RM0211 4U ATX Rackmount Chassis Quick Installation Sheet


This installation sheet is designed for RM0211ATXBK and RM0211ATXBG 4U Rackmount Chassis.


Before Installation


Before you begin, please check the RM0211 box contents. The chassis box should contain the following: (See picture)





There are 11 mounting accessories come with RM0211 chassis.


If you any of these items are missing, please contact PCW Microsystems, Inc. for assistance. Tel: 516-997-5050


Tools for Installation


You will need a screwdriver for motherboard installation.


Power Supply Installation


Note: Skip this section, if the RM0211 unit already came with an ATX power supply pre-installed.


Standard ATX Power Supply






First, removing the two screws on each side of the chassis.



Next, loosen a thumbscrew at the back of the chassis. Slide the top cover off the chassis.



Remove the four screws that secured the clamp-down-bar. Lift the clamp-down-bar and you are ready to install an ATX power supply.



Align the ATX power supply to the back of RM0211 chassis opening.



Use the screw #1 or #7 to secure the ATX power supply.


Redundant ATX Power Supply

Please view installation process for RP8300.



Motherboard Installation


Before you begin, locate the mounting spacer number 8 and 9 from RM0211 mounting accessories pack. Mounting spacer number 8 is made of “brown” copper.Mounting spacer number 9 is made of metal.



Depending on your ATX motherboard’s mounting style, you will need to place either Copper Spacer # 8 or metal spacer #10 on to the RM0211 motherboard mounting plate.





Clip the metal spacer # 10 on to the chassis’s motherboard mounting plate.The alignments and positions of the metal mounting spacers should match the ATX motherboard’s mounting holes.




The copper screw number #8 is used to secure Pentium 4 ATX motherboard. These copper screws will help secure P4 CPU cooling fans.




Make sure that the mounting holes on the ATX motherboard match the holes on the metal spacer number 10.Use mounting screw number 1, 6 or 7 to secure the ATX motherboard on to the RM0211 mounting plate.



Connect the ATX power connector from the ATX power supply on to an ATX motherboard.



RM0211 chassis provides a set of status LED lights at the front of the chassis panel.The above picture shows connectors for RM0211 status LED lights.These connectors are Power LED, H.D.D LED, Power Switch, Reset Switch, USB Ports and speaker.

USB Port Connectors



Connect the chassis fan cable directly on to an ATX motherboard’s fan connector. Please note that not every ATX motherboard supports chassis fan option.





Alarm Board Installation


RM0211 has an optional internal temperature and fan failure alarm board (Model#RM0211-ISF08).



     RM0211 Temperature and Fan Failure Alarm Board(Alarm Board for short) supports 8 chassis fans and 2 temperature sensors.The sensitivity of the internal temperature sensor is adjustable between three temperature ranges (50, 60, 70 degree C).


Step 1: Setup the FAN detector setting


     RM0211 Alarm Board supports 8 internal chassis fans.First, determine the number of the chassis fan(s) to be connecting the alarm board.Next, connect the first chassis fan to the FAN1 connector on the Alarm Board.Following the sequence and connect second and third fans to the FAN2 and FAN3 connectors on the Alarm Board.Please keep in mind that FAN1 connector must be use (occupied) before connecting the FAN2 connector.After finish the connection, determine the number of chassis fan installed and set up the following jumper switch.

Step 2: Setup the Internal Temperature Sensors Setting


     RM0211 Alarm Board supports 2 temperature sensors (TS1 and TS2).When the Alarm Board detects the internal chassis temperature going over a predefined range, the Alarm board will go off notifying the system administrator.The sensitivity of these temperature sensors can be adjusted according to individual system preference.The following table shows the jumper settings for adjusting the RM0211 temperature sensors.In a normal operation condition, the internal temperature sensitivity setting should be set at 50 degree C.

Step 3: Connects the Power


     The Alarm Board requires a power source to operate. After setting up the Fan and temperature settings, connect a peripheral power connector to the Alarm Board. The Alarm Board has been successfully installed.



CD-ROM, Harddisk and Floppy Drive Installation


CD-ROM Drive, Hard Disk Drive and Floppy Drive installation is a simple process.



First remove the four (4) screws located at the top of the drive cage.




Lift the entire drive cage from the chassis body.



Install CD-ROM drive, floppy drive and hard disk drive directly in to the drive cage.



Secure the CD-ROM drive by fastens two screws on each side of the drive cage.Next, put the drive cage back to the RM0211 chassis body.
