This chapter provides a quick setup checklist to get your RMC 7152 up and running. FOllowing the steps in the order given
should enable you to have the system operational within a minimal amount of time. This quick setup assumes that your
system has come to you with the processor and memory preinstalled. If your system is not already fully integrated with a
serverboard, processor, system memory etc., please turn to the chapter or section noted in each step for details on installing
specific components.
2.2 Unpacking the System
You should inspect the box the server was shipped in and note if it was damaged in any way. If the server itself shows
damage, you should file a damage claim with the carrier who delivered it.
Decide on a suitable location for the rack unit that will hold the server. It should be situated in a clean, dust-free area that is
well ventilated. Avoid areas where heat, electrical nose and electromagnetic fields are generated. You will also need it placed
near a grounded power outlet. Read the rack and server precations in the next section.
2.2 Preparing for Setup
The RMC 7152 does not ship with a rack rail hardware package as the system can be rack mounted without the use of rails.
An optional rack rail package is available if you wish to order from Acnodes. Follow the steps in the order given to complete
the installation process in a minimal amount of time. Please read this section in its entirety before you begin the installation
procdeure outlined in the sections that follow.
This section provides information on installing the RMC 7152 into a rack. If the system has already been mounted into a
rack, you can skip ahead to Sections 2-5 and 2-6.
There are a variety of rack units on the market, which may mean the assembly procedure will differ slightly. The following is a
guideline for installing the unit into a rack with the rack rails provided with the system. You should also refer to the installation
instructions that came with the rack unit you are using.
Basic Installation Procedure
You should have received two rack rail assemblies with the RMC 7152. Each of these assemblies consist of two sections: an
inner fixed chassis rail that secures to the unit (A) and an outer fi xed rack rail (B) that secures to the rail brackets. A sliding
rail guide sandwiched between the two should remain attached to the fixed rack rail (see Figure 2-1). The A and B rails must be
detached from each other to install.
To remove the fixed chassis rail (A), pull it out as far as possible - you should hear a "click" sound as a locking tab emerges
from inside the rail assembly and locks the inner rail. Then depress the locking tab to pull the inner rail completely out. Do this
for both the left and right side rack rail assemblies.
Figure 2-1. Identifying the Sections of the Rack Rails
Position the fixed chassis rail sections you just removed along the side of the chassis making sure the five screw holes line up.
Note that these two rails are left/right specific. Screw the rail securely to the side of the chassis (see Figure
2-2). Repeat this procedure for the other rail on the other side of the chassis. You will also need to attach the rail brackets
when installing into a telco rack.
Locking Tabs: As you have seen, both chassis rails have a locking tab, which serves two functions. The first is to lock the
server into place when installed and pushed fully into the rack, which is its normal position. Secondly, these tabs also lock the
server in place when fully extended from the rack. This prevents the server from coming completely out of the rack when you
pull it out for servicing.
Determine where you want to place the RMC 7152 in the rack (see Rack and Server Precautions in Section 2-3). Position the
fixed rack rail/sliding rail guide assemblies at the desired location in the rack, keeping the sliding rail guide facing the inside of
the rack. Screw the assembly securely to the rack using the brackets provided. Attach the other assembly to the other side of
the rack, making sure that both are at the exact same height and with the rail guides facing inward.
Installing the Server Into the Rack
You should now have rails attached to both the chassis and the rack unit. The next step is to install the server into the rack. Do
this by lining up the rear of the chassis rails with the front of the rack rails. Slide the chassis rails into the rack rails, keeping
the pressure even on both sides (you may have to depress the locking tabs when inserting). See Figure 2-3.
When the server has been pushed completely into the rack, you should hear the locking tabs "click".
If you are installing the RMC 7152 into a Telco type rack, follow the direc- tions given on the previous pages for rack installation. The only difference in the installation procedure will be the positioning of the rack brackets to the rack. They should be
spaced apart just enough to accomodate the width of the telco rack.
After you install the server in the rack, you will need to open the unit to make sure the serverboard is properly installed and all
the connections have been made.
Removing the Chassis Cover
1. Release the retention screws that secure the unit to the rack.
2. Grasp the two handles on either side and pull the unit straight out until it locks (you will hear a “click”)
3. Remove the screws from the rear lip of the chassis cover (See figure 2-5)
4. Release the top cover by pushing it away from you until it stops. You can then lift the top cover from the chassis to gain full
acccess to the inside of the server.
Checking the Components
1. You may have processors already installed in the serverboard. Each processor should have its ownheatsink attatched.
2. The RMC 7152 server may have come with the system memory already installed. Make sure all DIMMs are fully seated in
their slots.
