan Sense Pins 1-2: Enable		Pins 2-3: Disable (Default)

(*Note: Please refer to the figures on the next page for the jumper locations.)