3. If desired, you can install an add-on card to the system.
4. Make sure all power and data cables are properly connected and not blocking the airflow.
2.6 Checking the Drive Bay Setup
Next, you should check to make sure the peripheral drives and the SATA drives have been properly installed and all essential
connections have been made.
Checking the Drives
- For servicing the DVD-ROM and floppy drives, you will need to remove the top chassis cover.
- The Serial ATA disk drives can be installed and removed from the front of the chassis without removing the top
chassis cover.
- Depending upon your system's configuration, your system may have one or two Serial ATA drives already installed.
If you need to install Serial ATA drives.
Checking the Airflow
- Airflow is provided by two 10-cm input fans. The system component layout was carefully designed to promote
sufficient airflow through the small 1U rackmount space.
- Also note that all power and data cables have been routed in such a way that they do not block the airflow gener-
ated by the fans.
Providing Power
- The last thing you must do is to provide input power to the system. Plug the power cord from the power supply unit
into a high-quality power strip that offers protection from electrical noise and power surges.
- It is recommended that you use an uninterruptible power supply (UPS).
There are several LEDs on the control panel as well as others on the SATA drive carriers to keep you constantly informed of the
overall status of the system as well as the activity and health of specific components. There are also two buttons on the
chassis control panel. This chapter explains the meanings of all LED indicators and the appropriate response you may need to
take.
3.2 Control Panel Buttons
There are two push buttons located on the front of the chassis: a reset button and a power on/offbutton.
The reset switch reboots the system
This is the main power switch, which is used to apply or turn off the main system power. Turning off system power with this
button removes the main power but keeps the standby power supplied to the system.
The control panel located on the front of the RMC 7150 chassis has five LEDs. These LEDs provide you with critical information
related to different parts of the system. This section explains what each LED indicates when illuminated and any corrective
action you may need to take.
Overheat/Fan Fail
When this LED flashes it indicates a fan failure. When on continiously (on and not flashing) it indicates an overheat condition,
which may be caused by cables obstructing the airflow in the system or the ambient room temperature being too warm. Check
the routing of the cables and make sure all fans are present and operating normally. You should also check to make sure that
the chassis covers are installed. Finally, verify that the heatsinks are installed properly. This LED will remain flashing or on as
long as the overheat condition exists.
Indicates network activity on LAN2 when flashing.
Indicates network activity on LAN1 when flashing.
Channel activity for HDDs. This light indicates IDE drive activity when flashing.
Indicates power is being supplied to the system’s power supply units. This LED should normally be illuminated when the
system is operating.
Each Serial ATA drive has both a green and a red LED.
- Green: Each SATA drive carrier has a green LED. When illuminated, this green LED (on the front of the SATA drive
carrier) indicates drive activity. A connection to the SATA backplane enables this LED to blink on and off when that particular
drive is being accessed.
- Red: The red LED to indicate an SATA drive failure. If one of the SATA drives fail, you should be notified by your
system management software. Please refer to Chapter 6 for instructions on replacing failed SATA drives.
Basic electrical safety precautions should be followed to protect yourself from harm and the RMC 7152 damage:
- Be aware of the locations of the power on/off switch on the chassis as well as the room’s emergency power on/off
switch, disconnection switch or electrical outlet. If an electrical accident occurs, you can then quickly remove power from the
system.
- Do not work alone when working with high voltage components.
- Power should always be disconnected from the system when removing or installing main system components,
such as the serverboard, memory modules and floppy drive. When disconnecting power, you should first power down the
system with the operating system first and then unplug the power cords of all the power supply units in the system.
- AWhen working around exposed electrical circuits, another person who is familiar with the power-off controls should
be neaerby to switch off the power if necessary.
- Use only one hand when working with powered-on electrical equipment. This is to avoid making a complete circuit,
which will cause electrical shock. use extreme caution when using metal tools, which can easily damage any electrical
components or circuit boards they come into contact with.
- Do not use mats designed to decrease static electrical discharge as protection from electrical shock. Instead, use
rubber mats that have been specifically designed as electrical insulators.
- The power supply power cords must include a grounding plug and must be plugged into grounded electrical outlets.
- This product may be connected to an IT power system. In all cases, make sure that the unit is also relably connected to Earth.
- Serverboard Battery: CAUTION - There is a danger of explosion if the onboard battery is installed upside down,
which will reverse its polarities. This battery must be replaced only with the same or an equivalent type recommended by the
manufacturer. Dispose of used batteries according to the manufacturer’s instructions.
- DVD-ROM Laser: CAUTION - This server may have come equipped with a DVD-ROM drive. To prevent direct
exposure to the laser beam and haardous radiation exposure, do not open the enclosure or use the unit in any unconventional way.
- Mainboard replaceable soldered-in fuses: Self-resetting PTC (Positive Temperature Coefficient) fuses on the
mainboard must be replaced by trained service technicians only. The new fuse must be the same or equicalent service
technicians only. The new fuse must be the same or equivalend as the one replaced. Contact technical support for details
and support.
4.2 General Safety Precautions
Follow these rules to ensure general safety:
- Keep the area around the RMC 7152 and free of clutter.
- The RMC 7152 weighs approximately 18 lbs. when fullyloaded. When lifting the system, two people at either end
should lift slowly with their feet spread out to distribute the weight. Always keep your back straight and lift with your legs.
- Place the chassis top cover and any system components that have been removed away from the system or on a
table so that they won’t accidentally be stepped on.
- Remove any jewelry or metal objects from your body, which are excellent metal conductors that can create short
circuits and harm you if they come into contact with printed circuit boards or areas where power is present.
- After accessing the inside of the system, close the system back up and secure it to the rack unit with the retention
screws after ensuring that all connections have been made.
Electrostatic Discharge (ESD) is generated by two objects with different electrical charges coming into contact with each other.
An electrical discharge is created to neutralize this difference, which can damage electronic components and printed circuit
boards. The following measures are generally sufficient to neutralize this difference before contact is made to protect your
equipment from ESD:
- Use a grounded wrist strap designed to prevent static discharge.
- Keep all components and printed circuit baords (PCDs) in their antistatic bag.
- Do not let components or PCBs come into contact with your clothing, which may retain a charge even if you are
wearing a wrist strap.
- Handle a board by its edges only; do not touch its components, peripheral chips, memory modules or contacts.
- When handling chips or modules, avoid touching their pins.
- Put the serverboard and peripherals back into their antistatic bags when not in use.
- For grouding purposes, make sure your computer chassis provides excellent conductivity between the power supply,
the case, the mounting fasteners and the serverboard.
4.4 Operating Precautions
Care must be taken to assure that the chassis cover is in place when it is operating to assure proper cooling. Out of warranty
damage to the system can occur if this practice is not strictly followed.
This chapter covers the steps required to install the serverboard into the chassis, connect the data and power cables and
install add-on cards. All serverboard jumpers and connections are also described. A layout and quick reference chart are
included in this chapter for your reference. Remember to completely close the chassis when you have finished working with the
serverboard to better cool and protect the system.
5.1 Handling the Serverboard
Electrostatic Discharge (ESD) can damage electronic components. To prevent damage to any printed circuit boards
(PCBs), it is important to handle them very carefully (see previous chapter). To prevent the serverboard from bend- ing, keep one
hand under the center of the board to support it when handling. The following measures are generally sufficient to protect your
equipment from electric static discharge.
Precautions
- Use a grounded wrist wrap strap designed to prevent ESD.
- Touch a grounded metal object before removing any board from its antistatic bag.
- Handle a board by its edges; do not touch its components, peripheral chips, memory modules or gold contacts.
- When handling chips or modules, avoid touching their pins.
- Put the serverboard, add-on cards and peripherals back into their antistatic bags when not in use.
- For grounding purposes, make sure your computer chassis provides excellent conductivity between the power supply,
the case, the mounting fasteners and the serverboard.
Unpacking
The serverboard is shipped in antistatic packaging to avoid electrical static discharge. When unpacking the board make sure
the person handling it is static protected.
5.2 Server Installation
This section explains the first step of physically mounting it into the chassis. Following the steps in the order given will eliminate most common problems encountered in such an installation. To remove the serverboard, follow the procedure in reverse
order.
Installing to the Chassis
1. Remove the screws from the rear lip of the chassis cover.
2. Release the top cover by pushing it away from you until it stops. You can then lift the top cover from the chassis to gain full
access to the inside of the server.
3. Make sure that the I/O ports on the serverboard align properly with their respective holes in the I/O shield at the back of the
chassis.
4. Carefully mount the serverboard to the serverboard tray by aligning the board holes with the raised metal standoffs that are
visible to the chassis.
5. Insert screws into all the mounting holes on your serverboard that line up with the standoffs and tighten until snug.
Now that the serverboard is installed, the next step is to connect the cables to the board. These include the data cables for the
peripherals and control panel and the power cables.
Connecting Data Cables
The cables used to transfer data from the peripheral devices have been carefully routed to prevent them from blocking the flow of
cooling air that moves through the system from the back. If you need to disconnect any of these cables, you should take care
to keep them routed as they were originally after reconnecting them.
The following data cables should be connected.
- DVD-ROM cable
- SATA drive cables
- Control Panel cable
Connecting Power Cables
It has a 24-pin primary power supply connector for connection to the ATX power supply. In addition, there are two 8-pin processor connectors that also must be connected to your power supply.
